One of the most terrifying of contemporary phenomena is the emergence of virulent anti-semitism, not in Germany or in Italy, not under this or that political regime, but within the Church. It is terrifying; because it means that the devil is active in the Church in a way for which there is perhaps no previous parallel. Evil has always been active in the Church; but it has taken the form of lust, avarice, ambition, pride. This is something far worse. The essence of Christianity is love, and understanding based on love. The essence of ideological anti-semitism is hatred, and stupidity based on hatred. One was shown recently some leaflets written, according to their own testimony, by a Catholic, and urging Catholics to unite against the Jews and their threat of world domination. They made painful reading because of their extraordinary vulgarity. But they were terrifying because of the sheer violence of hatred they revealed. One felt that one was looking at the naked face of evil. Suppose that the author of these leaflets were right in his contention that world Jewry is plotting to dominate the world, to destroy Christendom; there could still be no excuse for tearing the Christian faith to shreds in a way that no outside force, Jewish or otherwise, could ever begin to do. To disseminate this poison in the name of Christ is a betrayal that is only possible to a Christian. But in face of such a betrayal, all calamities to the Church from without are negligible.
