To defend something is always to disparage it. Suppose that someone has a warehouse full of gold, and suppose he is willing to give every ducat to the poor – but in addition, suppose he is stupid enough to begin this charitable enterprise of his with a defense in which he justifies it on three grounds: people will almost come to doubt that he is doing any good. As for Christianity! Well, he who defends it has never believed it. If he believes, then the enthusiasm of faith is not a defense – no, it is an attack and victory; a believer is a victor.
