It was Dostoevsky, once again, who drew from the French Revolution and its seeming hatred of the Church the lesson that "revolution must necessarily begin with atheism." That is absolutely true. But the world had never before known a godlessness as organized, militarized, and tenaciously malevolent as that practiced by Marxism. Within the philosophical system of Marx and Lenin, and at the heart of their psychology, hatred of God is the principal driving force, more fundamental than all their political and economic pretensions. Militant atheism is not merely incidental or marginal to Communist policy; it is not a side effect, but the central pivot.
