Marcions
Marcionism was a Christian sect founded by Marcion of Sinope in the early 2nd century AD. Marcion was a former Christian who had been influenced by Gnosticism and was critical of the traditional Christian understanding of Jesus. He believed that Jesus was a created being, not divine, and that the New Testament was a separate revelation from the Old Testament. Marcion's teachings were highly controversial and led to his excommunication from the Christian community. His followers, known as Marcionites, were eventually absorbed into the broader Christian church. Marcionism is significant in the history of Christianity as it represents one of the earliest attempts to reform the Christian faith, although its influence was ultimately limited.
