The saints behind the name
Cyril of Alexandria
January 18, Hierarch, Κύριλλος Αλεξανδρείας
St. Cyril was Archbishop of Alexandria in the fifth century. He presided at the Third Ecumenical Council at Ephesus in 431, which condemned Nestorius and confirmed that the Virgin Mary is truly Theotokos, the Mother of God.

Cyril of Jerusalem
March 18, Hierarch, Κύριλλος
St. Cyril was Archbishop of Jerusalem in the fourth century, a gentle and learned shepherd of the Holy City. His famous Catechetical Lectures, delivered to those preparing for baptism, remain one of the treasures of the ancient Church, setting forth the faith and the holy mysteries with clarity and warmth.

Cyril and Methodios, Enlighteners of the Slavs
May 11, Apostle, Κύριλλος και Μεθόδιος
Cyril (baptized Constantine) and his elder brother Methodios were born in Thessalonica in the ninth century. Sent by the Emperor and Patriarch Photios to Moravia, they devised an alphabet for the Slavonic language and translated the Scriptures and services, so that the Slavs might worship in their own tongue.
