seeing through. Christianity remained the official religion of a Renaissance prince or the official religion of an eighteenth-century bishop, just as an ancient mythology remained the official religion of Julius Caesar or the Arian creed long remained the official religion of Julian the Apostate. But there was a difference between the cases of Julius and of Julian; because the Church had begun its strange career. There was no reason why men like Julius should not worship gods like Jupiter forever in public and laugh at them forever in private. But when Julian treated Christianity as dead, he found it had come to life again. He also found, incidentally, that there was not the faintest sign of Jupiter ever coming to life again. This case of Julian and the episode of Arianism is but the first of a series of examples that can only be roughly indicated here. Arianism, as has been said, had every human appearance of being the natural way in which that particular superstition of Constantine might be expected to peter out. All the ordinary stages had been passed through; the creed had become a respectable thing, had become a ritual thing, had then been modified into a rational thing; and the rationalists were ready to dissipate the last remains of it, just as they do today. When Christianity rose again suddenly and threw them, it was almost as unexpected as Christ rising from the dead. But there are many other examples of the same thing, even about the same time. The rush of missionaries from Ireland, for instance, has all the air of an unexpected onslaught of young men on an old world, and even on a Church that showed signs of growing old. Some of them were martyred on the coast of Cornwall; and the chief authority on Cornish antiquities told me that he did not believe for a moment that they were martyred by heathens but (as he expressed it with some humour) “by rather slack Christians.”
Now if we were to dip below the surface of history, as it is not in the scope of this argument to do, I suspect that we should find several occasions when Christendom was thus to all appearance hollowed out from within by doubt and indifference, so that only the old Christian shell stood as the Pagan shell had stood so long. But the difference is that
