The implication of John’s and Paul’s focus on Christ incarnate is that we not only identify who God is through the incarnation, but we begin here because this is who God is. As John Behr notes, the early Church did not presume to start with the pre-incarnate Word – in fact he claims, the term “pre-incarnate” is absent from patristic literature. The order of identification in Gregory of Nyssa, for example, begins with the cross and from the cross (in reference to Ephesians 3:18) the height, depth, breadth, and length, of all things unfolds and returns. As Gregory describes it, the cross is divided into four parts because the One upon it binds together in Himself all forms of existence. The apprehension of all things and the reality of all things converge on the cross.
It is not that the Word became incarnate and then suffered on the cross, but rather the One on the cross is the identity of the Word. The mystery of God revealed as Trinity does not unfold from a fleshless (asarkos) heavenly realm. According to Behr, there has been a serious departure as the subject of Christian theology has changed, from Jesus Christ, the crucified and risen Lord proclaimed by the Gospel, to the narrative of the Word of God somehow devoid of the content of the Gospel. This false narrative pictures an unfolding consecutive order occurring in God. The pre-incarnate Word descends to put on flesh, something like a space-suit, and it is this disembodied Word that is the secret behind the life of the Messiah.
The simple failure here is to recognize that the Word in the Prologue of John is already, by the time of the writing of the Gospel of John, synonymous with the Gospel. The Word, like the Gospel, is about the life, death, and resurrection of Jesus. The “word of the cross” (I Cor. 1:18) upon which apostolic preaching is centered is precisely the details leading up to the passion, the death, and the resurrection of Jesus. The Word is not, for Christians at least, determined by Greek philosophy, the Wisdom of the Old Testament, or even the tetragrammaton (the four-letter name for God which is unpronounceable) which appears under the Aramaic equivalent of Word in the Targums. As Cyril of Alexandria makes clear, Word refers to Jesus Christ: “We say that there is one and the same Jesus Christ, from the God and Father, on the one hand, as the God Word, and, on the other hand, from the seed of the divinely-inspired David according to the flesh.” There is no division in the subject of Christ before and after the incarnation, rather: “One is the Son, one Lord, Jesus Christ, both before the incarnation and after the incarnation.”
Both Cyril and Hippolytus describe a putting on of flesh, but this is not pictured as having been inaugurated from the conception or birth of Jesus but is generated backward in time, having been woven from the sufferings of the cross. Hippolytus, commenting on Revelation 12, pushes the metaphor to suggest this weaving of flesh is an unceasing function of the Church, “bearing from her heart the Word that is persecuted by the unbelieving in the World.” The male child she bears is Christ, God and human, as announced by the prophets, “whom the Church continually bears as she teaches all nations.”
The significance of this focus on the incarnate Christ is spelled out by Irenaeus of Lyons in his insistence that each of the major metaphors for God’s entry into the world – Word, Life, Light, etc. – should not be separated out, or reified as a self-constituting entity, but must be taken as referring to Jesus Christ. The Word, the Light, the Life, is the one who became flesh. Jesus Christ is the Word in the beginning.
What John and the New Testament are conveying is that God has no story but that of Jesus of Nazareth. Jesus Christ is the only Son of God. It is not that the pre-existent Christ and God have a life story, a secret divine story, other than the story of the incarnation or that the Son of God had spent a very long time in eternity – before the incarnation – doing God knows what. Eternity is not a very long time during which God was otherwise preoccupied. Eternity is not time at all and time (an unfolding story) and eternity only intersect in the Son. So, to speak of the Son of God as coming down from heaven is a metaphor that cannot be literally true. The Creator is not subject to spatial (up and down) or temporal (before and after) movement as these are created realms that do not refer to the divine reality.
There are multiple implications to recognizing that the cross and the incarnation are eternal facts about God. Time and eternity, the human and divine, intersect in Christ. History’s center is open to the immanent Trinity and all of history is an unfolding of this intersection in the incarnation and the Church. Jesus Christ is not one episode among many in the story of the Word but is the singular story of God. To imagine God as primarily apophatic, impassive, or apathetic, may be a way of speaking of some God we do not and cannot know, but it is by definition not the God we know through the Word.
This in turn, lends a profound significance to our interaction with the Word through our participation in this story, our continuation of the incarnation as the body of Christ. The specific connections and connectedness we develop in the body of Christ are a participation in who God is, giving our communion, our relationship, our interconnectedness an enduring eternal significance.
