A Jew from the Greek city of Tarsus in Anatolia, he initially persecuted the followers of Jesus but, after receiving a revelation on the road to Syrian Damascus, became a Christian. Taking advantage of his Hellenized background and Roman citizenship, he traveled throughout Syria-Palestine, Anatolia, and Greece, preaching the new religion and establishing churches. Finding his greatest success among pagans ('gentiles'), he began the process by which Christianity separated from Judaism.
