Let me conclude with a warning first issued by one of Western civilization’s greatest atheists, the German philosopher Friedrich Nietzsche. The ideas that define Western civilization, Nietzsche said, are based on Christianity. Because some of these ideas seem to have taken on a life of their own, we might have the illusion that we can abandon Christianity while retaining them. This illusion, Nietzsche warns us, is just that. Remove Christianity and the ideas fall too.
Consider the example of Europe, where secularization has been occurring for well over a century. For a while it seemed that secularization would have no effect on European morality or social institutions. Yet increasingly today there is evidence of the decline of the nuclear family. Overall birthrates have plummeted, while rates of divorce and out-of-wedlock births are up.
Nietzsche also warned that, with the decline of Christianity, new and opposing ideas would arise. We see these today in demands for the radical redefinition of the family, the revival of eugenic theories, and even arguments for infanticide.
In sum, the eradication of Christianity—and of organized religion in general—would also mean the gradual extinction of the principles of human dignity. Consider human equality. Why do we hold to it? The Christian idea of equality in God’s eyes is undeniably largely responsible. The attempt to ground respect for equality on a purely secular basis ignores the vital contribution by Christianity to its spread. It is folly to believe that it could survive without the continuing aid of religious belief.
If we cherish what is distinctive about Western civilization, then—whatever our religious convictions—we should respect rather than denigrate its Christian roots.
