"It is in Christianity that our arts have developed; it is in Christianity that the laws of Europe have—until recently—been rooted. It is against a background of Christianity that all our thought has significance. An individual European may not believe that the Christian Faith is true, and yet what he says, and makes, and does, will all spring out of his heritage of Christian culture and depend upon that culture for its meaning. Only a Christian could have reproduced a Voltaire or a Nietzsche. I do not believe that the culture of Europe could survive the complete disappearance of the Christian Faith."
