Actually, there is a "denomination" of Christianity that is completely non-exclusivist, the Society of Friends (Quakers). Their faith is based on experience rather than reason (though they're not anti-rational) or the desire to maximize their power / influence as individuals or as a group.

The Epicurean paradox / flow chart, like most paradoxes, is about the limits of natural language to account for phenomena in the world (along the lines of "If God is all-powerful, can he make a rock that is so heavy he can't lift it?")
