Pandeism (or pan-deism) is a theological doctrine which combines aspects of pantheism into deism. It holds that the creator deity became the universe and ceased to exist as a separate and conscious entity. Pandeism is proposed to explain, as it relates to deism, why God would create a universe and then abandon it, and as to pantheism, the origin and purpose of the universe.
