Acacian Schism

484-519. A schism between the Eastern Church and Rome during the Monophysite* controversy, arising from the high-handed excommunication of Acacius of Constantinople* by Felix III of Rome. Attempts by succeeding patriarchs and emperors to heal the breach failed because of Rome's extravagant demands. On the accession of Justin I, however, Patriarch John yielded to Pope Hormisdas, and removed the names of Zeno, Acacius, and his five successors from the “diptychs,” ending the schism.
