Condemnation · 451 · 8 October
Eutyches condemned at Chalcedon
Eutyches was condemned for protecting Christ's divinity in a way that endangered his real humanity. He spoke as though Christ's humanity was absorbed after the union, leaving one nature where Chalcedon confessed two. The council rejected that because a humanity swallowed by divinity cannot be the humanity Christ came to heal. Chalcedon therefore guarded both truths at once: fully God, fully human, one Lord.

How it happened
What happened
Chalcedon rejected Eutyches's language about Christ's humanity after the incarnation.
The argument
Does the union with the Word absorb Christ's humanity, or does his humanity remain real and complete?
What changed
The council confessed Christ in two natures after the union.
Why it matters
A Saviour without real humanity cannot heal real human nature.
Aftermath
The anti-Eutychian settlement helped define Chalcedon but also sharpened non-Chalcedonian resistance.
