There may be a theology without the Scriptures — a theology of nature, gathered by painful, and slow, and sometimes doubtful processes from what man sees around him in external nature and the course of history, and what he sees within him of nature and of grace. In like manner there may be and has been an astronomy of nature, gathered by man in his natural state without help from aught but his naked eyes, as he watched in the fields by night. But what is this astronomy of nature to the astronomy that has become possible through the wonderful appliances of our observatories? The Word of God is to theology as, but vastly more than, these instruments are to astronomy. It is the instrument which so far increases the possibilities of the science as to revolutionize it and to place it upon a height from which it can never more descend. What would be thought of the deluded man, who, discarding the new methods of research, should insist on acquiring all the astronomy which he would admit, from the unaided observation of his own myopic and astigmatic eyes? Much more deluded is he who, neglecting the instrument of God’s Word written, would confine his admissions of theological truth to what he could discover from the broken lights that play upon external nature, and the faint gleams of a dying or even a slowly reviving light, which arise in his own sinful soul. Ah, no! The telescope first made a real science of astronomy possible: and the Scriptures form the only sufficing source of theology.
If you leave off looking at books about beasts and men, if you begin to look at beasts and men then (if you have any humour or imagination, any sense of the frantic or the farcical) you will observe that the startling thing is not how like man is to the brutes, but how unlike he is. It is the monstrous scale of his divergence that requires an explanation. That man and brute are like is, in a sense, a truism; but that being so like they should then be so insanely unlike, that is the shock and the enigma. That an ape has hands is far less interesting to the philosopher than the fact that having hands he does next to nothing with them; does not play knuckle-bones or the violin; does not carve marble or carve mutton. People talk of barbaric architecture and debased art. But elephants do not build colossal temples of ivory even in a roccoco style; camels do not paint even bad pictures, though equipped with the material of many camel's-hair brushes. Certain modern dreamers say that ants and bees have a society superior to ours. They have, indeed, a civilization; but that very truth only reminds us that it is an inferior civilization. Who ever found an ant-hill decorated with the statues of celebrated ants? Who has seen a bee-hive carved with the images of gorgeous queens of old? No; the chasm between man and other creatures may have a natural explanation, but it is a chasm. We talk of wild animals; but man is the only wild animal. It is man that has broken out. All other animals are tame animals; following the rugged respectability of the tribe or type. All other animals are domestic animals; man alone is ever undomestic, either as a profligate or a monk. So that this first superficial reason for materialism is, if anything, a reason for its opposite; it is exactly where biology leaves off that all religion begins.
I remember once when I had been giving a talk to the R.A.F., an old, hard-bitten officer got up and said, ‘I’ve no use for all that stuff. But, mind you, I’m a religious man too. I know there’s a God. I’ve felt Him: out alone in the desert at night: the tremendous mystery. And that’s just why I don’t believe all your neat little dogmas and formulas about Him. To anyone who’s met the real thing they all seem so petty and pedantic and unreal!’Now in a sense I quite agreed with that man. I think he had probably had a real experience of God in the desert. And when he turned from that experience to the Christian creeds, I think he really was turning from something real to something less real. In the same way, if a man has once looked at the Atlantic from the beach, and then goes and looks at a map of the Atlantic, he also will be turning from something real to something less real: turning from real waves to a bit of coloured paper. But here comes the point. The map is admittedly only coloured paper, but there are two things you have to remember about it. In the first place, it is based on what hundreds and thousands of people have found out by sailing the real Atlantic. In that way it has behind it masses of experience just as real as the one you could have from the beach; only, while yours would be a single glimpse, the map fits all those different experiences together. In the second place, if you want to go anywhere, the map is absolutely necessary. As long as you are content with walks on the beach, your own glimpses are far more fun than looking at a map. But the map is going to be more use than walks on the beach if you want to get to America.
