The creed was like a key in three respects; which can be most conveniently summed up under this symbol. First, a key is above all things a thing with a shape. It is a thing that depends entirely upon keeping its shape. The Christian creed is above all things the philosophy of shapes and the enemy of shapelessness. That is where it differs from all that formless infinity, Manichean or Buddhist, which makes a sort of pool of night in the dark heart of Asia; the ideal of uncreating all the creatures. That is where it differs also from the analogous vagueness of mere evolutionism; the idea of creatures constantly losing their shape. A man told that his solitary latchkey had been melted down with a million others into a Buddhistic unity would be annoyed. But a man told that his key was gradually growing and sprouting in his pocket, and branching into new wards or complications, would not be more gratified.

Second, the shape of a key is in itself a rather fantastic shape. A savage who did not know it was a key would have the greatest difficulty in guessing what it could possibly be. And it is fantastic because it is in a sense arbitrary. A key is not a matter of abstractions; in that sense a key is not a matter of argument. It either fits the lock or it does not. It is useless for men to stand disputing over it, considered by itself; or reconstructing it on pure principles of geometry or decorative art. It is senseless for a man to say he would like a simpler key; it would be far more sensible to do his best with a crowbar. And thirdly, as the key is necessarily a thing with a pattern, so this was one having in some ways a rather elaborate pattern. When people complain of the religion being so early complicated with theology and things of the kind, they forget that the world had not only got into a hole, but had got into a whole maze of holes and corners. The problem itself was a complicated problem; it did not in the ordinary sense merely involve anything so simple as sin. It was also full of secrets, of unexplored and unfathomable fallacies, of unconscious mental diseases, of dangers in all directions. If the faith had faced the world only with the platitudes about peace and simplicity some moralists would confine it to, it would not have had the faintest effect on that luxurious and labyrinthine lunatic asylum. What it did do we must now roughly describe; it is enough to say here that there was undoubtedly much about the key that seemed complex; indeed there was only one thing about it that was simple. It opened the door.

There are certain recognised and accepted statements in this matter which may for brevity and convenience be described as lies. We have all heard people say that Christianity arose in an age of barbarism. They might just as well say that Christian Science arose in an age of barbarism. They may think Christianity was a symptom of social decay, as I think Christian Science a symptom of mental decay. They may think Christianity a superstition that ultimately destroyed a civilisation, as I think Christian Science a superstition capable (if taken seriously) of destroying any number of civilisations. But to say that a Christian of the fourth or fifth centuries was a barbarian living in a barbarous time is exactly like saying that Mrs. Eddy was a Red Indian. And if I allowed my constitutional impatience with Mrs. Eddy to impel me to call her a Red Indian, I should incidentally be telling a lie. We may like or dislike the imperial civilisation of Rome in the fourth century; we may like or dislike the industrial civilisation of America in the nineteenth century; but that they both were what we commonly mean by a civilisation no person of common sense could deny if he wanted to. This is a very obvious fact, but it is also a very fundamental one; and we must make it the foundation of any further description of constructive Christianity in the past. For good or evil, it was pre-eminently the product of a civilised age, perhaps of an over-civilised age. This is the first fact apart from all praise or blame; indeed I am so unfortunate as not to feel that I praise a thing when I compare it to Christian Science. But it is at least desirable to know something of the savour of a society in which we are condemning or praising anything; and the science that connects Mrs. Eddy with tomahawks or the Mater Dolorosa with totems may for our general convenience be eliminated. The dominant fact, not merely about the Christian religion, but about the whole pagan civilisation, was that which has been more than once repeated in these pages. The Mediterranean was a lake in the real sense of a pool; in which a number of different cults or cultures were, as the phrase goes, pooled. Those cities facing each other round the circle of the lake became more and more one cosmopolitan culture. On its legal and military side it was the Roman Empire; but it was very many-sided. It might be called superstitious in the sense that it contained a great number of varied superstitions; but by no possibility can any part of it be called barbarous.

In this level of cosmopolitan culture arose the Christian religion and the Catholic Church; and everything in the story suggests that it was felt to be something new and strange. Those who have tried to suggest that it evolved out of something much milder or more ordinary have found that in this case their evolutionary method is very difficult to apply. They may suggest that Essenes or Ebionites or such things were the seed; but the seed is invisible; the tree appears very rapidly full-grown; and the tree is something totally different. It is certainly a Christmas tree in the sense that it keeps the kindliness and moral beauty of the story of Bethlehem; but it was as ritualistic as the seven-branched candlestick, and the candles it carried were considerably more than were probably permitted by the first prayer-book of Edward the Sixth. It might well be asked, indeed, why any one accepting the Bethlehem tradition should object to golden or gilded ornament since the Magi themselves brought gold; why he should dislike incense in the church since incense was brought even to the stable. But these are controversies that do not concern me here. I am concerned only with the historical fact, more and more admitted by historians, that very early in its history this thing became visible to the civilisation of antiquity; and that already the Church appeared as a Church; with everything that is implied in a Church and much that is disliked in a Church. We will discuss in a moment how far it was like other ritualistic or magical or ascetical mysteries in its own time. It was certainly not in the least like merely ethical and idealistic movements in our time. It had a doctrine; it had a discipline; it had sacraments; it had degrees of initiation; it admitted people and expelled people; it affirmed one dogma with authority and repudiated another with anathemas. If all these things be the marks of Antichrist, the reign of Antichrist followed very rapidly upon Christ.

Those who maintain that Christianity was not a Church but a moral movement of idealists have been forced to push the period of its perversion or disappearance further and further back. A bishop of Rome writes claiming authority in the very lifetime of St. John the Evangelist; and it is described as the first papal aggression. A friend of the Apostles writes of them as men he knew, and says they taught him the doctrine of the Sacrament; and Mr. Wells can only murmur that the reaction towards barbaric blood-rites may have happened rather earlier than might be expected. The date of the Fourth Gospel, which at one time was steadily growing later and later, is now steadily growing earlier and earlier; until critics are staggered at the dawning and dreadful possibility that it might be something like what it professes to be. The last limit of an early date for the extinction of true Christianity has probably been found by the latest German professor whose authority is invoked by Dean Inge. This learned scholar says that Pentecost was the occasion for the first founding of an ecclesiastical, dogmatic and despotic Church utterly alien to the simple ideals of Jesus of Nazareth. This may be called, in a popular as well as a learned sense, the limit. What do professors of this kind imagine that men are made of? Suppose it were a matter of any merely human movement, let us say that of the Conscientious Objectors. Some say the early Christians were Pacifists; I do not believe it for a moment; but I am quite ready to accept the parallel for the sake of the argument. Tolstoy or some great preacher of peace among peasants has been shot as a mutineer for defying conscription; and a month or so after his few followers meet together in an upper room in remembrance of him. They never had any reason for coming together except that common memory; they are men of many kinds with nothing to bind them, except that the greatest event in all their lives was this tragedy of the teacher of universal peace. They are always repeating his words, revolving his problems, trying to imitate his character. The Pacifists meet at their Pentecost and are possessed of a sudden ecstasy of enthusiasm and wild rush of the whirlwind of inspiration, in the course of which they proceed to establish universal Conscription, to increase the Navy Estimates, to insist on everybody going about armed to the teeth and on all the frontiers bristling with artillery; the proceedings concluding with the singing of ‘Boys of the Bulldog Breed’ and ‘Don’t let them scrap the British Navy.’ That is something like a fair parallel to the theory of these critics; that the transition from their idea of Jesus to their idea of Catholicism could have been made in the little upper room at Pentecost. Surely anybody’s common sense would tell him that enthusiasts, who only met through their common enthusiasm for a leader whom they loved, would not instantly rush away to establish everything that he hated. No, if the ‘ecclesiastical and dogmatic system’ is as old as Pentecost it is as old as Christmas. If we trace it back to such very early Christians we must trace it back to Christ.

We may begin then with these two negations. It is nonsense to say that the Christian faith appeared in a simple age; in the sense of an unlettered and gullible age. It is equally nonsense to say that the Christian faith was a simple thing; in the sense of a vague or childish or merely instinctive thing. Perhaps the only point in which we could possibly say that the Church fitted into the pagan world is the fact that they were both not only highly civilised but rather complicated. They were both emphatically many-sided; but antiquity was then a many-sided hole, like a hexagonal hole waiting for an equally hexagonal stopper. In that sense only the Church was many-sided enough to fit the world. The six sides of the Mediterranean world faced each other across the sea and waited for something that should look all ways at once. The Church had to be both Roman and Greek and Jewish and African and Asiatic. In the very words of the Apostle of the Gentiles, it was indeed all things to all men. Christianity then was not merely crude and simple, and was the very reverse of the growth of a barbaric time. But when we come to the contrary charge, we come to a much more plausible charge. It is very much more tenable that the Faith was but the final phase of the decay of civilisation, in the sense of the excess of civilisation; that this superstition was a sign that Rome was dying, and dying of being much too civilised. That is an argument much better worth considering; and we will proceed to consider it.

At the beginning of this book I ventured on a general summary of it, in a parallel between the rise of humanity out of nature and the rise of Christianity out of history. I pointed out that in both cases what had gone before might imply something coming after; but did not in the least imply what did come after. If a detached mind had seen certain apes it might have deduced more anthropoids; it would not have deduced man or anything within a thousand miles of what man has done. In short, it might have seen Pithacanthropus or the Missing Link looming in the future, if possible almost as dimly and doubtfully as we see him looming in the past. But if it foresaw him appearing it would also foresee him disappearing, and leaving a few faint traces just as he has left a few faint traces; if they are traces. To foresee that Missing Link would not be to foresee Man, or anything like Man. Now this earlier explanation must be kept in mind; because it is an exact parallel to the true view of the Church; and the suggestion of it having evolved naturally out of the Empire in decay.

The truth is that in one sense a man might very well have predicted that the imperial decadence would produce something like Christianity. That is, something a little like and gigantically different. A man might very well have said, for instance, ‘Pleasure has been pursued so extravagantly that there will be a reaction into pessimism. Perhaps it will take the form of asceticism; men will mutilate themselves instead of merely hanging themselves.’ Or a man might very reasonably have said, ‘If we weary of our Greek and Latin gods we shall be hankering after some eastern mystery or other; there will be a fashion in Persians or Hindoos.’ Or a man of the world might well have been shrewd enough to say, ‘Powerful people are picking up these fads; some day the court will adopt one of them and it may become official.’ Or yet another and gloomier prophet might be pardoned for saying, ‘The world is going down-hill; dark and barbarous superstitions will return, it does not matter much which. They will all be formless and fugitive like dreams of the night.’

Now it is the intense interest of the case that all these prophecies were really fulfilled; but it was not the Church that fulfilled them. It was the Church that escaped from them, confounded them, and rose above them in triumph. In so far as it was probable that the mere nature of hedonism would produce a mere reaction of asceticism, it did produce a mere reaction of asceticism. It was the movement called Manichean, and the Church was its mortal enemy. In so far as it would have naturally appeared at that point of history, it did appear; it did also disappear, which was equally natural. The mere pessimist reaction did come with the Manichees and did go with the Manichees. But the Church did not come with them or go with them; and she had much more to do with their going than with their coming. Or again, in so far as it was probable that even the growth of scepticism would bring in a fashion of eastern religion, it did bring it in; Mithras came from far beyond Palestine out of the heart of Persia, bringing strange mysteries of the blood of bulls. Certainly there was everything to show that some such fashion would have come in any case. But certainly there is nothing in the world to show that it would not have passed away in any case. Certainly an Oriental fad was something eminently fitted to the fourth or fifth century; but that hardly explains it having remained to the twentieth century, and still going strong. In short, in so far as things of the kind might have been expected then, things like Mithraism were experienced then; but it scarcely explains our more recent experiences. And if we were still Mithraists merely because Mithraic head-dresses and other Persian apparatuses might be expected to be all the rage in the days of Domitian, it would almost seem by this time that we must be a little dowdy.

It is the same, as will be suggested in a moment, with the idea of official favouritism. In so far as such favouritism shown towards a fad was something that might have been looked for during the decline and fall of the Roman Empire, it was something that did exist in that Empire and did decline and fall with it. It throws no sort of light on the thing that resolutely refused to decline and fall; that grew steadily while the other was declining and falling; and which even at this moment is going forward with fearless energy, when another aeon has completed its cycle and another civilisation seems almost ready to fall or to decline.
