"The idea that any one of our religions represents the infallible word of the One True God requires an encyclopedic ignorance of history, mythology, and art even to be entertained--as the beliefs, rituals, and iconography of each of our religions attest to centuries of cross-pollination among them. Whatever their imagined source, the doctrines of modern religions are no more tenable than those which, for lack of adherents, were cast upon the scrap heap of mythology millennia ago; for there is no more evidence to justify a belief in the literal existence of Yahweh and Satan than there was to keep Zeus perched upon his mountain throne or Poseidon churning the seas."
