04 — The Events of 1054

The famous exchange of anathemas — Cardinal Humbert’s bull on the altar of Hagia Sophia (16 July 1054) and the synodal counter-anathema (24 July) — was personal in scope, doubtful in canonical force, and barely noticed by contemporaries; the wisest voice of the hour, Peter III of Antioch, refused to treat the Latins as severed brethren. This section narrates what actually happened and how a limited quarrel was mythologized into “the day the Church split.”

Tradition: Pan-Orthodox
