One of the major difficulties in thinking through the Incarnation of Jesus Christ is the problem of single or dual subjectivity. The first holds that the subject of every action in the Incarnation is the divine Word of God. Thus we say that God is born, God eats, and God dies and rises. If we were to ask Jesus who He is, in His response of “I AM…” the “I” is the “I” of the Logos, the second person of the Trinity.
This causes some problems and seems to lead us toward a deficient humanity in Christ. The human “I” that each of us is, seems to be lacking in Christ. There is an “I” but it is a divine, not a human self. We find ourselves slipping into a kind of Apollinarian viewpoint in which the self-determining rational mind of Christ is replaced by the Logos.
To check this, we do all we can to buttress the humanity of Christ, insisting on a human spirit and mind, but then finding ourselves in a position in which we are now very close to seeing this collection of elements that make up a human person, doing exactly that. Jesus’ humanity, it seems, must be self-determining to be really human. The “I” of the human Jesus appears to need to be the “I” of a human person otherwise we lose the full humanity of Christ.
But of course, if we follow this well trodden road, we now have two subjective elements, the divine “I” and the human “I”. This falls into the serious problem of the nature of the union between God and our nature. How is it accomplished? If the “I” of Jesus is not divine, how does his life, death, and resurrection help us?
Doctrinally, of course, the Church holds to the Neo-Chalcedonian enhypostatic formula of the human nature of Christ being personal (a person, a subjective ‘I’) in the Logos. A single subject. Yet, if we are sympathetic, we can hear the validity of the concerns of the “two-sons” theology of Antioch.
Perhaps of course, the answer to our conundrum does not lie in trying to refine our formulas to try to explain which elements are maintained and which are lost in the union. Perhaps the answer lies in the deeper mystery of divine Subjectivity.
The “I” of human nature appears to be fundamentally exclusive. It is the “I” that says that I am I and you are you. I am I by not being the “I” that you are. This is, of course, a source of terrible suffering, for selfishness, domination, and abuse all come from the over emphasis of this distinction. But it also is the opportunity for all charity, altruism, and empathy. I cannot have charity if there are no others to love.
This firm distinction of self, however, may not be what is at the base of all creation. The Triune God who is the Father’s self-giving to the Son and Spirit, dwells as the root and base of all self. In the Trinity all self is wholly given away, nothing held back, and no boundaries set up. Distinction, not separation, is the law of love in the Trinity. While we must affirm the “non est” of the Father/Son distinction, we must also more firmly hold to the Dominical mystery that “I and the Father are One.”
One God, not three Gods who share a divine nature. One mystery of three interpenetrating selves giving themselves away wholly and with abandon, patterned on the Father’s foundational gift of self to the Son.
The Self then in the divine life is wholly integrated into the other, or the one who is distinct. We can see the pattern played out Christologically in the Dominical commandments to love our enemies, to give all we have to those who ask, and to love all as brothers and sisters. The divine broadness of selfhood is also revealed in the mystery of the last judgment in which all good and evil done to the least are done to Christ.
It is through these lenses then that we must consider the hypostatic union of single subjectivity that preserves and maintains the fully humanity of Jesus of Nazareth. Only by thinking the whole self-giving and self-identification of the Trinity, and thinking the whole self-giving and self-identification of the Christian life, can we begin to contextualize the mystery of a single subject in Christ.
The subjective “I” of the Logos does not unite itself to any reality to expel that reality from itself. Grace comes to complete, not to destroy. Far be it then that the Logos, in its most perfect union with human nature, should cast out any element, even the human way of saying “I.” Indeed, the Logos unites itself so closely to our nature that our nature can say “I” in the person of the Logos in the way that it says “I” in every other human being. It’s psychology, though unfallen, functions as a human psychology, not driven out by the Logos, but in perfect union with it.
It is a mystery. The perichoretic selves of the Trinity, and indeed the perichoretic selves of Christians, tear down the diabolical demand that I and Thou must always mean different things, while resisting the misunderstanding that they must wholly collapse into each other. Distinction without division is the rule.
These, then, appear to me to be the tools with which we must work at our understanding of the Hypostatic Union of Christ. Let the doctrines of Trinity and Christian love shine a light on the doctrine of the incarnation so that it might shine greater light in return on them.
