Saul of Tarsus, later known as the Apostle Paul, was a significant figure in early Christianity. Born in Tarsus, a city in modern-day Turkey, he was a Pharisee who initially persecuted Christians. His education and Roman citizenship gave him a unique perspective on both Jewish and Gentile cultures. After a dramatic conversion experience on the road to Damascus, Saul became a devoted follower of Jesus Christ. He traveled extensively, spreading the message of Christianity and establishing several churches. His letters, known as the Epistles, form a substantial part of the New Testament and continue to influence Christian theology today.
