In 543/544 Justinian issued an edict condemning the so-called Three Chapters — specified writings and a person among the older Antiochene theologians — hoping to win miaphysites without dropping Chalcedon. Western bishops read it as tampering with the council of 451. This is the opening edict, not the 553 council that later rubber-stamped it.

Context

Theodora’s miaphysite patronage is court context. Facundus of Hermiane and African bishops resisted. Polarization here is ecclesiastical-political. The Gothic War made Italian bishops hostages to imperial theology. Sharing the controversy with Vigilius is the next council row.

The contribution type is direct. That reading is an impact-path choice, not a property stored on the Fact itself.

Why it matters

Worsening polarization path inside the imperial church. Direct contribution. High confidence on the edict.
