Saint Ephrem the Syrian has a special message to offer to theology today. The model he gives in opening the spiritual eyes for the light of Christ to radiate in his body, leads to radiating this light into pastoral action. Thus, pastoral theology ought to be based on this experience of light, practiced in spiritual words and actions. Saint Ephrem wrote teaching hymns, defending the faith against heresies, and fighting social injustice. As an enlightened man of God, he became a master of both spirituality and pastoral ministry. This research aims to analyze how Saint Ephrem translates his personal experience of light into pastoral work, by examining how he expresses his theological thought, interprets pastoral theology, and presents the ministry of episcopacy in particular. For this Antiochian saint, theology is a hymn to the Light, translated into genuine acts of love, faith, and life.
