Marcionism

Marcionism was an early Christian theological movement founded by Marcion in the 2nd century. It held that the God revealed in the Old Testament was a vengeful, inferior deity distinct from the loving God of Jesus Christ in the New Testament. Marcion rejected the Old Testament entirely, emphasizing only parts of the New Testament, particularly Paul's writings, and saw Jesus as a new, divine messenger who brought salvation. His views challenged mainstream Christianity, prompting the church to clarify its doctrines and canon. Overall, Marcionism highlighted debates about God's nature and the relationship between the Old and New Testaments in early Christian thought.
