Profound as the teaching of this narrative is, its meaning does not lie on the surface. Literal interpretation will reach a measure of its significance, but plainly there is more here than appears in the letter. When we read that the serpent was more subtile than any beast of the field which the Lord God had made, and that he tempted the woman, we at once perceive that it is not with the outer husk of the story we are to concern ourselves, but with the kernel. The narrative throughout speaks of nothing but the brute serpent; not a word is said of the devil, not the slightest hint is given that the machinations of a fallen angel are signified. The serpent is compared to the other beasts of the field, showing that it is the brute serpent that is spoken of. The curse is pronounced on the beast, not on a fallen spirit summoned for the purpose before the Supreme; and not in terms which could apply to a fallen spirit, but in terms that are applicable only to the serpent that crawls. Yet every reader feels that this is not the whole mystery of the fall of man: moral evil cannot be accounted for by referring it to a brute source. No one, I suppose, believes that the whole tribe of serpents crawl as a punishment of an offence committed by one of their number, or that the whole iniquity and sorrow of the world are due to an actual serpent. Plainly this is merely a pictorial representation intended to convey some general impressions and ideas. Vitally important truths underlie the narrative and are bodied forth by it; but the way to reach these truths is not to adhere too rigidly to the literal meaning, but to catch the general impression which it seems fitted to make.
No doubt this opens the door to a great variety of interpretation. No two men will attach to it precisely the same meaning. One says, the serpent is a symbol for Satan, but Adam and Eve are historical persons. Another says, the tree of the knowledge of good and evil is a figure, but the driving out from the garden is real. Another maintains that the whole is a picture, putting in a visible, intelligible shape certain vitally important truths regarding the history of our race. So that every man is left very much to his own judgment, to read the narrative candidly and in such light from other sources as he has, and let it make its own impression upon him. This would be a sad result if the object of the Bible were to bring us all to a rigid uniformity of belief in all matters; but the object of the Bible is not that, but the far higher object of furnishing all varieties of men with sufficient light to lead them to God. And this being so, variety of interpretation in details is not to be lamented. The very purpose of such representations as are here given is to suit all stages of mental and spiritual advancement. Let the child read it and he will learn what will live in his mind and influence him all his life. Let the devout man who has ranged through all science and history and philosophy come back to this narrative, and he feels that he has here the essential truth regarding the beginnings of man's tragical career upon earth.
