Marcion was a heretic who believed in dualism. He taught that the God of the Old Testament was an inferior, weaker God who focused too much on the law and that the God taught by Jesus was a superior God who focused on the right things: love, compassion, and mercy.
Marcion developed his own canon to replace what he believed was a faulty canon that included the Old Testament. He believed that Paul was the only apostle who truly understood what Jesus taught.
