Saints Cyril and Methodius were brothers. They were born in Greece and educated in Constantinople. They were the great apostles of the Faith to the Slavs in southern Russia, in Bohemia and Poland during the ninth century. Though Saint Cyril and Saint Methodius died sixteen years apart, their feasts are celebrated together. They are responsible for the Slav alphabet, and indeed, for the Slav language. Pope John Paul II made Saint Cyril and Saint Methodius patrons of Europe, along with Saint Benedict.
