Christendom has had a series of revolutions and in each one of them Christianity has died. Christianity has died many times and risen again; for it had a God who knew the way out of the grave. But the first extraordinary fact which marks this history is this: that Europe has been turned upside down over and over again; and that at the end of each of these revolutions the same religion has again been found on top. The Faith is always converting the age, not as an old religion but as a new religion.
