Also known as Ephrem the Deacon (c. 306 - 379)
A Doctor of the Church, Ephrem is one of my favorite saints. I studied his hymns and some of his homilies in graduate school. He wrote over 400 hymns, and I think they're just awesome.
Here's an excerpt from his Second Hymn on The Nativity:
Blessed be that Child, Who gladdened Bethlehem to-day! Blessed be the Babe Who made manhood young again to-day! Blessed be the Fruit, Who lowered Himself to our famished state! Blessed be the Good One, Who suddenly enriched our necessitousness and supplied our needs! Blessed He Whose tender mercies made Him condescend to visit our infirmities!
Praise to the Fountain that was sent for our propitiation. Praise be to Him Who made void the Sabbath by fulfilling it! Praise too to Him Who rebuked the leprosy and it remained not, Whom the fever saw and fled! Praise to the Merciful, Who bore our toil! Glory to Thy coming, which quickened the sons of men!
Glory to Him, Who came to us by His first-born! Glory to the Silence, that spake by His Voice. Glory to the One on high, Who was seen by His Day-spring! Glory to the Spiritual, Who was pleased to have a Body, that in it His virtue might be felt, and He might by that Body show mercy on His household's bodies!
