Marcion of Sinope (; Greek: ; 85 – c. 160) was an important figure in early Christianity. Marcion preached that the God who sent Jesus into the world was a different, higher deity than the creator god of Judaism. He considered himself a follower of Paul the Apostle, whom he believed to have been the only true apostle of Jesus Christ, a doctrine called Marcionism. He published the earliest extant fixed collection of New Testament books, making him a vital figure in the development of Christian history.
