Alexandrian miaphysite Christology
The Coptic tradition upholds the full unity of the incarnate Word in Cyrillian and Alexandrian language.
What it is: This belief confesses that Christ is one incarnate Word, fully divine and fully human in an undivided unity.
How the tradition understands it: The Coptic tradition insists that miaphysite language preserves Christ's full humanity and full divinity without dividing the subject of the Word. For this reason, it rejects being reduced to a crude monophysitism.
Textual or traditional basis: John 1, Philippians 2, Cyril of Alexandria, and the reception of Ephesus are central sources.
Historical context: The position was consolidated in the Christological controversies of the fifth and sixth centuries surrounding Chalcedon.
Common objections: Historical opposition accused the position of confusing the natures; the Coptic tradition replies that this caricatures its faith.
Internal variations: The language may vary in nuance, but the miaphysite orientation is normative.
