John of Damascus, Monk

4 December -- Commemoration
If celebrated as a Lesser Festival, Common of Teachers, page 473

John was born in Damascus in about the year 657. Although the city was already Muslim, his father, though a Christian, was Chief of the Revenue and was the principal representative of Christians in the city. In 716, John, by then well-educated in science and theology, became a monk at the abbey of St Sabas near to Jerusalem and later was ordained priest there. He became a prolific writer of theological works and of hymns. His summary of the teachings of the Greek Fathers, called De Fide Orthodoxa, proved an immense influence in the Church in the following centuries, in both east and west. He died on this day in about the year 749.
