Influential heretic who came to Rome in 140 CE and established schismatic congregations. He held that the God of the OT was a God of Law and wrath, and not to be identified with the NT concept of the God of Love, revealed by Jesus. Paul was, he said, the apostle who understood this, and accordingly ten of his epistles, suitably edited, formed the major part of Marcion's canonical scriptures. Of the gospels, he accepted only an abbreviated version of Luke. Such radicalism may have encouraged Marcion's ‘orthodox’ opponents to consider which Christian writings were authoritative for the life and faith of the Church.
