I suppose that Faith is really another face of Hope, it's not identical, but very few individuals have done something in the faith that something bad would happen to them for doing it.
Most Religion is based on the idea of a reward after you die, or a punishment, Atheism believes neither, so cannot really be counted a Religious belief.
I suppose what is so blood chillingly terrifying is not Religion itself, it's the possiblities it represents. Whatever happens after you die is, according to the Church, eternal, and it is also they who dictate what God thinks, and where the up and down buttons are in the lift. Gods thoughts may be pure, but you can be damn certain that not every person who has dictated Church, and therefore Gods, policies over the years has been. Personally, I think as far as eternity is concerned, I'd rather trust myself than a man in a funny hat.
