Marcion of Sinope

Marcion of Sinope (/ˈmɑːrʃən, -ʃiən, -siən/; Greek: Μαρκίων Σινώπης; c. 85 – c. 160) was an important leader in early Christianity. His theology rejected the deity described in the Hebrew Scriptures and in distinction affirmed the Father of Christ as the true God. The Church Fathers denounced Marcion, and he chose to separate himself from the proto-orthodox church. He published the earliest extant fixed collection of New Testament books, making him an important figure in the development of the New Testament canon.

Epiphanius records in his Panarion that Marcion was born the son of a bishop in Pontus. His near-contemporaries Rhodo and Tertullian described him as a "mariner" and a "ship-master," respectively. Marcion made a donation of 200,000 sesterces to the church in Rome. Conflicts with the church of Rome arose and he was eventually excommunicated, his donation being returned to him. After his excommunication, he returned to Asia Minor, where he continued to lead his many church congregations and teach the Christian gospel in its Marcionite version.
