Marcion

Considered a heretic by orthodox Christianity, Marcion was the son of a Christian bishop and active in the church in Rome in the 2nd century (c. 144 C.E.). He saw the world as evil and despised Judaism. He concluded that the creator of earth was evil, rejected the Hebrew Bible (Old Testament), and believed the God of the Hebrew Bible was arbitrary and vindicative illustrated respectively by the deity’s choice of the Hebrews over all other people and by the deity’s accounting for all disobedience and punishment of all such disobedience.

Marcion believed the God of Jesus intended only a spiritual world and this God is loving, requires nothing of us, and gives salvation freely. Marcion denied the birth narratives of Matthew and Luke and believed that Jesus appeared full-grown during the reign of Tiberius. Because of his rejection of the Hebrew Bible, he delineated his own New Testament that included Paul’s epistles and a version of Luke’s gospel expunged of any references to the Hebrew Bible or Judaism. In opposition to the church in Rome, Marcion established another church in Rome that lasted for a few centuries after his death.
