For those who think the idea of the Crusade is one that spoils the idea of the Cross, we can only say that for them the idea of the Cross is spoiled; the idea of the cross is spoiled quite literally in the cradle. It is not here to the purpose to argue with them on the abstract ethics of fighting; the purpose in this place is merely to sum up the combination of ideas that make up the Christian and Catholic idea, and to note that all of them are already crystallised in the first Christmas story. They are three distinct and commonly contrasted things which are nevertheless one thing; but this is the only thing which can make them one.
The first is the human instinct for a heaven that shall be as literal and almost as local as a home. It is the idea pursued by all poets and pagans making myths; that a particular place must be the shrine of the god or the abode of the blest; that fairyland is a land; or that the return of the ghost must be the resurrection of the body. I do not here reason about the refusal of rationalism to satisfy this need. I only say that if the rationalists refuse to satisfy it, the pagans will not be satisfied. This is present in the story of Bethlehem and Jerusalem as it is present in the story of Delos and Delphi; and as it is not present in the whole universe of Lucretius or the whole universe of Herbert Spencer.
The second element is a philosophy larger than other philosophies; larger than that of Lucretius and infinitely larger than that of Herbert Spencer. It looks at the world through a hundred windows where the ancient stoic or the modern agnostic only looks through one. It sees life with thousands of eyes belonging to thousands of different sorts of people, where the other is only the individual standpoint of a stoic or an agnostic. It has something for all moods of man, it finds work for all kinds of men, it understands secrets of psychology, it is aware of depths of evil, it is able to distinguish between ideal and unreal marvels and miraculous exceptions, it trains itself in tact about hard cases, all with a multiplicity and subtlety and imagination about the varieties of life which is far beyond the bald or breezy platitudes of most ancient or modern moral philosophy. In a word, there is more in it; it finds more in existence to think about; it gets more out of life. Masses of this material about our many-sided life have been added since the time of St. Thomas Aquinas. But St. Thomas Aquinas alone would have found himself limited in the world of Confucius or of Comte.
And the third point is this; that while it is local enough for poetry and larger than any other philosophy, it is also a challenge and a fight. While it is deliberately broadened to embrace every aspect of truth, it is still stiffly embattled against every mode of error. It gets every kind of man to fight for it, it gets every kind of weapon to fight with, it widens its knowledge of the things that are fought for and against with every art of curiosity or sympathy; but it never forgets that it is fighting. It proclaims peace on earth and never forgets why there was war in heaven.
This is the trinity of truths symbolised here by the three types in the old Christmas story; the shepherds and the kings and that other king who warred upon the children. It is simply not true to say that other religions and philosophies are in this respect its rivals. It is not true to say that any one of them combines these characters; it is not true to say that any one of them pretends to combine them. Buddhism may profess to be equally mystical; it does not even profess to be equally military. Islam may profess to be equally military; it does not even profess to be equally metaphysical and subtle. Confucianism may profess to satisfy the need of the philosophers for order and reason; it does not even profess to satisfy the need of the mystics for miracle and sacrament and the consecration of concrete things.
There are many evidences of this presence of a spirit at once universal and unique. One will serve here which is the symbol of the subject of this chapter; that no other story, no pagan legend or philosophical anecdote or historical event, does in fact affect any of us with that peculiar and even poignant impression produced on us by the word Bethlehem. No other birth of a god or childhood of a sage seems to us to be Christmas or anything like Christmas. It is either too cold or too frivolous, or too formal and classical, or too simple and savage, or too occult and complicated. Not one of us, whatever his opinions, would ever go to such a scene with the sense that he was going home. He might admire it because it was poetical, or because it was philosophical, or any number of other things in separation; but not because it was itself. The truth is that there is a quite peculiar and individual character about the hold of this story on human nature; it is not in its psychological substance at all like a mere legend or the life of a great man. It does not exactly in the ordinary sense turn our minds to greatness; to those extensions and exaggerations of humanity which are turned into gods and heroes, even by the healthiest sort of hero-worship. It does not exactly work outwards, adventurously, to the wonders to be found at the ends of the earth. It is rather something that surprises us from behind, from the hidden and personal part of our being; like that which can some times take us off our guard in the pathos of small objects or the blind pieties of the poor. It is rather as if a man had found an inner room in the very heart of his own house, which he had never suspected; and seen a light from within. It is as if he found something at the back of his own heart that betrayed him into good. It is not made of what the world would call strong materials; or rather it is made of materials whose strength is in that winged levity with which they brush us and pass. It is all that is in us but a brief tenderness that is there made eternal; all that means no more than a momentary softening that is in some strange fashion become a strengthening and a repose; it is the broken speech and the lost word that are made positive and suspended unbroken; as the strange kings fade into a far country and the mountains resound no more with the feet of the shepherds; and only the night and the cavern lie in fold upon fold over something more human than humanity.
