Paul of Tarsus was one of the most influential theologists of Christianity. His theology was developed after his journey to Damascus where he had an enlightening experience which involved a personal encounter with God. This revelation completely transformed is mindset and ambitions. He was no longer determined to persecute believers of Christ, but rather was motivated to convert others to Christianity and to preach to the world that Jesus is the promised Messiah. Paul’s Christocentric theology taught that all men and sinners are in need of redemption which is provided by Jesus Christ, the Son of God, whom God sent to Earth to save mankind from sin. It proclaims that Jesus is the fulfillment of all the prophecies within the Old Testament of the Bible and that Jesus justifies all who believe in him. Paul developed Christian doctrine. He contributed to aspects of the doctrine such as Salvation, the theology of the atonement of Jesus’ death and eschatology.
