Deism

Tom Paine:

Its creed is pure and sublimely simple. It believes in God and there it rests. It honours Reason [and] it avoids all presumptuous beliefs and rejects, as the fabulous inventions of men, all books pretending to revelation.

Sounds pretty good to me. I've never been entirely comfortable with atheism, but I can't stand structured religion either.
