Marcion of Sinope
Marcion of Sinope (; Greek: ; 85 – c. 160) was an early Christian theologian, an evangelist, and an important figure in early Christianity. Marcion preached that the benevolent God of the Gospel who sent Jesus Christ into the world as the savior was the true Supreme Being, different from and opposed to the malevolent demiurge or creator god, identified with the Hebrew God of the Old Testament. 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. Marcion published the earliest extant fixed collection of New Testament books, making him a vital figure in the development of Christian history.
