St. Luke addressed his Gospel and the Acts of the Apostles to a man named Theophilos. Who was Theophilos? Scripture scholars do not know, making him a fit subject for Michael O'Brien's vivid imagination. In this fictional narrative, Theophilos is the skeptical but beloved adoptive father of St. Luke. Challenged by the startling account of the "Christos" received in the chronicle from his beloved son Luke and concerned for the newly zealous young man's fate, Theophilos, a Greek physician and an agnostic, embarks on a search for Luke to bring him home. He is gravely concerned about the deadly illusions Luke has succumbed to regarding the incredible stories surrounding Jesus of Nazareth, a man of contradictions who has caused so much controversy throughout the Roman Empire.
