Read the full account

In May 553 an imperial council at Constantinople, later counted as the Fifth Ecumenical Council, condemned the Three Chapters. Pope Vigilius, brought to the city, resisted then yielded. Justinian’s court ran the agenda. This is not the 543 edict that opened the quarrel.

Context

African and Illyrian bishops had been the western holdouts. Some were deposed. Polarization here is church-political, with long schism in parts of Italy. Sharing the acts with assembled bishops is required; the emperor’s will is still the reason the council met.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

Why it matters

Worsening polarization path. High confidence on the council’s condemnation.

Confidence is stated on the impact path, not hidden in adjectives. Mixed effects of The Second Council of Constantinople condemns the Three Chapters are separate paths.

What the sources establish

English reprints of the 553 acts exist as public carriers. Britannica independently dates the Second Council of Constantinople. Western Latin sources independently record Vigilius’s pressure. The URLs differ.

Established: the 553 council under Justinian’s direction condemned the Three Chapters. Not established: that western churches freely agreed, or that miaphysites reunited.

Shared responsibility is part of The Second Council of Constantinople condemns the Three Chapters. Naming Justinian I does not delete co-authors, institutions, or later transmitters. The lag from 0553-05-05 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

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

If a number is not in the two records named above, it is not supplied here.
