Pandeism (Greek πάν, 'pan' = 'all' and Latin deus = God, in the sense of deism), is a term used at various times to describe religious beliefs. Since at least as early as 1859, it has delineated syncretist concepts incorporating or mixing elements of pantheism (that God is identical to the universe) and deism (that the creator-god who designed the universe no longer exists in a status where he can be reached, and can instead be confirmed only by reason). It is therefore most particularly "the belief that God precedes the universe and is the universe's creator, [and] that the universe is currently the entirety of God", with some adding the contention that "the universe will one day coalesce back into a single being, God".
