“When one gives up Christian belief one thereby deprives oneself of the right to Christian morality… Christianity is a system, a consistently thought out and complete view of things. If one breaks out of it a fundamental idea, the belief in God, one thereby breaks the whole thing to pieces: one has nothing of any consequence left in one’s hand… Christian morality is a command: its origin is transcendental… it possesses truth only if God is truth – it stands or falls with the belief in God.”
