He wrote a quite a few of anti-Jewish hymns ( e.g. Hymns of the Unleavened Bread, Carmina Nisibena) which were incorporated into the Syriac and Orthodox church. Recognized as a " Doctor of the Church", he called on his fellow Christians to;" Avoid the Jew… Your death and blood is nothing much to him!... he tramps around the ocean and the land to find companions for the road to Hell." The Prayer of Saint Ephrem, is still recited at every service during Lent and other fasting periods in Eastern Christianity. He is also honored with a feast day by the Episcopal Church (USA) on June 10.There was also a pseudo-Ephram fifty years later who continued fulminations against the Jews including ; " He who eats with a Jew, shall not inherit life in the afterworld."
