The Unity of God and Ontic Participation in the Thought of Irenaeus by Scott Fulcher, Tim Hahn, Levi Jones, and Jonathan Platter


Irenaeus of Lyons was a bishop active in the latter half of the second century in what is now southern France. Born and raised in Asia Minor, he claims to have been a student of Polycarp, and to remember the martyr’s teachings well. Eusebius of Caesarea attributed several works to Irenaeus, but only two survive in their entirety:[1] The Demonstration of the Apostolic Teaching and The Identification and Refutation of Gnosis Falsely So-Called (hereafter Against Heresies).

An educated man, it is assumed that he spent time in Rome prior to his ministry in Lyons, and is known to have been sent back to Rome as a messenger on behalf of the martyrs of Lyons and Vienne. Beyond this, and the letter Eusebius tells us he wrote to Victor, bishop of Rome, on behalf of the churches of Asia, almost nothing more is known of Irenaeus’s life.

His extant writings, however, are significant in the history of Christian thought, as they represent one of the first steps toward a systematic approach to Christian theology. Against Heresies, in particular, contains substantial material useful for the identification of a ‘theology of Irenaeus.’ Within his theology several themes are evident yet this space is insufficient to cover them all. This paper seeks to emphasize and discuss the ontologically-participatory aspects of Irenaeus’s thought in their nascent trinitarian[2] setting. However, it would be negligent to proceed with this discussion without first acknowledging the context from which Irenaeus’s theology comes to us, and in relation to which it must be understood: the Gnostic threat.


Polemical Context

“Gnosticism” is a very difficult term to define. Scholarly literature uses the word to describe a wide variety of religious phenomena. Chronologically, these religions can be found to exist from the first century A.D. to the ninth. Geographically they span a region that stretches from Gaul to Iran. The term describes “systems which ambivalently love and scorn the world and systems which explicitly hate the world.”[3] It must be acknowledged, then, that using the term “Gnosticism” or “Gnostic” involves working under some considerable assumptions. Scholars have been careful to assert that the views Irenaeus opposed in Against Heresies are not necessarily those of all ‘Gnostics.’

Of the many systems of Gnosticism to which Irenaeus responded in Against Heresies, modern scholarship is best acquainted with Valentinianism. As was not unusual in Gnostic schools, the students of Valentinus[4] developed and built upon his ideas, often reaching conclusions Valentinus never approached. Osborn details six “points of divergence” between Valentinus and his students: the creation of man, the unity and accessibility of “the father,” the number and nature of “Christs,” the good or evil nature of the world, the place (or lack thereof) of Sophia in the creation myth, and the interpretation of biblical texts.[5]

It is to these divergences, particularly those touching on the unity of God and the nature of Christ and the world, that the theological elements outlined below respond. For the purposes of this paper ‘Gnosticism’ will refer to the thought of Valentinus’s students, as encountered by Irenaeus.[6]

            The stated purpose for Irenaeus’s writing of Against Heresies was “to expose and counteract [the Gnostics’s] machinations.”[7] As bishop of Lyons, it was Irenaeus’s express obligation to protect his congregation from false teachings. The teaching role of the bishop is central to Irenaeus’s view of the church, and the writing of his great polemic work is the most lasting of his own efforts in that regard. Of the many things to which Irenaeus objects within Gnosticism, those aspects most pertinent to our purposes here are the disunity of God and the low view of humanity.

            God’s disunity is an aspect of Gnostic thought that one hardly needs to dig for. Irenaeus spends a great deal of time outlining the often-complicated Gnostic views of God:

There is a perfect pre-existent Aeon, dwelling in the invisible and unnamable elevations; this is Pre-Beginning and Forefather and Depth. He is uncontainable and invisible, eternal and ungenerated, in quiet and in deep solitude for infinite aeons. With him is Thought, which is also called Grace and Silence. Once upon a time, Depth thought of emitting from himself a Beginning of all, like a seed, and he deposited this projected emission, as in a womb, in that Silence who is with him. Silence received this seed and became pregnant and bore Mind, which resembled and was equal to him who emitted him… Along with him, Truth was emitted; this makes the first Four, the root of all: Depth and Silence, then Mind and Truth.[8]

Immediately in his description of the Gnostic heresy, the God described is not one, but rather four. Prior to any emanations, even, there are two characters on the divine stage: Depth and Silence. Depth, though involved in an apparently sexual fashion with Silence, is “in quiet and in deep solitude for infinite aeons.”[9] The Gnostic God is both distant and many, both claims countered by Irenaeus in the later books of his work as he insisted on both the unity and immediacy of God.

Similarly, Gnostic theology held a low view of humanity:

There are these three elements in man: the material, also called “left,” which necessarily perishes since it cannot possibly receive the breath of imperishability; the psychic, also called “right,” which lies between the spiritual and the material and extends to either one as it has the inclination; the spiritual, which was sent forth to be shaped in union with the psychic and to be instructed with it in its conduct. This [last element] is the “salt” and the “light of the world” [Matt. 5:13-14]… And the Saviour came to this psychic element, since it has free will, in order to save it. He assumed the primary elements of those beings which he was going to save. From Achamoth he took the spiritual, from the Demiurge he put on the psychic Christ, and from the constitution of the universe he acquired a body which had psychic substance and was constructed by ineffable art so to be visible, tangible, and subject to passion. He acquired nothing material at all, for matter is not capable of being saved.[10]

The division of mankind into three elements serves to justify the Gnostic separatism that Irenaeus confronts in Against Heresies. Further, there is a clear division between the physical world and the spiritual world, each categorically different from the other. Humans, then, can be portioned into these three elements. The physical material of the body and the earth surrounding it is irredeemable, unable to accept imperishability. The psychic part of the human exists in between the two poles of physicality and spirituality, and can be moved in either direction. Lastly is the spiritual, the spark of the divine which allows a human to understand the way reality is. Jesus, in this Gnostic system, came to the middle portion, in order to bring it to the spiritual side and ‘save it.’

            Also evident in this passage, is the plurality not only of God, with both Achamoth and the Demiurge being referenced, but the plurality of Jesus Christ. The Gnostic system which Irenaeus details here divides the Savior into the spiritual emanation Jesus, and the psychic Christ, which work together, in an ineffably artistic body, to save the psychic element of humanity. Central to Irenaeus’s objections, and his subsequent alternatives, is the final assertion above, that the Savior did not include anything which was material, for matter was the first element, the purely physical one, and was not capable of being saved.[11]

The above representations of Gnosticism come from Against Heresies and have been questioned as to their faithfulness given the polemical motivation of the work. Similar sentiments are found, however, in the Gnostic (Valentinian) document The Gospel of Truth. Irenaeus identified the work in Against Heresies, but briefly, and only just to note how wildly it differed from the canonical gospels.[12] This document was found in 1945-1946 with the discovery of the Nag-Hammadi papyri along with a Gospel of Philip which also featured prominently in discussions of Valentinian Gnosticism.[13] A certain passage from this text displays the faithfulness of Irenaeus’s presentation of his opponents:

There is a householder who had every conceivable thing, be it son or slave or cattle or dog or pig [or] barley or chaff or grass or […] or meat and acorn. [Now he was] a sensible fellow and he knew what the food of each one was. He served the children bread […]. He served the slaves […] meal. And [he threw barley] and chaff and grass to the cattle. He threw bones to [the] dogs, and to the pigs he threw acorns and slop. Compare the disciple of God: if he is a sensible fellow he understands what discipleship is all about. The bodily forms will not deceive him, but he will look at the condition of the soul of each one and speak with him. There are many animals in the world which are in human form. When he identifies them, to the swine he will throw acorns, to the cattle he will throw barley and chaff and grass, to the dogs he will throw bones. To the slaves he will give only the elementary lessons, to the children he will give the complete instruction.[14]

This lengthy passage provides a highly metaphorical representation of the division of humanity into different hierarchically valuable segments corresponding to their ability to be saved. The children of the passage represent those capable of receiving the salvific knowledge, while the pigs or the ‘animals…which are in human form’ refer to those who are not. While the metaphor is elegant, the low view of humanity (and willingness to divide the body) expressed within this passage are intolerable for Irenaeus.

            To these positions, amongst many others, Irenaeus wrote his Against Heresies. Central to his response was the unity of God and the participatory nature of salvation. God’s unity is shown forth in implicitly trinitarian language, as the transcendent God is made immediate through the actions of the Son and the Spirit, and salvation by secret knowledge, divorced from matter, is rejected as humanity’s role in the economy of salvation is embraced.


The Son and Ontic-Participation

Throughout Against Heresies, Irenaeus stresses the concept of unity: one God, one scripture, one faith handed down from the apostles. An important aspect of the unity of God in Irenaeus’s work is his defense that Jesus, Christ, and the Savior are all referring to the one Word of God.  This conception of the unity of the Son was a necessary response to the Gnostic notion that each of these is separate.

The Word’s incarnate revelation of God and recapitulation of humanity through his fellowship and sacrifice gives full meaning to human participation in God. In this section, we will explore how humanity is brought into fellowship with God through the revelation of the Word and the doctrine of recapitulation in the writing of Irenaeus.


Images for the Son

Irenaeus uses many different names and titles to refer to the Son in Against Heresies. The most common way that Irenaeus refers to the Son is as the Word or Word of God. Other names and titles that Irenaeus uses to refer to the Son include: Son of God, Son of man, Jesus, Christ, Lord, second Adam, Salvation, ruler of heaven and earth, judge of the living and the dead, head of the church, first fruits of the resurrection, the fulfillment of the law. It was important for Irenaeus to show how each of these were simply different titles describing the economic activity of the One Son of God. The Gnostic teachers that Irenaeus rebuffed tended to break up the Son so that Jesus and Christ represented two different individuals.


The Son and Ontic-Participation as Revelation and Recapitulation

Throughout scripture and history, the Word has served as the revelation of God to humanity in several ways. Jesus is the Word through which God spoke creation into existence.[15] The Word was the initial revelation of God by being the voice that spoke with Adam, Abraham, Moses, and the prophets. “In the last times the very same Word of God came to call humankind, reminding them of their doings, lives which they had tried to hide from the Lord. For just as at that time God spoke to Adam in the evening, searching him out, so in the last times, by means of the same voice searching out his posterity, he has visited them.”[16]

The Word incarnate becomes the ultimate revelation of God, speaking words about the Father, living in the manner the Father desires, and inviting mutual relationship with all of Creation. “We could have learned no other way than by seeing our teacher and hearing his voice with our own ears.”[17] The Word opens up space in us so that we might experience and participate in the new creation (salvation) God is working.

The Gnostics took Scripture and bent it to fit their schemes, packaged as a new and secret revelation, in the following ways: reinterpreting scripture in a manner different than the apostles, adding to scripture, and removing pieces that did not fit their Gnostic agenda. Central to Irenaeus’s mission was the protection of the revelation of God as presented in scripture and in the tradition passed down from the apostles, which proclaimed Christ.

“The Father made his salvation (that is, his Word) visible to all flesh, by the Word himself becoming incarnate, so that in all things their king might become manifest.”[18] The Word taking on flesh was necessary for both God to be revealed to humanity, and humanity to be invited into fellowship with God. Irenaeus gives a good explanation of this in his interpretation of the Spirit descending on Jesus in his baptism:

By fellowshipping with him (Jesus), the Spirit became accustomed to living in the human race, resting upon human beings, and dwelling in the handiwork of God, in order to accomplish the will of the Father in them and renew them from their old habits into the newness of Christ.[19]

The Word incarnate, fully God and fully human, is the conduit through which humanity and God are able to be in relationship. Jesus, the fully mature human, becomes the space where the Spirit becomes accustomed to dwelling among humanity. Just as the Spirit required the mediation of Jesus in order to be acclimated to humanity, humanity was able to receive the revelation of God because it was wrapped in flesh. Thus, the Word is the full revelation of God and the full revelation of humanity for the purpose of bringing God and humanity into fellowship. “The glory of God is a human being fully alive, and the life of a human being consists in beholding God… the revelation of the Father which comes through the Word give(s) life to those who see God.”[20]  The purest example of God’s glory is shown in the life of a human who has beheld God in Christ and chosen to fully dive into the relationship of love that God extends to humanity. By beholding God, and receiving that revelation in a manner where the human responds in loving submission and obedience to the will of God, that human becomes fully alive in Christ and thus becomes a beacon of God’s glory to the rest of creation.

Recapitulation highlights the manner in which Jesus made it possible for humanity and God to be in fellowship. Irenaeus believed that it was the mission of the Word, by becoming human among humankind, to join the end to the beginning – that is, humanity to God.[21] “When he became incarnate and was made human, he began anew the long line of human beings and, to state it briefly, furnished us with salvation. Consequently, what we had lost in Adam – namely, the image and likeness of God – we recovered in Christ Jesus.”[22] In other words, because God took on the fullness of humanity, humanity might receive the fullness of God’s life.

Jesus lived his human life in a manner that revealed to the rest of humanity what it means to be a fully matured human. To Irenaeus, creation was made immature with the purpose of progressing toward maturity. Jesus lived a human life and faithfully endured everything that the first Adam faced. Where the first Adam displayed his immaturity, Jesus, the second Adam, displayed full maturity. By being obedient where the first Adam failed, Jesus embodied what it means to be a fully mature human. Jesus participated in God through loving obedience, to the point of death. Through the process of recapitulation Christ makes it possible for humanity to become the children of God. “He became the Son of man for this purpose, that humans also might become the children of God… so that he might win back to God that human nature which had departed from God.”[23]

Irenaeus’s doctrine of recapitulation establishes the importance of the physical creation. By showing that God physically became human, and now dwells in and among humanity, Irenaeus destroys the Gnostic idea that the body is evil and salvation is only for the spirit or soul. This doctrine also serves as an argument for the unity of Jesus’s human and divine aspects since both were necessary to redeem humanity and restore fellowship.


Humanity and Christ in Ontic-Participation as Obedience and Eucharist

We have given two ways in which the Son has acted to facilitate ontic-participation: revelation and recapitulation. Now, we will consider two examples drawn from Irenaeus’s writing detailing humanity’s movement toward the Son in order to enter into a relational fellowship with God: obedience[24]and Eucharist.

Jesus redeemed us from apostasy with his own blood so that we could become a holy people.[25] Unlike the Gnostics, who believed that participation in God came through knowledge, Irenaeus believed that humanity becomes the “holy people” of God through relationship (following God without fetters) with Christ which fosters obedience.[26] People learn about relationship and obedience from the Church of which Christ is the head.

The Church maintains faithful teaching (revelation). People learn what is necessary to be obedient through discipleship and relationship. It is important to note that this obedience is different than obligation. Humanity was enslaved to sin. The law (given by the Word) provided a way for humanity to move closer to God by becoming enslaved to the law itself rather than to sin. Jesus provides complete freedom through relationship for people to be united with God and free from sin by being obedient out of love for the relationship rather than out of obligation. Irenaeus made it clear that the proper response to the revelation of God in Christ was not slavery to God but rather fellowship in a loving relationship.[27]

The second way Irenaeus shows people participating in God through the Son is by partaking in Eucharist. The cup of blessing that we share is a sharing in the blood of Christ. This is significant to Irenaeus because the blood not only redeems us, but our bodies are united in the washing of Jesus blood.[28] Through the bread we partake in the body of Christ. The Eucharist sums up the significance of the life and passion of Christ as Irenaeus saw it:

The Lord has redeemed us through his own blood, giving his soul for our souls and his flesh for our flesh, and has poured out the Spirit of the Father for the union and communion of God and humankind, imparting to humanity by means of the Spirit. On the other hand he has united humanity to God by his own incarnation and, through communion with God, genuinely and lastingly bestowed immortality on us by his coming.[29]

By partaking in the Eucharist we are obedient to Christ’s request to do so, and we are reminded how we are drawn into fellowship with God through Christ.

Through the revelation and recapitulation accomplished by the Word, Irenaeus gives us an understanding of the role that the Word plays in bringing God and humanity together:

He is a most holy and merciful Lord, and he loves humanity…[30] He caused human nature to cleave to and become one with God… Unless humanity had been joined to God, humanity could never become a partaker of incorruptibility. So, it was incumbent upon the mediator between God and men, via his relationship to both, to bring them to friendship and peace, and so to present humankind to God, while revealing God to humankind.[31]

Through Christ, humankind became accommodated to union with the divine, but it is through the Spirit that the divine becomes accommodated to humanity.


The Spirit and Ontic-Participation

A weak pneumatology fosters a narrow soteriology. Kärkkäinen demonstrates the connection between the lack of emphasis on theosis in the West and an insufficient pneumatology.[32] Irenaeus develops his theology of theosis and participation in a thoroughly and robustly pneumatological context. In this regard, the irenic spirit that impelled his writing can provide an opportunity for irenic and ecumenical dialogue today.

Brendan Leahy argues that Irenaeus understands the trinity as the symphonic rhythm by which creation is brought to fulfillment. “The Spirit … is the ‘hand of God’ who is ‘hiding’ behind the works of creation, the economy of the Old Testament, the Incarnation, the baptism of Jesus Christ, the recapitulation of all things in Christ, and the Church. The Spirit is seen in his effects, principal among them our human fulfillment, glorification and deification.”[33] In this section we will explore the theme of human transformation through the Spirit’s agency within creation in Irenaeus’s theology.


Images for the Holy Spirit

In Against Heresies, Irenaeus spends some time discussing the Holy Spirit. For him, the Holy Spirit is identified in the Old Testament as God’s spirit, holy spirit, or spirit. He uses Psalm 51:10-12 as an example of David’s pleading for the Holy Spirit. This connection is made explicit by pairing it with Pentecost:

This Spirit did David ask for the human race, saying, “And establish me with Thine all-governing Spirit” [Ps. 51:12]; who also, as Luke says, descended at the day of Pentecost upon the disciples after the Lord’s ascension, having power to admit all nations to the entrance of life… from whence also, with one accord in all languages, they uttered praise to God, the Spirit bringing distant tribes to unity, and offering to the Father the first-fruits of all nations.[34]

Already in this one passage, Irenaeus has offered multiple metaphors and images for the Spirit’s action. The Spirit is “all-governing,” “divine power,” the “entrance of life,” “unity,” and “offering to the Father the first-fruits.”

Even more unique is Irenaeus’s use of “water” to depict the Holy Spirit’s activity. Thus, he says:

And as dry earth does not bring forth unless it receive moisture, in like manner we also, being originally a dry tree, could never have brought forth fruit unto life without the voluntary rain from above. For our bodies have received unity among themselves by means of that laver which leads to incorruption; but our souls by means of the Spirit … Our Lord compassionating that erring Samaritan woman … by pointing out and promising to her living water, so that she should thirst no more … The Lord, receiving this as a gift from His Father, does Himself also confer it upon those who are partakers of Himself, sending the Holy Spirit upon the earth.[35]

This is a fascinating passage; in part because of the volume of images and scenes he is pulling together. The Spirit is like water that makes it possible for a tree to produce fruit, so the Spirit gives our souls and bodies the eternal life that would not be ours without the Spirit. This water is the water promised to the Samaritan woman at the well; it is also the Spirit the Father gave to Christ, and whom Christ gives to us. This latter image, the Spirit being shared with Christ and with us, and thereby transforming our lives into conformity with the abundance of his, is reiterated and recontextualized when Irenaeus later deals with the Eucharist.

But our opinion is in accordance with the Eucharist, and the Eucharist in turn establishes our opinion. For we offer to Him His own, announcing consistently the fellowship and union of the flesh and Spirit. For as the bread, which is produced from the earth, when it receives the invocation of God, is no longer common bread, but the Eucharist, consisting of two realities, earthly and heavenly; so also our bodies, when they receive the Eucharist, are no longer corruptible, having the hope of the resurrection to eternity.[36]

The Spirit, who has already been identified as life giving, unifying (between persons), and power, is now the power of Christ’s presence in the Eucharist. This gives form to the Spirit’s agency in a few ways. The Spirit, through communion, is the unity of our flesh and spirit. To elucidate this, Irenaeus offers an explanation that presumes the reader agrees; the Spirit does this work of unification within us just as the earthly bread and the heavenly elements are united in the Eucharist.[37] It seems plausible to assume that Irenaeus intends the reader to also apprehend that the agent of this Eucharistic union is the Spirit, bringing the person of Christ into unity with the common elements.

Another remarkable aspect of Irenaeus’s pneumatology is that the union between our body and spirit which is achieved by the Spirit through the Eucharist is both the granting of incorruptibility to one’s body and making present the hope of resurrection. The Spirit’s life-giving power was given to Jesus at the baptism and works in us in communion.

In the context of Against Heresies, this pneumatology serves two main functions: 1) it demonstrates that the Spirit is the power who descended on Jesus at his baptism, which was contrary to the Gnostics who taught that at the baptism “Christ” descended and was incarnate; rather, Irenaeus argues, Jesus was already God-incarnate and became Spirit-empowered at the baptism scene; and 2) it argues for a more holistic anthropology; the Gnostics argued that the divine spark was given man even though man was created by the Demiurge, Irenaeus rebuts with the claim that body and spirit are both creaturely and have the same origin: God; further, we even rely on God to uphold and unify our very persons.[38]

Hence, contra the Gnostics, the human spirit is not a semi-divine or divine spark endowed with immortality waiting to be free of the corrupt body, but is also corruptible, bound to the body, and in need of the Spirit’s unifying, life-giving breath to receive incorruptibility and the hope of resurrection (which does not happen without the body).

So, for Irenaeus, the Spirit is central – for the unity of the Godhead, communities, and body and soul; for the power of God, of Jesus’ life, death and resurrection, and for human action; for the life of God’s creation, for Jesus’s life and resurrection life, and for opening the entrance to eternal life in Christ for humans. Take away these significant actions of the Spirit and one is approaching the position of the Gnostics Irenaeus is arguing against. Uphold them and give them place of preference and one is significantly closer to a robust doctrine of trinity, atonement, and anthropology.


The Spirit and Ontic-Participation as Transformation and Obedience

The Spirit, at the baptism of Jesus, anoints Jesus in his humanity[39] and thereby also becomes accommodated to humankind.[40] That the anointing of the Spirit has positive effects for the Spirit as well as for Jesus and humankind suggests that Irenaeus conceived of the Spirit as a divine person and not merely an impersonal force, and that the Spirit’s role is necessary for the transformation of humankind.[41] As Anthony Briggman argues, there are two benefits of the anointing at baptism: “First, the anointing of Jesus by the Spirit resulted in a non-qualitative empowerment of his humanity or the fulfillment of the christological mission. Second, Jesus’s anointing by the Spirit is the basis for the reception of salvation by the rest of the human race, for salvation comes to others by means of the Spirit as the unction of Jesus Christ.”[42]

For Irenaeus, there are two parallel tensions which are determinative for human salvation: 1) the immaturity of humanity that led to the “fall” versus the goal for humanity to be enabled and made worthy of seeing God face to face,[43] and 2) the disobedience of the primordial couple versus the need for obedience in transformation to god-likeness.[44] The latter ideal in each pair stands on one side of the “ontological gulf between the Creator and His creatures;”[45] so for humanity to attain to either the presence of God or the obedience upon which the former is requisite, God must be active to bring about the necessary transformation.

While this transformation is treated in christological terms, it is also robustly pneumatological. Christ gives the Spirit, but it is also the infusion of the Spirit that enables our union with Christ. For Christ, “uniting man to the Spirit and causing the Spirit to dwell in man, He is Himself made the head of the Spirit, and gives the Spirit to be the head of man, for it is by the Spirit that we see, hear, and speak.”[46] Obedience to God and transformation into a form able to withstand God’s presence are contingent upon union to Christ.

As was demonstrated above, Irenaeus sees union as a proper action of the Spirit; where humans are united, where the Word and flesh are united, and where humans are united to the Word, there the Spirit is discernible and active. It is only insofar as the Spirit is the power of the activity of creatures that they are able to respond in faithful obedience to the Father, thereby being made fit to behold the fullness (pleroma) of God face to face. This obedience that culminates in the perfecting of the person, for Irenaeus, “is gained by tuning into the dynamics of God’s economy with its trinitarian rhythm.”[47] It needs to be reiterated that this obedience is not merely a gracious response to what God has done, but, for Irenaeus, that persons are even capable of such obedience is evidence of the power of the Spirit working God’s love through them. Consequently, human obedience to God is a love-enabled activity and results in further transformation into Christ-likeness.

On their own and without the Spirit, humans are imperfect, both spiritually and physically.[48] The Spirit transforms humans, “not for the rejection of the flesh, but for the communion of the Spirit.”[49] Consequently, those who have been made spiritual are so thanks to the Spirit’s activity, not their own efforts and especially not because of a “suppression of the flesh.”[50] This is not, however, a merely eschatological and distant transformation; so Leahy:

Life in the Spirit is not, however, reserved for the final fulfillment of history in the kingdom of the Father, but becomes a present reality because the incarnate Son has given the Spirit to humanity. Assisted by the Spirit, it is in living the Word and receiving the Word that the ‘new’ self can inherit the Kingdom of God and put on the ‘nuptial garment’ of the works of justice.[51]

Finally, the unity of the Church, and the consistency of its preaching is due to the Spirit. It is because, “where the Church is, there is the Spirit of God; and where the Spirit of God is, there is the Church,” that believers in the Church “enjoy communion with Christ… the pledge of incorruption.”[52] This communion, empowered by the Spirit, is the opportunity of the Church to exist in a relationship of loving obedience with the Father. And this is participation in the triune God through the Spirit.


The Unity of God and Its Implications for Ontic Participation

“From the beginning to the end of his writings, Irenaeus declares the faith of the church in one father, one son and holy spirit.”[53] The unity of God is essential for Irenaeus and enables him to make several important theological points. First, the Father of Jesus and the God of Creation are not separate individuals but one and the same. Second, the work of salvation and creation are integrally connected.  Thus, the salvific work of God through Jesus and the Spirit fulfills the purpose of God’s work in and for Creation. Third, the unity of God is embodied in the unity of the Church, which is the Body of Christ, and its teachings.

The Gnostics argue that the God of Creation is evil, unlike the God of Salvation, which makes the Creation itself evil. Yet, for Irenaeus this does not compute because Jesus came in the flesh to restore all of Creation back to its intended purpose. In Jesus’ final moment on the cross, he breathes the Spirit into the Creation.  Everything is shaken and new creation has begun. Thus, the unity of God is necessary to fully comprehend Jesus’s birth, life, death, resurrection, and ascension.  Without the unity of God and God’s mission, the Church, and the apostolic teaching, the narrative of the Gospels lose their coherence and is opened up to any “spiritualized” interpretation.

            Irenaeus employs the image of the Two Hands of God working in the Creation to hold salvation and creation together as mutually compatible. It is the Spirit and Son working in unison with the Father in creation and salvation. In all things, Father, Son, and Spirit are working together, simultaneously to accomplish God’s purpose for Creation and humanity. Salvation is re-creation so that the entire Creation might once again be capable of God.

            It is through the activity of Father, Son, and Spirit in Creation that God is fully revealed.  Irenaeus states, “God the Father was shown forth through all these operations, with the Spirit working and the Son ministering, while the Father was approving – and that salvation for humankind was being achieved.”[54] This is important given the tension between God’s transcendence and immanence.

Gnostics held that God (Bythos) could not truly be known and that while the 30 paired Aeons which make up the Pleroma were divine, even they were not able to know God once more than one ‘projection’ out from him.[55] Irenaeus maintains God’s transcendence but also holds that God can be known because of the Son and the Spirit working in the Creation, like two hands in the soil.  It is also the Son’s flesh that reveals the invisible God in visible ways to humanity, even as bread, water, and wine are tangible symbols through which we might come to know and participate in the life of God. The Spirit enlivens these elements and through them makes Christ known.

When Irenaeus focuses separately on one of the Persons of the trinity for sake of clarification, there is always an immediate counter-movement reuniting them again. Remember, Irenaeus is concerned about God’s unity in juxtaposition to the Gnostic heresies. There is a constant tension that shows the continuity of God both in the old covenant and the new covenant.  As opposed to Gnostic thought, Irenaeus maintains that God is both God of Creation and God of salvation. 

For Irenaeus, creation and salvation are two sides of the same coin. One cannot exist without the other. What may be known about God is perceived through God’s activity in Creation (both in the creating and the saving of said Creation) by the Son and the Spirit. As mentioned previously, the Gnostics argue that God is unknowable, due to God’s transcendence. In this regard, Irenaeus responds:       

As to his greatness, it is not possible to know God, for it is impossible to measure the Father; but as to his love, which is what leads us to God by his Word when we obey him, we always learn that there is so great a God, and that he himself established, selected, adorned, and contains all things – including us and our world. We were made, along with those things which are contained by him. He is the one who Scripture says formed humankind by taking clay of the earth and breathing into his face the breath of life… God did not need… assistance to do what he had already determined to do, as if he needed hands. With him the Word and Wisdom, the Son and the Spirit, were always present, by whom and in whom he freely and spontaneously made all things – to whom he said, ‘Let us make humankind in our image, according to our likeness.’[56]

The connection for Irenaeus between creation and salvation, as well as, the overall unity of the Triune God is Love. Father, Son, and Spirit are a community whose Love is generative, both in creation and salvation. Creation and salvation are the generative overflow and desire within God to be in relationship with God’s Creation.

            The Incarnation is the major symbol of God’s fundamental movement toward humanity and Creation. Through the Incarnation Christ reveals God to humanity and recapitulates humanity through faithful obedience to the Father. Thus, Father comes to humanity by Christ through the Spirit so that through the Spirit and by Christ we might come to the Father.[57]

            It is important to state here that Irenaeus’s conception of the relationship of Father, Spirit, and Son is not hierarchal or modalistic. There is a relational mutuality inherent between Father, Son, and Spirit. The Triune God is One. Hierarchal or modalistic images of God create steps between the will of the Father and the action of the Son and Spirit.  There is no division between God’s willing and God’s acting. This creates far too much separation in God’s Person. God’s loving mutuality trumps any sense of rank within the Persons of God. The Two Hands of God does not communicate a power structure within the Godhead, but highlights the way God is visible and knowable to the Creation.  At the same time, it demonstrates Father, Son, and Spirit working together to restore, redeem, and re-create.

Irenaeus develops the thought of relationship as the purpose of Creation, writing, “The glory of God is a human being fully alive, and the life of a human being consists in beholding God.”[58] The problem is that it is impossible for humanity to behold God and live.  Only by God’s  grace is anyone capable of beholding God. Our participation in God’s life requires mediation. As such, the Incarnation unites God and humanity in Christ through the Spirit so that God and humanity might become accustomed to living together. The Incarnation becomes the vessel by which the fullness of God and the fullness of humanity dwell together.

So there is one God, who by the Word and Wisdom created and arranged all things.  This is the creator who has granted this world to the human race and who, as to his greatness, is unknown to all whom he has made – for no one has searched out his height, whether among the ancients who have gone to their rest or any of those who are now alive.  But in his love, he is always known through him by whose means he ordained all things.  This Word is our Lord Jesus Christ, who in the last times was made a human among humankind, so that he might join the end to the beginning – that is, humanity to God.[59]

Christ’s recapitulation enables and empowers our ontic participation. Christ takes on the fullness of humanity so that through Christ humanity might enjoy all of God.[60] Jesus becomes the second Adam by treading the same ground (recapitulation) that the first Adam tread but was found obedient, even unto death.[61] It is through Christ’s obedience that we see the fullest intentions and purpose of humanity! We are able, at every stage, to see what it means to be a fully mature human, living out our love for God through obedience: Christ![62] In this way, Christ is the example par excellence tangibly embodying the very life of God.

            Humanity’s purpose is found in God, which begins in Creation. Irenaeus unfolds his views on ontic participation as relational ontology, to use modern vernacular: “Without life it is impossible to live, and the means of life is found in fellowship with God. But fellowship with God is to know God and to enjoy his goodness.”[63] And, this fellowship of love is demonstrated as obedience, giving further weight to Christ’s recapitulating obedience. In other words, we were made for relationship, for community, and for union. Obedience is the grateful response to Christ’s invitation to participate in the life of Father, Spirit, and Son.

Interestingly, Irenaeus’s perception of the Incarnation is not contingent upon humanity’s failure to live in faithful obedience. Rather, the Incarnation was intended before the Creation.[64] The purpose of Creation from the beginning was to enjoy fellowship with God! This shapes the understanding of the Incarnation and the cross in significant ways that push back on penal substitution so popular in contemporary churches, especially where it seems to put Son and Father in contention.

The Incarnation undermines the Gnostic idea that Creation is bad and spirit is pure. It is all a creation of God, who is good. Furthermore, the Incarnation challenges any separation of Christ’s work from the purposes of the Creator. After all, if Christ did not come in the flesh, God is deceptive and does not fully know or understand our plight. Yet, Jesus did come in the flesh. By this, God affirms the value of Creation and is included in God’s redemption of the Creation.

The prospect of “divinization” has been troublesome for many.  John Lawson holds, “To teach that man is saved by becoming a ‘partaker in the divine nature’ (2 Peter 14) is a legitimate expression, so long as pagan pantheism is firmly excluded by a sound Biblical doctrine of God. The general proposition of ‘divinization’ is not to be rejected.”[65] Lawson’s concern about taking “divinization” too far is warranted. Irenaeus does not intend to say that ontic participation dissolves us of our identities as creatures. Love does not strip us of our unique identities. Rather, our identities are maintained while facilitating ontic participation with the other. Irenaeus employs nuptial theology as a metaphor for union with God. Becoming one flesh does not dissolve us into the other. Instead, diversity and unity are held in creative tension.   

Rather, our humanity becomes full and complete through union with God. Irenaeus frames it this way: “For while God is always the same, man when found in God will always advance towards God.”[66] God is the one who creates while humanity remains the created. And, all of Creation is caught up in the work of salvation, which includes both spirit and flesh. Theosis, recapitulation, and ontic participation are holistic concepts that swallow up the corruptible with the incorruptible, the mortal with the immortal.

            Humanity was created in the image and likeness of God.  Irenaeus suggests that the image and the likeness are distinct aspects of what it means to be human.  The image is something that is damaged but it is still retained in every human. It is a reflection of Christ, in whose image we are shaped. This image includes our flesh. The likeness is what is lost due to our disobedience. The likeness is the capacity for God. Christ re-constitutes that likeness through his obedience and makes it possible for humanity to once again enjoy God in fellowship, which is at the very heart of what it means to be human.[67] The Spirit empowers and cultivates in humans the love necessary for obedience, through which we are transformed into the likeness of Christ to the glory of the Father. This basic trinitarian movement exemplified in Christ’s Spirit-empowered ministry is extended to include humans, so that they might also join the loving acts of God for the transformation of the cosmos.


Irenaeus’s Contribution for Wesleyan Concepts of Holiness

            Holiness, in many ways, is deeply connected with ontic participation. Love is the heart of holiness. When using language of holiness or entire sanctification or perfection, we are not saying that we become God or that we cease to continue moving toward God. Rather, Irenaeus reminds us, “For while God is always the same, man when found in God will always advance towards God.”[68] Holiness is about becoming fully human, maturing in and toward Christlikeness! It is to become by grace what God is by nature.

            God alone is the One who is Holy. Our holiness is derivative of God’s holiness.  Sanctification, the process of being made holy, is the work of Christ and the Spirit restoring the image and likeness of God in us, which begins at justification. Holiness is the process whereby we are growing in maturity towards Christ, who is our recapitulation. And, it is through Christ’s obedience that we are enabled and empowered to be obedient through covenantal love.  

            Like the Gnostics, we also have a tendency to think of holiness only in terms of the spiritual. In other words, we neglect the incarnational aspects of holiness. But, again, we must remember that God’s work, as seen in the Incarnation, is holistic.  It includes both flesh and spirit. Because there is no true separation in us, we are both breath and dust, spirit and flesh, in order to be totally saved and made holy, it must include both aspects of our humanity. Holiness is not a ticket to some far-off, disembodied heaven. It is a call to embodied existence that reflects the character and nature of God back into the world. After all, the resurrection was an embodied resurrection, which we too shall enjoy.

            This brings us to John Wesley’s communal conception of holiness: You cannot have personal holiness without social holiness.[69] It is not solitary religion; it is a social faith (which does not exclude the personal aspect of faith). Christ recapitulates humanity, not merely each individual. Holiness includes the very flesh-and-bone realities of everyday living in community. It necessarily includes tangible obedience that demonstrates God’s love for us by loving our neighbors. It is important to remember that holiness is not merely about separation. It inevitably includes unity in community. As holiness people, we are constantly living in the tension of redemptive engagement and prophetic disengagement. But, even as we wrestle with that tension, we must remember that schism is a breach of love because it violates the very character and nature of God, who is One. Jesus teaches his disciples the Lord’s Prayer which points to the reality of heaven and earth being united, where God’s will is perfectly done, not only in “heaven” but in this physical world. Holiness calls us to live into that future as if it is already established.

            Holiness should be understood as relationship and fellowship. If the Incarnation was planned from the beginning, not caused by our disobedience, then the whole purpose of Creation is relating with and to the Creator. Our end is in our beginning. Holiness is the capacity for relationship with God. Without holiness no person sees God.  Participating in Christ’s righteousness (right relatedness) through loving obedience, we are once again restored to the capacity for knowing and seeing God and living in right relationship with God, others, and Creation.

And, if holiness is also a process of maturing, there is the potential for the exact opposite as well. God is not coercive. Love is not coercive. If love and relationship are coerced, then it is not true relationship. As such, holiness requires our active participation. We must respond to God’s invitation to love and to be in relationship. Son and Spirit empower us to respond, but they do not force us to respond.

Holiness is God’s work entirely, which we are invited to receive and partake, but we are never forced to take that gift. The content of holiness is not obedience merely to a moral code; it is love. That is why the heart of obedience is doxology, which is love. Obedience is the praise-filled response to God’s invitation to live empowered by the Holy Spirit, through Christ, and to the Father as reflections of God’s character and nature – which is Loving Community.


Can creation participate in God? This is the question that we have brought to Irenaeus and have heard a rich and resounding “yes” throughout his writings. In contrast to the “Gnostics,” Irenaeus tells us that participation is not merely “spiritual” nor noetic, neither is it something that some humans are capable of and others not. Rather, participation is made possible by the unity of God present to creation through God’s “Two Hands.” We have argued that each of the Two Hands of God have particular roles in bringing humanity to participate in God. Through recapitulation, Christ accommodated humanity to God through his obedience; so now humans are capable of the divine. By anointing Jesus’ at his baptism and humanity in their baptisms, the Spirit has accommodated the divine to humanity; the Spirit enables the obedience necessary to share in the new creation with Christ.

These unique acts of the Two Hands of God are not isolated or binitarian, they are the acts by which we come to know and share the life of the Triune God. This is the plan that the invisible God has intended from the beginning of creation and is brought to fulfillment and made visible in Jesus Christ. We have had the opportunity to compare Irenaeus’s understanding of atonement and divinization to some shortcomings in the Holiness Movement while also affirming Wesleyan conceptions of sanctification. By looking more closely at the unified conception of creation and redemption in Irenaeus, richer options are available to our denomination as it develops its practice and theology of sanctification.

[2] We must be cautious in how explicitly we discuss the presence of trinitarian theology in Irenaeus. Given his chronological distance from Nicaea and Constantinople, it amounts to little more than anachronism to claim anything more than that we can identify the roots of trinitarian theology in Irenaeus, much like what we find in scripture. Having said this, it must be admitted that a remarkably trinitarian picture appears in the Chapters 6 and 7 of Irenaeus’s Demonstration of the Apostolic Preaching as he lays out the “three articles” which are “the plan of our faith, the foundation of the building and the glue of our way of life.” See Jack N.

[24] It needs to be clarified that obedience is first and foremost a characteristic of the relationship of love shared between Christ (the Son) and the Father. It is not mere subordination or passive acceptance of a domineering father’s wishes; Irenaeus sees the Word and Wisdom – the two hands of God – as the intimate work of God within the good creation, consequently Christ’s obedience is the human counterpart (christologically speaking) of God’s intimate work in creation. When obedience is secondarily granted to humans, it is an extending of the filial relations between Father and Son through the love and power of the Holy Spirit. That humans can act obediently in Christ-like manner is a consequence of the person’s very being becoming a “partaker in the divine nature.”

[37] Two things are interesting in this regard: 1) that he assumes that the reader will understand the human body and spirit’s unity on analogy with that of the Eucharistic elements in some way suggests that the type of union he is articulating was commonly accepted and already understood in the context of the sacraments; and 2) Irenaeus does not explicitly say that these things are by the agency of the Spirit in this particular passage. Nonetheless, it seems plausible that he would agree with my reading him this way because i) the uses of capital “S” for the human spirit, which seems to suggest a connection between the unity of our body and spirit with the unifying activity of the divine Spirit, and ii) because unity (albeit between persons) has already been attributed to the Spirit’s working and is now being extended to the Spirit within a person’s life. 

[38] This is important to note because the typical modern reading of human body and spirit would be strongly dualistic. Irenaeus is actually arguing for stronger unity between body and soul in contrast to the sharp distinction the gnostics make between the two. Further, that the soul/spirit itself has no intrinsic immortality and will not outlast the body is notable in contrast to modern Christian thinking (at least on the popular level) that would tend to look more like Gnosticism than Irenaeus in this debate, arguing for an abandonment of the body for the liberation of the soul to a non-physical heavenly paradise.

The Biblical Theology of Saint Irenaeus by John Lawson

Lawson begins by tracing some of the popular ways that Irenaeus has been interpreted by more modern scholars, specifically as understood by Ludwig Duncker and Paul Beuzert.  Lawson’s argument that Irenaeus is not a systematic theologian is accurate, contra Duncker.  Irenaeus should be considered more a biblical theologian.  “The systematization is something that has to be brought to him” (12). 

The purpose of Lawson’s book is best understood as a response to Beuzert’s reading of Irenaeus.  He highlights seven areas of contention: 1) Beuzert limits the scope of the Two Hands of God to the creation of humanity 2) Irenaeus’ concept of Trinity is not necessarily an Economic Trinity 3) Beuzert believes that Irenaeus’ lack of “substitutionary or satisfactory” atonement theory makes him “un-Pauline” 4) Beuzert’s rendering of “saving faith in Irenaeus is far from just” 5) Paul’s influence on Irenaeus is “unduly minimized” 6) It is anachronistic to categorize Irenaeus as Western.  His interest in the authority of the Church is “dogmatic orthodoxy, not in centralized organizational discipline” 7) Irenaeus was more concerned about outlining the parameters of faith, not being intolerant.  I think Lawson is largely right to push back on Beuzert’s anachronistic reading of Irenaeus.  Denis Minns and others have expressed similar sentiments in their writings on Irenaeus.

Irenaeus, without a doubt, considers the Scriptures to be inspired and authoritative for the life of disciples.  However, as Lawson points out, this does not then mean that Irenaeus has a clearly defined understanding of “how” it is inspired.  Ironically, Lawson then says that Irenaeus would likely be a “Literal Inspiration” proponent.  Based on his initial argument, this does not make sense.  One could make an argument that Irenaeus’ understanding of inspiration is based on the gift of the Holy Spirit, rather than a “Literal Inspiration” due to Irenaeus’ theology of baptism.  After all, Irenaeus points out that the Rule of Faith is inherited in that moment of regeneration!   As per Irenaeus: Life, Scripture, Legacy, Irenaeus believes that what is needed for correct interpretation is received in the moment of baptism when the Spirit descends upon that person.  In other words, simply having the right words is not enough (the Gnostics have a number of the same Scriptures that they misuse!). 

Furthermore, the emphasis of Scripture is not yet on the canonicity of the words as it is about the apostolicity of the words.  There is still a degree of the oral tradition, which Irenaeus is just barely getting in on through Polycarp, being taught and handed down.  Irenaeus then points to those that do not have those written Scriptures yet live obediently through the traditions that have been handed down!  As such, I find Lawson’s conjecture highly speculative and unfounded.

Lawson also assumes that a literary work becomes Scripture “on account of their authorship” (33).  I think this is rather naïve.  It’s not on account of authorship as much as it is on account of the community that receives the work as authoritative and connected to the tradition of the apostles.  After all, several works have no author named.  If “authorship” was so vital, it would make sense that an author would have been named to begin with or that the author’s name would not have slipped from memory!  Granted, apostolic authority was important for the early Church community, but that does not explain the Old Testament autographs that lack a named author.  At the very least, it is imperative to realize that it is not merely the authorship that provides authority but the community that recognizes and attests to the validity of the text and its authority for the community!  That’s not to say that authorship is unimportant but it is not the only criteria.

In trying to uncover Irenaeus’ source of authority, Lawson suggests several things that I find difficult.  First, he suggests that Irenaeus believes “charismatic prophecy” to be a source of authority.  I wish this had been further defined.  If Lawson means that it is a “gift of truth-telling” then it seems much more legitimate than a “spiritualized ecstasy of future-telling.”  It seems that prophecy should be understood more as forth-telling than fore-telling. 

Secondly, Lawson says that “Reason” is not a seat of authority and then proceeds to define Reason as “postulated ideals and inherent probabilities… abstract think[ing].”  I think this is a very shallow understanding of Reason’s position in Irenaeus’ work.  It is a seat of authority, as long as it is testified to by the Church and empowered by the Holy Spirit.  Reason is not merely “abstract” thinking.  In fact, I would suggest that true Reason is practical and must be tested in the crucible of life.  Or, maybe as Irenaeus might say – incarnated.

Lawson also contests an Economic Trinitarian reading of Irenaeus.  In fact, he suggests that Irenaeus is not subordinationist or modalist in his conception of Trinity.  Rather, Irenaeus understands that where one Person of the Trinity acts, there acts all three Persons of the Trinity simultaneously.  Thus, the “Two Hands of God” are not ways of talking about God in hierarchal, positional, or functional catagories.  Instead, the Father, Spirit, and Son are all working in conjunction with one another to create, sustain, and bless.  Separate the activity of the Persons of the Trinity is to fall into tritheism.   

Lawson also has an unwarranted view of science and history.  It is a modernist conception that takes on the air of humanism.  He states that Irenaeus’ use of the Old Testament is lacking because he does not know or does not have the history available to him.  However, it seems haughty to think that after two thousand years separating us from that time we might know and understand more completely than Irenaeus.  Furthermore, it suggests that humanity and human knowledge is constantly progressing.  Information may be more available but that does not then mean that wisdom has increased.  Granted, Irenaeus does use Scripture out of context at moments.  However, that does not mean that he is unaware of history.

Lawson points out that Irenaeus talks frequently about “divinization.”  Lawson states that this is not objectionable “provided that it be borne in mind that they describe only a single aspect of salvation, i.e. the intellectual.”  However, this does not seem to be Irenaeus’ conviction.  Instead, it is to be understood as holistic.  However, I don’t think Irenaeus would conclude that we are somehow dissolved and that we cease to be human.  Rather, our humanity becomes full and complete in this union with God.   

Christus Victor holds great potential for discussing God’s atoning work.  “Going over the same ground” frames Christ’s life and ministry in promising light, especially in regards to penal substitution.  Although Lawson does not argue this directly, Irenaeus’ concept of the Trinity working together simultaneously in everything prevents us from reading a strictly penal substitution theory of atonement (for it suggests that the Father and the Son may even be at odds with one another)!  Moreover, as Lawson suggests, it may be better to think of these atonement theories as metaphors that describe the significance of what Christ has done, not detailed exegesis of how it was accomplished.

Overall, this was a good book that challenged some of the popular academic assumptions of that day.  This is helpful given that many of these assumptions are still alive today.  Lawson provides great insight into the significance of Irenaeus’ Biblical theology and his significance for the Church.  However, Lawson makes several assumptions that reflect modernism more than they reflect Irenaeus.  Irenaeus is awkwardly crammed into modernist categories that are far too anachronistic to apply.  This is the real weakness of this book.  With careful reading these can often be weeded out and measured for their overall worth.        

Irenaeus of Lyons by Eric Osborn

Eric Osborn notes the general difficulty for scholars reading Irenaeus.  This difficulty has often led scholars to brush Irenaeus aside as someone that has poor logic and arguments.  Osborn, however, contends that this is a misunderstanding of Irenaeus’ language, criteria, and concepts which compose his arguments against the Gnostics.  Plus, he supposes that a great deal of this attitude stems from the Modernist empathy toward the Gnostic agenda (i.e., the emphasis on mind and knowledge).  Thus, Osborn will attempt to uncover Irenaeus’ logic and aesthetic argument against Gnosticism.

            Osborn’s preface states, “Here Irenaeus follows Justin but with wider vision, for he is the first writer to have a Christian bible before him” (xi).  Osborn should clarify what he means by this statement.  Left unexplained, it sounds like Irenaeus had a fully formed canon.  However, this is anachronistic.  The canon is not finally formed until two centuries after Irenaeus’ death.  John Lawson makes a similar assumption in his assessment of Irenaeus as a biblical theologian.  That is not to say that Irenaeus doesn’t employ those texts, but it is not fully formed yet.  Plus, Irenaeus makes use of extra-biblical sources; he doesn’t only use the “Christian bible.”  It is not until several chapters later that Osborn qualifies his statement.

            Osborn makes a similar claim in his chapter: “Logic and the rule of truth.”  For instance, he writes, “Strictly, the compact body… of truth, in contrast to the fabrication… of the heretics, refers not to a written source but to absolute truth.  There is only one message of salvation and one reconciliation wrought in Christ incarnate.  The rule joins bible and tradition” (145).  I think there needs to be more caution in talking about “absolute truth” without distinction.  Is this remnant of modernist philosophy?  Is Osborn referring to some kind of natural law?  If so, this poses certain problems with Irenaeus’ vision of God. 

Also, Osborn makes a weird distinction between bible and tradition.  As argued above, the bible is not fully formed yet but the Scriptures are the tradition and the tradition is Christ!  The rule does not join what is already joined.  It testifies to that which has been handed down from Christ and the apostles!

            Osborn does finally say that the bible was not a fully formed document in Irenaeus’ day.  However, he still makes a problematic statement when he writes, “The bible is the highest source of truth because the prophets were inspired of God.”  Irenaeus did not say it in this way!  The highest source of truth was Christ.  Scripture was deemed authoritative for the community because it accurately testifies to who Christ is!  Osborn seems to talk out of both sides of his mouth on this point.  It is important to remember, as Osborn states, that the Gnostics also employed the Scriptures as their proofs!  Yet, Irenaeus deems their interpretations as false because they do not conform with the measure of truth, which is Christ! 

            Osborn did a great job of illustrating Irenaeus’ concern for the unity of God.  Irenaeus is trying to show that God demonstrated in Christ Jesus is the same God that created the world.  Thus, the unity of God is vital.  When the Persons of the Trinity are discussed separately, it is only for the benefit of understanding.  All should be thought to act together, simultaneously, and in coherence with one another.  To lose this connection is to also diminish the work of Christ.

            This unity applies not only to the three Persons of the Trinity.  For instance, what God thinks, God wills, and God acts simultaneously.  God does not act in stages.  This is important for the overall unity and cohesion of the Triune God: Father, Spirit, and Son.

            This unity spills out into other parts of Irenaeus’ theology.  Because God is One, so too is the Church.  The Church is unified by the fact that it is unified by the apostolic succession, which is the teaching of the apostles concerning Christ.  That is the tradition that has been handed down and to which Irenaeus refers in providing a succession list of Rome.  The Church speaks as if it “had one mouth.”  Thus, as a reflection of the Triune God, the Church is also One.

            Osborn understands Recapitulation to be “correction and perfection.”  I think this is an appropriate way to frame Irenaeus’ concept.  First, Jesus becomes human to embody what humanity was intended to be in the first Adam.  As the Second Adam, Christ lives in faithful obedience, even unto death.  Thus, as sin entered the world through Adam, Eve, and tree, so now that would be reversed through Jesus, Mary, and the cross.  Not only does Jesus provide a corrective, but by becoming all that humanity is, all that God is becomes fully available to humanity. 

            This is a necessary step in Irenaeus’ understanding of human maturation.  God and humanity must become accustomed to living with one another.  In Christ, God and humanity are held together.  Through this, God is shown to be the “wise architect and sovereign king” of creation and salvation.  Although God is transcendent and hidden, it is through the Two Hands of God working, shaping, molding in the creation that God is made known through Love in the world.  God desires “union and communion” with that which God creates.

Now, it is vital to understand that this does not mean we become God, as some have claimed or misunderstood.  God remains the One who creates while we remain the ones who are created.  God is holy; we are made holy.  In other words, we participate in the life of God but do not take God’s place.  We are joined through Christ into the very life of God.  In this sense, we become fully human and fully alive.  This is the glory of God, according to Irenaeus.  Or, as Irenaeus puts it, “For while God is always the same, man when found in God will always advance towards God” (43).

Another helpful concept that Osborn dealt with was the distinction between likeness and image.  Image is something that everyone retains, while likeness is something that must be restored.  The image deals with the flesh.  Likeness refers more to the part of restoration that is accomplished by the Spirit. 

Overall, I thought Osborn’s book offered some valuable insight.  He wrestled with issues that other authors we have read did not attempt to address.  In this sense, he was very helpful.  However, Osborn also had moments where he was very poor in defining what he meant by terms.  For instance, Osborn talks about Irenaeus as a biblicist.  Due to the nature of that kind of language, it is difficult to assess what he means by this term.  Does he mean Irenaeus’ is dependent upon the Scriptures in his theology or does he intend to say that Irenaeus is a fundamentalist in interpretation of the scripture… or something else?  As such, Osborn is sometimes difficult to pin down what exactly he is trying to push.

James Payton’s purpose in writing this book is to make Irenaeus’ Against Heresies more accessible and less cumbersome to engage.  His primary method for achieving this end is shortening Books 1 and 2, which sets out the Gnostic doctrine as it is taught.  Although large sections are removed from these two books, enough is left to provide a brief and succinct overview of the Gnostic thought and Irenaeus’ primary objections to it.  Payton does a good job of maintaining the key ideas in Irenaeus’ assessment of the Gnostics while presenting an abridged version.

Irenaeus is often described as a polemical figure.  Undoubtedly, he tackles the Gnostic problem head on without much reservation.  However, it should be noted, by Irenaeus’ own words, that this is not the primary motivation.  Irenaeus is polemical only in the sense that he is trying to preserve something.  Irenaeus describes the situation with his opponents as such: “This is how the adversaries with whom we have to deal act: like slippery serpents, they try to escape at all points.  Consequently, they need to be opposed at all points, so that possibly, by cutting off their retreat, we may succeed in turning them back to the truth” (57).  The preservation and proclamation of the Truth is at the heart of Irenaeus’ purpose in writing.  As such, he hopes that by writing even the Gnostics might come to know Truth that has been handed down from Christ to the apostles for the Church.

After reading the way that Irenaeus re-orients the Old Testament in light of Christ, I find John Lawson’s categories for Irenaeus untenable.  Lawson states that Irenaeus did not know or adequately comprehend the history behind the Old Testament.  However, I believe that Irenaeus has a rich understanding of the Old Testament, which he reads in light of Christ.  He does not read the Old Testament in isolation from its preparation for Christ.  Thus, the importance does not sit upon the historical context but on the way that Christ fulfills and completes that which is in the Old Testament.  For instance, Irenaeus re-functions the Old Testament texts that talk about swords being beaten into plowshares to bring about a fuller comprehension of the cross.  An instrument intended for violence becomes God’s instrument of peace through which the harvest of the eschaton will be gathered.  Irenaeus does not ignore the historical context but says that the purpose is realized in Christ.

This is essential for Irenaeus’ argument against Gnosticism.  After all, Irenaeus wants to maintain the continuity between Jesus and the Creator God of the Old Testament.  What better way to do that than showing how Christ corrects and fulfills the Law and the Prophets.  Irenaeus is not allegorizing every Scripture and twisting it.  Rather, his exegesis is quite stunning in many respects.  For instance, Irenaeus employs the stories of the patriarchs in appropriate ways to the promised hope that is embodied in Jesus.

Recapitulation or ontic participation is scattered all throughout Irenaeus’ writings.  Although they are slightly different, they cannot be separated from one another.  Christ takes on the fullness of humanity so that through Christ humanity might enjoy all of God.  Jesus becomes the second Adam by treading the same ground that Adam tread but was found obedient, even unto death.  And, it is through Christ’s obedience that we see the fullest intentions and purpose of humanity!  We are able, at every stage, to see what it means to be a fully mature human: Christ!  In this way, Christ is the exemplar of what it means to participate in the very life of God.  In fact, Irenaeus states: “The glory of God is a human being fully alive” (116).

The main purpose for Irenaeus in salvation or recapitulation is that humanity might finally achieve its end: “join[ing] the end to the beginning – that is, humanity to God” (114).  He also views ontic participation as a relational ontology (to use modern vernacular), stating: “Without life it is impossible to live, and the means of life is found in fellowship with God.  But fellowship with God is to know God and to enjoy his goodness” (115).  And, this fellowship of love is demonstrated as obedience.  Which highlights the value of Christ’s recapitulating obedience.

Irenaeus’ concept of the Triune God working simultaneously and spontaneously together is intriguing.  We can learn a lot from him here.  In all ways, the Father, Son, and Spirit are working in unison and cooperation toward a common telos.  There is not a true sense of hierarchy or modalism that pervades the Trinity.  Instead, there is a relational mutuality that is inherent in God.  Now, Irenaeus typically talks about the “Two Hands of God” (Son and Spirit, Word and Wisdom).  However, by separating these out, Irenaeus only moves to put them back together again.  There is a constant tension that shows the continuity of God both in the old covenant and the new covenant.  As opposed to Gnostic thought, Irenaeus maintains that God is both God of Creation and God of salvation.

In fact, it is only through this cooperation that God is fully revealed.  He states, “God the Father was shown forth through all these operations, with the Spirit working and the Son ministering, while the Father was approving – and that salvation for humankind was being achieved” (115).  This is important given the tension between God’s transcendence and immanence.  Gnostics held that God could not truly be known and that the Pleroma were not God.  Irenaeus maintains God’s transcendence but maintains that God can be known because of the Son and the Spirit.  Most specifically, it is the Son’s flesh that reveals the invisible God in visible ways to humanity.  This is a brilliant tactic in dispelling his opponents’ arguments.

I particularly found Irenaeus’ concepts of recapitulation and ontic participation refreshing.  His emphasis that the Incarnation was going to happen even before the Fall, not because of it, was powerful.  The purpose of Creation from the beginning was to enjoy fellowship with God.  This shapes the understanding of the cross in significant ways that push back on the penal substitution so popular in our churches.  It pushes back on the Gnostic idea that Creation is bad and spirit is pure.  And, it challenges our separation of Christ’s work from the purposes of the Creator.  Our end is in our beginning.  Creation is salvation and salvation is creation, because it is God that works both.

“Irenaeus: Life, Scripture, Legacy” by Sara Parvis and Paul Foster

            One of Irenaeus’ themes that piqued my interest is the idea of human freedom.  According to Irenaeus, evil came from decisions made or not made.   This play in human freedom is an interesting one given Irenaeus’ theology of ontic participation.  What I find most compelling by this human freedom to will is the notion of a relational ontology.  Salvation is not merely getting rid of the human nature.  Rather, it is restoring it to proper relationship in which we are able to participate in the divine life through Christ (having been clothed in the Holy Spirit).  It is for freedom that Christ has set us free.  To be sinful is to be enslaved.  

Sophie Cartwright tries to argue that Irenaeus actually gives up human independence or autonomy because of his comprehension of ontological participation as relationship.  I disagree.  Dependence does not mean loss of freedom, as Cartwright states it.  Irenaeus’ conception of the Spirit in the life of humanity does not then make us automatons.  In fact, there is great freedom, true freedom, within the boundaries of God’s life-giving creation!  As in a marriage relationship, dependence does not then mean that we cannot make genuine choices, both for good or ill.  There is freedom within the relationship.  To step outside of those bounds, however, does impact the relationship.  I do not think a Calvinistic understanding of determinism works well with Irenaeus’ depiction of the Spirit indwelling humanity.  

            Karl Shuve made a solid argument that Irenaeus’ nuptial theology shaped the groundwork for a more allegorical understanding of the Song of Songs.  This nuptial theology, supposedly, opens up a framework to understand the Song of Solomon as an allegory for the union of Christ and the Church.  Although it is quite possible to assume that Irenaeus may have contributed to this kind of reading, it is difficult to say that it originated or was even made popular by Irenaeus.  Remember, after all, Irenaeus was not keen on being novel but merely representing truth consistent with the apostles’ teaching.  That being said, it is quite possible, maybe even probable, that a nuptial theology pre-dates Irenaeus significantly.  After all, the New Testament has already made that move and opened the door for such interpretations to be made.  And, it may be that nuptial theology was already in existence as a Jewish interpretation of things like Song of Solomon.  Jesus own use of nuptial theology might suggest this is the lingua franca prior to Irenaeus.

            Charles Hill’s response to Moll was the strongest argument for the identity of the “Elder” in Against the Heresies.  Hill makes a very strong and cogent argument based on the use of “pais” to indicate Irenaeus’ age when he was learning from the presbyter that learned from the disciples.  I believe there was adequate evidence to show that “pais” may extend into one’s teenage years or beyond.  Irenaeus may have known Polycarp at an age that he could have retained, especially with repeated hearings, Polycarp’s teachings.  Also, in regards to age, it does seem strange that Irenaeus, if he was too young to remember these encounter(s), would be aware or concerned about Florinus’ motivations for being in the “royal court.”  This does seem to be a concern more for those that are preparing or are already a part of the public life in this manner.

There was also significant connection made between Polycarp being mentioned early in Against the Heresies while only being referred to as the Presbyter or Elder later in the same work.  This, to me, signifies a mark of humility.  If Irenaeus has already mentioned Polycarp, he does not need to continue to name drop, so to speak.  Irenaeus’ audience would have known the connection.  I also concur with Hill that Moll’s reading of Irenaeus is one of suspicion from the start.  Why is it that Irenaeus is faithful or truthful in other parts, except when it comes to his knowing Polycarp, by his own admission?  This seems strange, as Hill points out.  Overall, I found Moll’s thesis unsatisfying.   

            Slusser makes a case for magnitudo and dilectio as the “heart of Irenaeus’ theology” versus recapitulation.  I would venture to say that these are definitely a part of Irenaeus’ theology, as per Slusser.  They even play important roles in Irenaeus’ apologetic.  However, I think that there is an artificial/superficial line that Slusser uses to separate these two from recapitulation.  Undoubtedly, God’s love is what ultimately allows humanity to truly “know” God, despite God’s magnitudo.  Recapitulation is the way that love is expressed!  Slusser makes the effort to dissect Irenaeus’ conception of God’s love without fully realizing that Irenaeus is constructing a theology that is holistic, not merely emphasizing one part of the economy of God’s salvation.  Another way to say it is that Recapitulation is the bridge between magnitudo and dilectio.  Irenaeus’ view of ontic participation, which has everything to do with God’s character as Holy-Love, is at the very heart and center of his theology.  What I appreciate about Slusser’s approach, although it sounds much more like Luther’s mysterium tremendum, is that it highlights the significant need for recapitulation.  The chasm between God and humanity can only be re-connected by a fundamental movement of God toward humanity.  That is recapitulation; that is love!

            It is often suggested that the attraction toward Gnosticism for women is in direct correlation with a revolt or repulsion to the paternalism of Christianity and Judaism.  Sara Parvis makes a brilliant counter-argument that shows Irenaeus’ theology is actually quite open and appreciative of women… even more than Gnosticism!  Irenaeus’ Marion theology as recapitulation of Eve is probably the strongest argument for Parvis’ case.  Parvis adequately demonstrates Marcus’ form of Gnosticism is manipulative and exploitative of females.  Within the Gnostic framework, women are still blamed for evil or are lesser than the male gods.  Yet, Irenaeus’ is able to highlight God’s female attributes (i.e., breasts of comfort).  Furthermore, he seems to be quite comfortable with women playing a significant role in worship (i.e., prophesying). 

I think Irenaeus’ Marion theology actually challenges Gnostic scholars’ assumption concerning women in Christianity.  Although sin comes through Eve, salvation comes through Mary because it is by her that Christ receives the fullness of humanity.  I wish Parvis had articulated Irenaeus’ nuptial theology as a fuller supplement to her argument.  She touches on it briefly, but it would have been tremendous to connect the Church as bride of Christ in a fuller way.  The whole of redeemed humanity, the Church, is described through female imagery.  It is positive imagery!

Overall, this is a good book.  There were articles in it that I found less than helpful or interesting.  But, other articles were great insights into Irenaeus’ contribution to the Church.

Irenaeus: An Introduction by Denis Minns

            Dennis Minns sets out a brief introduction of Irenaeus by following his polemical arguments in Against Heresies.  This document is Irenaeus’ refutation of the Gnostic tradition  as espoused by Valentinus, as well as, the Marcionites, who differentiated between the God of the Old Testament and the God of Jesus, as per Marcion.  By following Irenaeus’ arguments, Minns hopes to establish the ancient writer’s overarching theology, even though it far from a systematic work.  Minns uses this approach for Irenaeus since much of his biography is unknown and speculative at best.

            Due to the limited information concerning Irenaeus’ life, Minns suggests that Irenaeus must be understood in light of his polemic.  In other words, Irenaeus’ theology is forged in response to the “heretics” of the early Church.  Although Irenaeus does respond to the Gnostic problem, it is difficult to imagine this then qualifies him solely as a “polemical theologian.”  This label suggests his theology is merely response and reaction.  Plus, it suggests that it is entirely negative (i.e., “it is not this but this”).  I find this a difficult category to adequately contain the whole of Irenaeus’ work and legacy for the Church.  After all, Irenaeus helped form the canon and the regula fidei as guides for the Church.

We should remember that Irenaeus’ theology was formed under the tutelage of Polycarp long before Against Heresies was written.  In other words, Irenaeus’ theology is well-formed by the time he actually set out to respond to the Gnostics.  Furthermore, with so little knowledge about Irenaeus’ total life, it may be unfair to label him solely as a “polemical theologian” based on his limited writings.  As a “man of peace”, it could be that Irenaeus was much more than a “polemical theologian.”  In fact, Irenaeus’ “polemic response” may be more out of concern for unity than orthodoxy (although right doctrine is important).

            Irenaeus’ primary concern in Against Heresies is combating the false doctrine of Gnosticism.  Gnostics bifurcated all of life into spirit and flesh.  The body and everything material was considered evil and corrupted.  The spirit, on the other hand, was considered pure and good.  Those that had received special revelation were given the ability to transcend the material and would inherit eternal life in a disembodied heaven.  Irenaeus’ theological response to this issue is a great contribution to the Church.  We are both “dust and spirit or breath.”  We are both physical and spiritual creatures.  We cannot be human without both of those present.    

            Irenaeus outright rejects the Gnostic notion for several reasons.  His most powerful arguments center on the fact that to be human is to be embodied and part of the material world, despite its broken state.  We are all the progeny of the first Adam because we have been molded from the same mud by God’s hand.  Furthermore, God’s economy of salvation is established and completed in the work of Christ who is the second Adam.  Through Christ we participate in the new life of resurrection, which will be a bodily resurrection. 

The grace of God available through the sacraments of the Church attests this bodily redemption.  Baptism cleanses the body and the Eucharist allows us to receive Christ’s body into our own bodies.  By being joined with the glorified body of Christ, our bodies, too, are glorified by the Father.  Irenaeus employs the Scriptural notion of “recapitulation” to describe this reality.  Christ’s participation in our humanity makes way for our participation in his glorification.

            Marcion believed that the Creator God of the Old Testament was different than the loving God that Jesus claimed as Father.  As such, Marcion omitted the Old Testament and heavily redacted the New Testament in light of this conviction.  Conflicting views in the New Testament were harmonized or done away with altogether.  This violates Jesus’ own words that he came “to fulfill the Law and the Prophets.”  John’s Gospel, which was also popular among the Gnostics, connects the Logos (Christ) with the Creator God of Genesis 1.    

            Again, Irenaeus went to task against Marcion’s understanding.  Irenaeus integrally linked the economy of creation and salvation together.  Thus, the first creation is fundamentally a part of the new creation that will be ushered in with the New Jerusalem.  God’s Creation was created “good” not evil.  In other words, the work of the Creator God in the Old Testament cannot be separated from the work of Jesus’ Father in the New Testament.  Irenaeus will go on to point out that there is only One True God in Three Persons.   

There are not two gods, as the Gnostics and the Marcionites suggest.  Rather, there is only the One True God whose image is Christ.  Although Irenaeus tends to emphasize Jesus’ humanity, he does not do so to the detriment of Jesus’ relationship as Son to the Father.  Jesus is divine as well as human.  He is conceived by the Holy Spirit and born of the same mud as Adam through Mary.  This is an essential response to particular forms of Gnosticism, especially under Marcion, that conceived of as Jesus being fully human but adopted as God’s son.  Irenaeus holds Jesus’ humanity and divinity in full tension. 

Thus, in Christ both divinity and humanity are brought together.  Recapitulation of Christ as the second Adam bridges the gap between the “vengeful God” of the Old Testament and the “loving God” of the New Testament.  It is in the person of Christ that the full manifestation of the Word of God, God’s character and nature, are on full display for us to know and see.  And, at Jesus’ second coming, Irenaeus argues, we shall come to full maturity.  This is participatory language.  Through Christ’s participating in humanity, humanity participates in the very life of God – Father, Spirit, and Son.
