It’s sad that a long-dead atheist could be a prophet about the causes of the decline of Western Christianity...
[Frederick Nietzsche] had the good manners to despise Christianity, in large part, for what it actually was–above all, for its devotion to an ethics of compassion–rather than allow himself the soothing, self-righteous fantasy that Christianity’s history had been nothing but an interminable pageant of violence, tyranny, and sexual neurosis. He may have hated many Christians for their hypocrisy, but he hated Christianity itself principally on account of its enfeebling solicitude for the weak, the outcast, the infirm, and the diseased; and, because he was conscious of the historical contingency of all cultural values, he never deluded himself that humanity could do away with Christian faith while simply retaining Christian morality in some diluted form, such as liberal social conscience or innate human sympathy.”
– David Bentley Hart, ‘Atheist Delusions’
“When one gives up the Christian faith, one pulls the right to Christian morality out from under one’s feet. This morality is by no means self-evident: this point has to be exhibited again and again, despite the English flatheads. Christianity is a system, a whole view of things thought out together. By breaking one main concept out of it, the faith in God, one breaks the whole: nothing necessary remains in one’s hands. Christianity presupposes that man does not know, cannot know, what is good for him, what evil: he believes in God, who alone knows it. Christian morality is a command; its origin is transcendent; it is beyond all criticism, all right to criticism; it has truth only if God has truth - it stands or falls with faith in God.”
- Friedrich Nietzsche, Twilight of the Idols (1889)
