It seems to me impossible for a civilized man to love or worship, or respect the God of the Old Testament. A really civilized man, a really civilized woman, must hold such a God in abhorrence and contempt... In the New Testament, death is not the end, but the beginning of punishment that has no end. In the New Testament the malice of God is infinite and the hunger of his revenge eternal... This frightful dogma, this infinite lie, made me the implacable enemy of Christianity. The truth is that this belief in eternal pain has been the real persecutor.
