Council · 553 · 5 May

Second Council of Constantinople

Constantinople II was an attempt to hold Chalcedon while winning back Christians who thought Chalcedon sounded too Nestorian. Justinian pushed the condemnation of the Three Chapters, writings associated with Antiochene theologians suspected of dividing Christ too sharply. The council also became associated with condemnations of Origenist speculations. Its legacy is complicated: it defended Cyril's Christology, but it also deepened mistrust between emperor, pope, and divided churches.

How it happened

What happened

Justinian pressed the council to condemn the Three Chapters and distance Chalcedon from Nestorian-sounding theology.

The argument

Could the empire reassure anti-Chalcedonian Christians without betraying Chalcedon itself?

What changed

The council condemned writings linked to Theodore of Mopsuestia, Theodoret, and Ibas, and became associated with condemnations of Origenism.

Why it matters

It shows the cost of trying to heal doctrinal division by imperial pressure and retrospective condemnation.

Aftermath

Instead of ending the division, it provoked Western resistance and new schisms, especially around Aquileia.
