Ephrem the Syrian was a Syriac Christian deacon and a prolific Syriac-language hymnographer and theologian of the fourth century. Ephrem is especially beloved in the Syriac Orthodox Church, and counted as a Venerable Father (i.e., a sainted Monk) in the Eastern Orthodox Church. His feast day is celebrated on 28 January and on the Saturday of the Venerable Fathers. He was declared a Doctor of the Church in the Catholic Church in 1920.
