Cyril Patriarch of Alexandria
In A.D. 422 Celestine (I) was elected pope, a position he kept until April 6, 432. He opposed the Nestorians, Pelagians, and puritanical Novatians, who opposed forgiving apostates. On the urging of Patriarch Cyril of Alexandria, Celestine convoked the Council of Ephesus [see Ecumenical Councils] to fight the position of Nestorius, bishop of Constantinople. Nestorius supported the idea that Mary was the Christbearer (Christotokos), rather than the Godbearer (Theotokos). Christ means 'anointed', as in the savior of mankind, but it doesn't signify divinity.
Celestine may have sent St. Patrick as a missionary to Ireland.
