Post-theism is a variant of nontheism that proposes to have not so much rejected theism as rendered it obsolete, that God belongs to a stage of human development now past. As such, it is the opposite of antitheism within nontheism. The term appears in Christian liberal theology and Postchristianity. Denys Turner argues that Karl Marx did not choose atheism over theism, but rejected the binary "Feuerbachian" choice altogether, a position which by being post-theistic is at the same time necessarily post-atheistic.
