Miaphysite Christology
Christ is confessed as the incarnate Word in full unity of divinity and humanity.
What it is: Miaphysite Christology affirms that the incarnate Word is one single Christ, in whom divinity and humanity are united in a real way, without confusion, separation, or division in the subject of the Word.
How the tradition understands it: Eastern Orthodox churches frequently insist that their position is not a denial of Christ's full humanity, but a defense of the unity of the incarnate person in language inherited from Cyril of Alexandria. For this reason, many reject the simplistic label of monophysitism.
Textual basis or tradition: John 1, Philippians 2, the Cyrillian anathemas, and the formula of 'one incarnate nature of the Word of God' are fundamental.
Historical context: The formulation took shape in the post-Ephesus controversies and in the negative reception of Chalcedon by these churches.
Common objections: Historical critics accused the position of absorbing Christ's humanity; defenders respond that this distorts their self-understanding.
Internal variations: Technical language can vary among Coptic, Syriac, Armenian, and Ethiopian traditions, but the general orientation is common.
