Marcionites

Marcionites- Said that the creator "god" of the Old Testament was not the good God and Father of Jesus Christ of the New Testament. Had their own shadow hierarchy and their own Bible, which consisted of parts of Luke and Paul, edited so as to disparage the Old Testament. Only the unmarried were allowed to be baptized. Marcionism may have led to the formation of the Apostle's Creed as rebuttal, and certainly was an incentive in deciding on the canon of the New Testament.
