Hormisdas
450 — 523 · Feast day: August 6
Pope Hormisdas served as Bishop of Rome from 514 to 523 and ended the Acacian Schism — a 35-year rupture between Rome and Constantinople that began in 484. Through persistent diplomacy and the doctrinal 'Formula of Hormisdas,' he secured the Eastern Church's formal acceptance of the Council of Chalcedon and the primacy of the See of Rome. His son Silverius later became pope.
