Cyril of Alexandria

Hierarch

Commemorated January 18 · June 9

Our father among the saints Cyril of Alexandria was the Pope of Alexandria at the time Alexandria was at its height in influence and power within the Roman Empire. Cyril wrote extensively and was a leading protagonist in the Christological controversies of the 4th and 5th centuries. He was a central figure in the Council of Ephesus in 431 which led to the deposition of Nestorius as Archbishop of Constantinople. Cyril is among the patristic fathers, and his reputation within the Orthodox Christian world has led to his acquiring the title "Seal of all the Fathers." His feast day is celebrated on June 9 and, with St. Athanasius of Alexandria , on January 18 .
