I call Christianity the one great curse, the one great intrinsic depravity, the one great instinct for revenge for which no expedient is sufficiently poisonous, secret, subterranean, petty - I call it the one mortal blemish of mankind

Christianity gave Eros poison to drink: he did not die of it but degenerated - into vice

Assuming that he believes at all, the everyday Christian is a pitiful figure, a man who really cannot count up to three, and who besides, precisely because of his mental incompetence, would not deserve such a punishment as Christianity promises him

Two great European narcotics, alcohol and Christianity

This indictment of Christianity I will write on all walls, wherever there are walls - I have letters to make even the blind see

It was Christianity which first painted the devil on the worlds wall; It was Christianity which first brought sin into the world. Belief in the cure which it offered has now been shaken to it's deepest roots; but belief in the sickness which it taught and propagated continues to exist'.
