St. Cyril of Alexandria
Patron of theologians
Saint Cyril of Alexandria (c. 376–444) was born in Egypt of a distinguished Christian family and succeeded his uncle Theophilus as Patriarch of Alexandria in 412. Trained in the desert monasteries and in the rich theological tradition of the Alexandrian school, he proved himself one of the most penetrating dogmatic minds of the Greek Fathers, devoting his life to the defense of the unity of Christ — true God and true man in one divine Person.
