Could any form of theism ever be stated as a lack of belief? For example, if your idea of God was an abstract being who exists necessarily and only moves at will in the sense of complete freedom, and as opposed to being necessitated by antecedents, could you ever frame your position as something such as a lack of belief in material causation for the Universe, or as a lack of belief in eternal physical bodies, (taking the universe to be a body), or infinite motion, or something of that sort? Or does theism necessarily, even in the vaguest sense, entail certain doctrines that atheism does not?
He who loves God cannot endeavour that God should love him in return - Baruch Spinoza
