In this revelatory documentary, David Suchet (Agatha Christie's Poirot) sets off in search of one the great figures of the Bible-St. Paul the apostle. Controversial in his own time, Paul remains so today, a remarkable man of contrasts and confusions, a persecutor of Christians who experienced a miraculous conversion and an all-consuming drive to spread the faith. More than any other single person, Paul transformed Christianity from a small Jewish sect into the most powerful religion on earth. Long fascinated by the apostle, Suchet takes a very personal quest, retracing the steps of a man believed to have traveled some 10,000 miles by foot across the lands of the Roman Empire and many more by sea. Along the way, Suchet talks to archaeologists, scholars, clerics, and locals, each of whom sheds light on an individual who did so much to shape the history of Western civilization.
