That is perhaps the mightiest of the mysteries of the cave It is already apparent that though men are said to have looked for hell under the earth, in this case it is rather heaven that is under the earth and there follows in this strange story the idea of an upheaval of heaven. That is the paradox of the whole position; that henceforth the highest thing can only work from below. Royalty can only return to its own by a sort of rebellion. Indeed the Church from its beginnings, and perhaps especially in its beginnings, was not so much a principality as a revolution against the prince of the world. This sense that the world had been conquered by the great usurper, and was in his possession, has been much deplored or derided by those optimists who identify enlightenment with ease. But it was responsible for all that thrill of defiance and a beautiful danger that made the good news seem to be really both good and new. It was in truth against a huge unconscious usurpation that it raised a revolt, and originally so obscure a revolt. Olympus still occupied the sky like a motionless cloud moulded into many mighty forms; philosophy still sat in the high places and even on the thrones of the kings, when Christ was born in the cave and Christianity in the catacombs. In both cases we may remark the same paradox of revolution; the sense of something despised and of something feared.
—G. K. Chesterton, The Everlasting Man
