It is not easy to express this enormous inversion which I have here tried to suggest in the image of a world turned inside out. I mean that the thing which had been stared at as a small something swells out and swallows everything. Christendom is in the literal sense a continent. We come to feel that it contains everything, even the things in revolt against itself. But it is perhaps the most towering intellectual transformation of all and the one that it is hardest to undo even for the sake of argument. It is almost impossible even in imagination to reverse that reversal. Another way of putting it is to say that we have come to regard all these historical figures as characters in Catholic history, even if they are not Catholics. And in a certain sense, the historical as distinct from the theological sense, they never do cease to be Catholic. They are not people who have really created something entirely new, until they actually pass the border of reason and create more or less crazy nightmares. But nightmares do not last; and most of them even now are in various stages of waking up. Protestants are Catholics gone wrong; that is what is really meant by saying they are Christians. Sometimes they have gone very wrong; but not often have they gone right ahead with their own particular wrong. Thus a Calvinist is a Catholic obsessed with the Catholic idea of the sovereignty of God. But when he makes it mean that God wishes particular people to be damned, we may say with all restraint that he has become a rather morbid Catholic. In point of fact he is a diseased Catholic; and the disease left to itself would be death or madness. But, as a matter of fact, the disease did not last long, and is itself now practically dead. But every step he takes back towards humanity is a step back towards Catholicism. Thus a Quaker is a Catholic obsessed with the Catholic idea of gentle simplicity and truth. But when he made it mean that it is a lie to say “you” and an act of idolatry to take off your hat to a lady, it is not too much to say that whether or not he had a hat off, he certainly had a tile loose. But as a matter of fact he himself found it necessary to dispense with the eccentricity (and the hat) and to leave the straight road that would have led him to a lunatic asylum. Only every step he takes back towards common sense is a step back towards Catholicism. In so far as he was right he was a Catholic; and in so far as he was wrong he has not himself been able to remain a Protestant.
