Three Chapters controversy
The Three Chapters controversy showed how hard it was to repair the damage after Chalcedon. Justinian condemned writings linked to Theodore of Mopsuestia, Theodoret, and Ibas, hoping anti-Chalcedonian Christians would see that the empire rejected Nestorian tendencies. Many Western bishops saw the move as imperial pressure and a betrayal of Chalcedon. The result was not reconciliation, but new fractures in North Africa, Italy, and Aquileia.
Trying to heal Chalcedon created another wound.
Highlights
- Justinian targeted Antiochene writings.
- Western bishops resisted.
- Pope Vigilius was pressured.
- Aquileia broke communion.
How it happened
What happened
Justinian pushed for the condemnation of three bodies of Antiochene writings.
The argument
Was condemning long-dead Antiochene theologians a faithful defense of Cyril or an attack on Chalcedon?
What changed
Constantinople II condemned the Three Chapters, but Western resistance hardened.
Why it matters
The controversy shows that posthumous condemnations could destabilize communion as much as clarify doctrine.
