Easter event makes clear that JC is always the son, but made perfect in sonship through suffering. Because Logos basis of creaturely independence as generative principal of otherness, nature of Logos can find expression to some extent in all creatures. By this, I think he means that as JC became distinct from the Father, so there's some element of his incarnation in all of us. Human JC shares in deity of Logos but only through mediation of self-distinction from God. Brings creation into the Trinitarian fellowship.
Trinity is both the origin and the result of the event.
