Second Council of Constantinople

Condemned the “Three Chapters”: the person and writings of Theodore of Mopsuestia, certain writings of Theodoret against Cyril, and the letter of Ibas of Edessa to Mari. Its 14 anathemas interpret Chalcedon in a Cyrilline sense (e.g. “one of the Trinity suffered in the flesh”), in an attempt to reconcile Chalcedon's opponents. Pope Vigilius, who was in Constantinople, refused to attend but later approved the decisions (553–554), which triggered the Three Chapters schism in the West.

Convoked by

Emperor Justinian I
