Saint Cyril was born in Thessalonica and educated in Constantinople. He accompanied his brother Methodius to Moravia to preach the faith. They both prepared Slavic liturgical texts in what would subsequently be known as the Cyrillic alphabet. Both were summoned to Rome, where Cyril died on February 14, 869, while Methodius was consecrated Bishop and went to Pannonia where he tirelessly preached the Gospel. Though suffering much from detractors, he received assistance from the Roman Pontiffs. Methodius died on April 6, 885 in Velehrad, Czechoslovakia.
Father, you brought the light of the gospel to the Slavic nations through Saint Cyril and his brother Saint Methodius. Open our hearts to understand your teaching and help us to become one in faith and praise. Amen.
