Called “the Harp of the Holy Spirit,” St. Ephrem is the great classic Doctor of the Syrian church. As deacon at Edessa, he vigorously combated the heresies of his time, and to do so more effectively wrote poems and hymns about the mysteries of Christ, the blessed Virgin and the saints. He had a great devotion to our Lady. He was a commentator on Scripture and a preacher as well as a poet, and has left a considerable number of works, which were translated into other Eastern languages as well as into Greek and Latin. He died in 373. Benedict XV proclaimed him a Doctor of the Church in 1920.
