The Antitheses
Marcion of Sinope · c. 85–c. 160
What it is
A systematic set of contradictions between the Old Testament and the gospel, arguing that the creator God of Israel is a lesser being than the alien God of love revealed by Jesus. Known only from the refutations of Tertullian and others.
Why it lasted
Marcion's canon of one gospel and ten letters forced the wider church to say which books were actually scripture — the single greatest provocation behind the New Testament canon.
