The great majority of Protestant bodies today, whether they are strong or weak, are not strengthened . . . by the actual attraction of their new followers to their old doctrines. A young man will suddenly become a Catholic priest, or even a Catholic monk, because he has a spontaneous and even impatient personal enthusiasm for the doctrine of Virginity as it appeared to St. Catherine or St. Clare. But how many men become Baptist ministers because they have a personal horror of the idea of an innocent infant coming unconsciously to Christ? How many honest Presbyterian ministers in Scotland really want to go back to John Knox, as a Catholic mystic might want to go back to John of the Cross? These men inherit positions which they feel they can hold with reasonable consistency and general agreement; but they do inherit them. For them religion is tradition. We Catholics naturally do not sneer at tradition; but we say that in this case it is really tradition and nothing else. Not one man in a hundred of these people would ever have joined his present communion if he had been born outside it. Not one man in a thousand of them would have invented anything like his church formulas if they had not been laid down for him. None of them has any real reason for being in their own particular church, whatever good reason they may still have for being outside ours. In other words, the old creed of their communion has ceased to function as a fresh and stimulating idea. It is at best a motto or a war cry and at the worst a catchword. But it is not meeting contemporary ideas like a contemporary idea. In their time and in their turn we believe that those other contemporary ideas will also prove their mortality by having also become mottoes and catchwords and traditions. A century or two hence Spiritualism may be a tradition and Socialism may be a tradition and Christian Science may be a tradition. But Catholicism will not be a tradition. It will still be a nuisance and a new and dangerous thing. –from The Catholic Church and Conversion (1926)
