On June 27, Roman Catholics will honor St. Cyril of Alexandria. An Egyptian bishop and theologian, he is best known for his role in the Council of Ephesus, where the Church confirmed that Christ is both God and man in one person. The Eastern churches celebrate St. Cyril of Alexandria on June 9.
Cyril was most likely born in Alexandria, the metropolis of ancient Egypt, between 370 and 380. From his writings, it appears he received a solid literary and theological education. Along with his uncle, Patriarch Theophilus of Alexandria, he played a role in an early fifth-century dispute between the Egyptian and Greek churches. There is evidence he may have been a monk before becoming a bishop.
When Theophilus died in 412, Cyril was chosen to succeed him at the head of the Egyptian Church. He continued his uncle's policy of insisting on Alexandria's preeminence within the Church over Constantinople, despite the political prominence of the imperial capital. The two Eastern churches eventually re-established communion in approximately 418.
Ten years later, however, a theological dispute caused a new break between Alexandria and Constantinople. Cyril's reputation as a theologian, and later Doctor of the Church, arose from his defense of Catholic orthodoxy during this time.
