If Jesus Christ is a union of human and divine natures, was his human nature co-eternal with God, or only his divine nature? John 1:14 (“and the Word was made flesh”) seems to imply that the Incarnation took place later. That, in turn, suggests that Jesus Christ’s human nature “happened” later—it was not present at the beginning, not co-eternal with God (except, perhaps, as a potentiality). If so, then can it be said that the joint human-divine nature of Jesus Christ is the second person of the Holy Trinity? Or is only the divine nature of Jesus Christ (the Logos) the Second Person? How could Jesus Christ’s human nature be part of the Trinity if it is not co-eternal with God?
