Ss. Cyril & Methodius (February 14)
Saints Cyril and Methodius were brothers born in Thessalonica, Greece. Cyril, who was baptized Constantine, assumed the name Cyril when he became a monk shortly before his death. He studied in Constantinople under Photius. He was ordained soon after and became known as "the Philosopher." With his brother Methodius he went to Moravia to preach the faith. They translated liturgical texts into the Slavonic language and invented the Glagolithic and possibly also the Cyrillic alphabet. They were called back to Rome where Cyril died on 14 February 869.
Methodius served as governor of one of the Slav colonies in the Opsikion province. Afterwards he became a monk. In 861, at the request of Emperor Michael II, Cyril and Methodius went on a mission to convert the Khazars in Russia. The two embarked on missionary work that profoundly influenced the Slavic peoples of Eastern Europe. In 862, Prince Rotislav of Moravia asked the Eastern Emperor for Christian missionaries to teach the Gospel to his people in their own language. Photius, now patriarch of Constantinople, assigned the task to Cyril and Methodius in 863. After his brother's death he went to Pannonia, where he was assiduous in the work of evangelization. In the complicated international politics of the time he suffered much from attacks by his enemies, but he was always supported by the Popes. He died on 6 April 885.
