St. Paul, the Apostle, original name Saul of Tarsus, was one of the leaders of the first generation of Christians, often considered to be the most important person after Jesus in the history of Christianity. In his own day, although he was a major figure within the very small Christian movement, he also had many enemies and detractors, and his contemporaries probably did not accord him as much respect as they gave Peter and James. Paul was compelled to struggle, therefore, to establish his own worth and authority.
