The Council of Chalcedon (451 A.D.) established the dual nature of Jesus Christ while he himself is one person. These natures are fully human and fully divine. The Chalcedon Creed, rewritten for today’s audience, might look like this:
We have all agreed to teach man, following the holy Fathers, that our Lord Jesus Christ is truly God and truly man, composed of soul and body. He is complementary to the Father according to God and complementary with us according to man. He is like us, without sin, brought before us by God. Comparably, he was born of the Virgin Mary to deliver us from sin. These two natures – the divine and the human – are not to be confused, separated, or changed. These natures coexist in one body that is Jesus Christ. The prophets, Jesus himself, and the Creed of the holy Fathers has passed this down to us.
