And, I think, if you wish me to say what I think, that, humanly speaking, Catholicism will decrease rapidly now.

It is perfectly true that Protestantism is dead.

Men do recognise at last that a supernatural Religion involves an absolute authority, and that Private Judgment in matters of faith is nothing else than the beginning of disintegration.
And it is also true that since the Catholic Church is the only institution that even claims supernatural authority, with all its merciless logic, she has again the allegiance of practically all Christians who have any supernatural belief left.

There are a few faddists left, especially in America and here; but they are negligible.
That is all very well; but, on the other hand, you must remember that Humanitarianism, contrary to all persons' expectations, is becoming an actual religion itself, though anti-supernatural.

It is Pantheism; it is developing a ritual under Freemasonry; it has a creed, 'God is Man,' and the rest.
