Sometimes we need to go back to the great minds in order to put truths into their context, and see them in proportion to one another. In that respect, no-one has captured more dramatically what was actually going on at the first Christmas than G.K. Chesterton in this startling passage from “The Everlasting Man” published in 1925:
We all know the story of how Herod, alarmed at some rumor of a mysterious rival, remembered the wild gesture of the capricious despots of Asia and ordered a massacre of suspects of the new generation of the populace. Everyone knows the story; but not everyone has perhaps noted its place in the story of the strange religions of men. Not everybody has seen the significance even of its very contrast with the Corinthian columns and Roman pavement of that conquered and superficially civilized world. Only, as the purpose in his dark spirit began to show and shine in the eyes of the Idumean, a seer might perhaps have seen something like a great grey ghost that looked over his shoulder; have seen behind him filling the dome of night and hovering for the last time over history, that vast and fearful fact that was Moloch of the Carthaginians; awaiting his last tribute from a ruler of the races of Shem. The demons, in that first festival of Christmas, feasted also in their own fashion.
Unless we understand the presence of that enemy, we shall not only miss the point of Christianity, but even miss the point of Christmas. Christmas for us in Christendom has become one thing, and in one sense even a simple thing. But like all the truths of that tradition, it is in another sense a very complex thing. Its unique note is the simultaneous striking of many notes; of humility, of gaiety, of gratitude, of mystical fear, but also of vigilance and of drama. It is not only an occasion for the peacemakers any more than for the merry makers; it is not only a Hindu peace conference any more than it is only a Scandinavian winter feast. There is something defiant in it also; something that makes the abrupt bells at midnight sound like the great guns of a battle that has just been won. All this indescribable thing that we call the Christmas atmosphere only bangs in the air as something like a lingering fragrance or fading vapor from the exultant, explosion of that one hour in the Judean hills nearly two thousand years ago. But the savor is still unmistakable, and it is something too subtle or too solitary to be covered by our use of the word peace. By the very nature of the story, the rejoicings in the cavern were rejoicings in a fortress or an outlaws den; properly understood it is not unduly flippant to say they were rejoicing in a dug-out.
It is not only true that such a subterranean chamber was a hiding-place from enemies; and that the enemies were already scouring the stony plain that lay above it like a sky. It is not only that the very horse-hoofs of Herod might in that sense have passed like thunder over the sunken head of Christ. It is also that there is in that image a true idea of an outpost, of a piercing through the rock and an entrance into an enemy territory. There is in this buried divinity an idea of undermining the world; of shaking the towers and palaces from below; even as Herod the great king felt that earthquake under him and swayed with his swaying palace.
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 molded 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.
