A God of love, a God of wrath, a God of jealousy, a God of bigotry, a God of vulgar tirades, a God of cheating and lying — yes, the Christian God is given all of these characteristics, and isn’t it a wretched mess to be offered to men in this twentieth century? The beginning of wisdom, the beginning of humanism, the beginning of progress is the rejection of this absurd, extravagantly impossible myth of a God.

— E. Haldeman-Julius
