Someone recently asked on Facebook for what the best works on theosis were. It raised many resources I knew and a couple I wasn’t aware of. I’m not really staying up on the forefront of things now that I’m writing about justification in Paul. As to the question, I gave my to go-to volumes which are good primers: Daniel Keating’s Deification and Grace (mostly focused on patristic views), and Norman Russell’s Fellow Workers with God (patristic views in light of wider contemporary Orthodox perspectives). Of course, Russell’s The Doctrine of Deification in the Greek Patristic Tradition is the gold standard for patristics, and I’m partial to this Christosis volume which brings together Paul and theosis.

In the thread this was posted:

Question by an ignorant person for all: I get God’s communicable attributes, sanctification, and in this way taking on the divine nature, being conformed to Christ, etc. I get believers’ mystical union to Christ, Christ living in us, etc. Does Theosis go beyond this, and if so, how so? And how is that not a bad thing? And if it does not go beyond this, then why are people lusting over the peculiar terminology?

Is theosis a fad? If not, what’s it got going for it? These are good questions. Here’s the answer I gave:

I’m sure there is a fad element to this, but there is a coherence it provides that some of our current theological dichotomies miss. In the patristic tradition, the terminology of theosis served a catch-word for the whole salvation-historical work of God–uniting creation and new creation. As such, it is not primarily anthropological (merely regarding salvation) but theo-logical and salvation-historical. In that way, it served to speak to the whole story of the Bible. (In case you are interested, I spell this out further in a recent essay: “You Become What You Worship: Theosis and the Story of Bible,” Ex Auditu (2017): 1–20.) For patristic theologians, it also incorporated their cosmological framework, in that participation was what explained the way of all reality. God is the only true self-existent being, and all life inheres to him, so to the extent we have life, we are participating in God’s life, which is again a reaffirmation of a theo-logical perspective. Finally, it provides a coherence in the narration of anthropological salvation: it is not just “sanctification” but participating in the life of God, so it unites life now and life in the future, moral incorruption (sanctification) and somatic incorruption (resurrection). So, one term that captures all that is handy.

If you are looking for a little on this topic, here’s something as a primer on theosis and theosis for dummies.


From the earliest days of the Christian faith, Christians have struggled with the question of how the newness of Christ relates to the Old Testament. In fact, it is almost accepted as a truism today among most Christians that the God of the Old Testament is mad, angry, and vengeful, but the God of the New Testament is forgiving and gracious. And yet, Christianity is the fulfillment of OT promises and expectations. Should we leave behind the Old Testament? Should we only be “New Testament Christians”? In our 2019 Houston Theological Seminary Theology Conference, we address these very questions and explore the relevance of the Old Testament for Christian faith and practice. Our keynote speaker, Dr. Daniel Block, will address this under the rubric “All Scripture is My Scripture: Rehitching the First Testament to Christian Faith.” In addition, we will have a variety of other speakers from HBU and Second Baptist Church, representing academic and pastoral perspectives.

All are welcome! Come join us, and share this link with your friends:

Continuing my series on Theophilus of Antioch and his work To Autolycus (Ad Autolycum), I am addressing theosis or deification in his work. (Previous posts address Christianity in antiquitythe parting of the waysTrinity without Christology, and Theosis in Theophilus.) If you are lost by my terminology of theosis, see my primer on theosis and theosis for dummies.

As part of his apologetic for Christianity, Theophilus establishes Christianity as deriving from the most ancient part of antiquity–creation itself. In this discussion of creation, he described the telos of humanity arising from their original creation, that they should become immortal like God. Indeed, they would be called “gods” because they share in this immortal attribute, though they clearly remain distinct in nature and identity from God. This shares the basic framework that almost all later writers about theosis or deification share.

Placing this discussion of becoming gods in terms of creation fits his rhetorical purpose, but it also frames the nature of continuity in almost all discussions of theosis, that is, the creator of the world is also its savior. Thus, others often place their discussion of deification in terms of creation. Theophilus is unique among other patristic writers because he does not use Psalm 82:6 to ground his reading. However, the outcome is exactly the same since when Irenaeus and others discuss Psalm 82:6, they always narrate it according to mortality at the fall and the hope of immortality. However, Irenaeus also places this within his larger salvation-historical narrative in which Christ is the one through the Spirit who restores immortality to humanity. I explore the importance of theosis for helping capture the “story of the Bible” in an essay that came out earlier this year.

Thus, what is unique about Theophilus is not that he speaks of human identity and salvation in terms of becoming gods, nor that he places this deification discussion in terms of creation and new creation. No, what is unique is that he describes resurrection and immortality in terms of God alone and not through Christ’s death and resurrection. In my work on Paul and theosis, I titled the book Christosis because I argued that Paul’s discussion of soteriology could be described as theosis, but it was explicitly framed in terms of embodying the death and life of Christ.

Note: By Christosis, I expressly do not mean: 1) this is a Christological-only soteriology because being transformed into the image of Christ is almost always in the context of the Spirit’s work (and being a “christ” entails being anointed by the Spirit). 2) Christosis should be distinct from theosis, especially not in parallel to the Christotokos-Theotokos distinction. Christosis is intended to point to a Pauline emphasis within the wider framework of theosis.

In distinction to Paul, Irenaeus, and the many other patristic writers who wrestle so distinctly with the Christ-event and its relation to theology, Theophilus has a “Christianity without Christ” as I have explored in an earlier post. He has a Logos-theology and indeed an distinctly Trinitarian discussion of God, but at least here when he describes the telos of humanity in terms of divine immortality, he does it in a generically God way, thus my phrase theosis without christosis.


Continuing my series on Theophilus of Antioch and his work To Autolycus (Ad Autolycum), I am addressing theosis or deification in his work. (Previous posts address Christianity in antiquitythe parting of the ways, and Trinity without Christology.) If you are lost by my terminology of theosis, see my primer on theosis and theosis for dummies.

In his defense of Christianity, Theophilus begins his work by establishing the identity of God (1.1-7). He is immortal, invisible, uncreated, and immutable. He is the maker of the universe, which was created ex nihilo. Even though we cannot see him because he is beyond the created order, we can know him through creation if we have a pure heart for these pure at heart can know God. Thus he concludes: “If you know these things, O man, and live in purity, holiness, and righteousness, you can see God” (1.7).  He later continues: “When you put off what is mortal and put on impershability, then you will rightly see God. For God raises up your flesh immortal with your soul; after becoming immortal you will then see the Immortal, if you believe in him now” (1.7). This draws from the ancient conception that you had to become like something to know it (“like is the friend of like” as described in Plato’s works). As we become like God in holiness and moral incorruption, then we can know God. Importantly, Theophilus then turns immediately to somatic incorruption as the hope for those who believe and know God (1.8). The basic idea is that even though humanity is fundamentally distinct from God because of creation ex nihilo, humanity can truly be in relationship with God and share in God’s attributes, namely incorruptability.

Note: We see this exact interchange between knowing God and overcoming death through immortality in Athanasius’ On the Incarnation. Note there how the first 10 chapters or so are about experiencing immortality and overcoming mortality through Christ’s incarnation, death and resurrection. Then, the next 10 chapter or so are about knowing God, but without a hint of any transition. Athanasius like many ancients saw a fundamental coherence between knowing God and being like him.

Theophilus’ discussion of resurrection early in the treatise points to the importance of immortality within his basic anthropology and soteriology. We see this played out in much more detail in his discussion of creation, and this is where his discussion of deification comes into play. One of his fundamental arguments about anthropology is that humanity was not created naturally immortal, but God had the intention that humanity would be immortal (2.19, 24, 27). We might call this conditional immortality, and Irenaeus also reflects a similar perspective (AH 38-39).

It is in these contexts that Theophilus uses deification language, describing humans as “gods” (2.24, 27). For example:

For if God had made him immortal from the beginning, he would have made him God. … God therefore made him neither immortal nor mortal but, as we have said before [2.24], capable of both. If he were to turn to the life of immortality by keeping the commandment of God, he would win immortality as a reward from him and would become a god…” (2.27).

While humans chose disobedience, Theophilus makes clear that humans can attain resurrection and imperishability, which in the flow of the argument would make them implicitly gods.

Of course, this is a metaphorical ascription. Given the Creator-creature distinction that undergirds this discussion (from Book 1), I would describe this as example of “attributive deification” using the taxonomy that I developed in my book ChristosisHumans share through participation in the attributes of divinity, and so they become like God while remaining distinct in their essence or nature. Though it is a metaphor to be called “gods,” it entails an ontological transformation, not in terms of the change their nature to a new nature (or species), but their mode of being changes. Here the primary emphasis is on participation in divine immortality, but as we saw above their is a distinct interconnection between these different forms of incorruption–noetic, moral, and somatic.

Theophilus gives us an early witness on deification and theosis and he grounds this doctrine of theosis in the Bible. This basis framework is not too unique, given that Irenaeus, follows a similar pattern. However, part of the contextualization is different, and so I’ll continue with a separate post on that.

I’m doing a short my series on Theophilus of Antioch and his work To Autolycus (Ad Autolycum). Previous posts address Christianity in antiquity and the parting of the ways. I’m now addressing his Christology and Trinitarianism.

In describing Theophilus’ treatment of Christ, Grant writes: “His understanding of the work of Jesus Christ can be recovered only from allusions, for like other apologists of his time he never openly speaks of him” (xvii).

For example, Theophius does not mention Christ’s crucifixion but does note the hope of resurrection (1.8, 13). He exclaims that he is a “Christian” right at the very beginning (1.1). When exploring the derivation of the name “Christian” (1.12), he does not mention Jesus as the Christ, but rather speaks of Christians as being anointed with the oil of God. When describing faith (1.14), he notes the hope of resurrection and eternal punishments, but not Christ. Mentions existence of the Gospels (3.12), and when quoting Jesus’ teaching in Matthew 5.28, he describes “the gospel” speaking rather than naming Jesus (3.13, 14). When addressing the charge of cannibalism (3.15), which surely arises from the Lord’s supper, he does not explain the practice or its relation to Jesus, he only rejects it and points to cannibalism in the Greco-Roman theogonies (3.5, 15).

If he never mentions Jesus or the Christ, does he speak of the Christian plurality? Yes, he commonly refers to God in relation to the Logos and Sophia (Wisdom). Sophia is most commonly associated with the Holy Spirit (e.g., 1.7, 13, etc.). The three are most clearly delineated in terms of creation. After an extensive critique of the Greco-Roman myths and theogonies, he turns to explore creation and this takes up the majority of Book 2. To ground his creation theology before walking through Genesis, Theophilus speaks of God creating ex nihilo with the Logos and Sophia (2.10). The chapter is longer than most and has a well developed interaction between the three before walking through Genesis (2.11ff.). Importantly, he uses several passages from the Bible to explain his proto-Trinitarian position.

Later, we also see the three when he explains Gen 1.26 with its affirmation: “Let us….” He argues that human dignity was shown through that “the making of man [was] the only work worthy of his own hands” (2.18). Theophilus then describes why the text has “us” there, by appealing to God’s speaking to “his own Logos and his own Sophia” (2.18).  Though he does not directly call the Logos and Sophia God’s hands, the implication is clear. This is the same language that Irenaeus commonly uses.

In the midst of this wider discussion Genesis, is when explaining day 4 with the sun and moon, Theophilus uses some of the first distinctly trinitarian language. After describing the sun and moon as types of God and man, and the greater and lesser, he explores other types:

Similarly the three days prior to the luminaries are types of the triad/trinity (τύποι τῆς τριάδος) of God and his Logos and his Sophia. In the fourth place is man, who is in need of light–so that their might be God, Logos, Sophia, man. For this reason the luminaries came into existence on the fourth day. (2.15).

There is much more to explore here, but it is very interesting that Theophilus is one of the earliest uses of “trinitarian” language, and yet he does it without an emphasis on “Christ” but rather the Logos. J. Bentivegna has an essay on Theophilus describing it as “A Christianity without Christ.” Thus, we might say also Trinity without Christology. Of course, this work does not capture everything that Theophilus had to say. (A similar dilemma shows up with Boethius, whose Consolation of Philosophy which is distinctly monotheistic such that you might wonder if he is a Trinitarian also has a work On the Trinity.) However, it is hard to square how you can have such a seemingly developed idea in one side of a topic but without the coordinate discussion of other issues.
