Miaphysitism

451 AD — Chalcedon split

Miaphysitism (from Greek mia = one, physis = nature) is the Christological position of the Oriental Orthodox churches — Coptic, Ethiopian, Syriac, and Armenian. It holds that Christ has one united nature that is both divine and human — not two natures as Chalcedon defined. The key figure is Cyril of Alexandria, whose formula ‘one nature of the Word incarnate’ (mia physis tou theou logou sesarkomene) is the touchstone. Miaphysitism differs from Eutychianism (which was genuinely condemned at Chalcedon as confusing the natures so the humanity is absorbed into the divinity). The Oriental Orthodox insist their position is orthodox Cyrillian theology, not Eutychianism — the dialogue between Oriental Orthodox and Eastern Orthodox theologians in the 20th century has largely concluded that the division is primarily terminological rather than substantive. Both traditions confess the same faith in different philosophical vocabularies.
