Granting, however, that all we have found in the Decalogue's conception of Yahweh was present to the mind of Moses, and granting that the commands which deal with the relations of men to each other are not mere isolated prohibitions, but are founded upon moral principles which were understood even then to have much wider implications, there still remains a gap between the widest meaning that early time could put into them, and that which Luther's Catechism, or the Catechism of the Westminster Divines, for example, asserts. The question therefore arises whether these wider and more detailed explanations, which make the Decalogue cover the whole field of the moral and religious life, are legitimate, and if so, on what principle can they be justified? The reply would seem to be that they are legitimate, and that the ten words did contain much more than Moses or any of his nation for many centuries after him understood. For any fruitful thought, any thought which really penetrates the heart of things, must have in it wider implications than the first thinker of it can have conceived. If by any means a man has had insight to see the central fact of any domain of thought and life, its applications will not be limited to the comparatively few cases to which he may apply it. He will generally be content to deduce from his discovery just those conclusions which in his circumstances and in his day are practically useful and are most clamorously demanded. But those who come after, pressed by new needs, challenged by new experiences, and enlightened by new thoughts in related regions, will assuredly find that more was involved in that first step than any one had seen. The scope of the fruitful principle will thus inevitably widen with the course of things, and inferences undreamed of by those who first enunciated the principle will be securely drawn from it by later generations. Now if that be true in regard to truths discovered by the unassisted intellect of man, how much more true will it be of thoughts which have first been revealed to man under the influence of inspiration? Behind the human mind which received them and applied them to the circumstances which then had to be dealt with, there is always the infinite mind which sees that
"Far-off Divine event
To which the whole creation moves."
The Divine purpose of the revelation must be the true measure of the thoughts revealed, and the Divine purpose can best be learned by studying the results as they have actually evolved themselves in the course of ages. Consequently, while the fundamental point in sound interpretation of a book such as the Bible is to ascertain first what the statements made therein signified to those who heard them first, the second point is not to shut the mind to the wider and more extensive applications of them which the thought and experience of men, taught by the course of history, have been induced, or even compelled, to make. Both the narrower and the wider meanings are there, and were meant to be found there. No exposition which ignores either can be adequate.
That all works of God are to be dealt with in this way is beautifully demonstrated by Ruskin (Fors Clavigera, Vol. I., Letter V.). In criticising the statement of a botanist that "there is no such thing as a flower," after admitting that in a certain sense the lecturer was right, he goes on to say: "But in the deepest sense of all, he was to the extremity of wrongness wrong; for leaf and root and fruit exist, all of them, only—that there may be flowers. He disregarded the life and passion of the creature, which were its essence. Had he looked for these, he would have recognised that in the thought of nature herself, there is, in a plant, nothing else but flowers." That means, of course, that the final perfection of a development is the real and final meaning of it all. Now any thought given by God in this special manner which we call "inspiration" has in it a manifold and varied life, and an end in view, which God alone foresees. It works like leaven, it grows like a seed. It is supremely living and powerful; and though it may have begun its life, like the mustard seed, in a small and lowly sphere, it casts out branches on all sides till its entire allotted space is filled. So in the Decalogue; the central chord in all the matters dealt with has been touched with Divine skill, and all that has further to be revealed or learned on that matter must lie in the line of the first announcement.
It is not, therefore, an illegitimate extension of the meaning of the first commandment to say that it teaches monotheism, nor of the second that it teaches the spirituality of God, nor of the seventh that it forbids all sensuality in thought or word or deed. It is true that probably only the separateness of God was originally seen to be asserted in the first, and the words may possibly have been understood to mean that the "other gods" referred to had some kind of actual life. The second, too, may have seemed to be fulfilled when no earthly thing that was made by man was taken to represent Yahweh. Lastly, those who say that nothing is forbidden in the seventh commandment but literal adultery have much to say for themselves. In a polygamous society concubinage always exists. The absence of the more flagrant of what in monogamous societies are called social evils does not in the least imply the superior morality, such as many who wish to disparage our Christian civilisation have ascribed, for instance, to Mohammedans. The degraded class of women who are the reproach and the despair of our large towns are not so frequent in those societies, because all women are degraded to nearer their level than in monogamous lands. Both lust and vice are more prevalent: and they are so because the whole level of thought and feeling in regard to such matters is much lower than with us.
Now, undoubtedly, ancient Israel was no exception to this rule. In it, as a polygamous nation, there was a licence in regard to sexual relations with women who were neither married nor betrothed which would be impossible now in any Christian community. It may be, therefore, that only the married woman was specially protected by this law. But in none of these cases did the more rudimentary conception of the scope of the commandments last. By imperceptible steps the sweep of them widened, until finally the last consequences were deduced from them, and they were seen to cover the whole sphere of human duty. It may have been a long step from the prohibition to put other gods along with Yahweh to St. Paul's decisive word "An idol is nothing in the world," but the one was from the first involved in the other. Between "Thou shalt not make unto thee a graven image" and our Lord's declaration "God is a Spirit, and must be worshipped in spirit and in truth," there lies a long and toilsome upward movement; but the first was the gate into the path which must end in the second. Similarly, the commandment which affirmed so strongly the sacredness of the family, by hedging round the house-mother with this special defence held implicit in it all that rare and lovely purity which the best type of Christian women exhibit. The principles upon which the initial prohibitions were founded were true to fact and to the nature both of God and man. They were, therefore, never found at fault in the advancing stages of human experience; and the meaning which a modern congregation of Christians finds in these solemn "words," when they are read before them, is as truly and justly their meaning as the more meagre interpretation which alone ancient Israel could put upon them.
How gradually, and how naturally, the advancing thoughts and changed circumstances of Israel affected the Decalogue may be seen most clearly in the differences between its form as originally given, and as it is set forth in Exodus and in Deuteronomy. If the original form of these commandments was what we have indicated (p. 69), they corresponded entirely to the circumstances of the wilderness. There is no reference in them which presupposes any other social background than that of a people dwelling together according to families, possessing property, and worshipping Yahweh. None of the commandments involves a social state different from that. But when Israel had entered upon its heritage, and had become possessed of the oxen and asses which were needed in agricultural labour and in settled life, this stage of their progress was reflected in the reasons and inducements which were added to the original commands. In the fourth and tenth commandments of Exodus we have consequently the essential commandments of the earlier day adapted to a new state of things, i.e. to a settled agricultural life. Then, even as between the Exodus and Deuteronomic texts, a progress is perceptible. The reasons for keeping the Sabbath which these two recensions give are different, as we have seen, and it is probable that the reason given in Deuteronomy was first. To the people in the wilderness came the bare Divine command that this one day was to be sacred to Yahweh. In both Exodus and Deuteronomy we have additions, going into details which show that when these versions were prepared Israel had ceased to be nomadic and had become agricultural. In Deuteronomy we find that the importance and usefulness of this command from a humane point of view had been recognised, and one at least of the grounds upon which it should be held a point of morality to keep it is set forth in the words "that thy manservant and thy maidservant may rest as well as thou." Finally, if the critical views be correct, in Exodus we have the motive for the observance of the Sabbath raised to the universal and eternal, by being brought into connection with the creative activity of God.
If the progression now traced out be real, then we have in it a classical instance of the manner in which Divine commands were given and dealt with in Israel. Given in the most general form at first, they inevitably open the way for progress, and as thought and experience grow in volume and rise in quality, so does the understanding of the law as given expand. Under the influence of this expansion addition after addition is made, till the final form is reached; and the whole is then set forth as having been spoken by Yahweh and given by Moses when the command was first promulgated. In such cases literary proprietorship was never in question. Each addition was sanctioned by revelation, and those by whom it came were never thought of. It would seem, indeed, that nothing but modern sceptical views as to the reality of revelation, the feeling that all this movement to a higher faith was merely natural, and that the hand of God was not in it, could have suggested to the ancient Hebrew writers the wish to hand on the names of those by whom such changes were made. Yahweh spoke at the beginning, Moses mediated between the people and Yahweh, and the law thus mediated was in all forms equally Mosaic, and in all forms equally Divine.
One other thing remains to be noticed, and that is the prevailingly negative form of the commandments. Of the ten only the fourth and fifth are in the affirmative. All the others are prohibitions, and we who have been taught by Christianity to put emphasis upon the positive aspects of duty as the really important aspects of it, may not improbably feel chilled and repelled by a moral code which so definitely and prevailingly forbids. But the cause of this is plain. A code like that of the Twelve Tables published in early Rome is only occasionally negative, because it rises to no great height in its demands, and is intent only upon ordering the life of the citizens in their outward conduct. But this code, which seeks to raise the whole of life into the sacredness of a continual service of God and man, must forbid, because the first condition of such a life is the renunciation and the restriction of self. Benevolent dreamers and theorists of all ages, and men of the world whose moral standard is merely the attainment of the average man, have denied the evil tendency in man's nature. They have asserted that man is born good; but the facts of experience are entirely against them. Whenever a serious effort has been made to raise man to any conspicuous height of moral goodness, it has been found necessary to forbid him to follow the bent of his nature. "Thou shalt not" has been the prevailing formula; and in this sense original sin has always been witnessed to in the world. Hence the Old Testament, in which the most strenuous conflict for goodness which the world in those ages knew was being carried on, could not fail, in every part of it, to proclaim that man is not born good. However late we may be compelled to put the writing of the story of the fall as it stands in Genesis, there can be no question that it represents the view of the Old Testament at all times. Man is fallen; he is not what he ought to be, and the evil taint is handed on from one generation to another. Every generation, therefore, is called, by prophet and priest and lawgiver alike, to the conflict against the natural man.
The truth is that all along the leaders of Israel had a quite overawing sense of the moral greatness of Yahweh and of the stringency of His demands upon them. "Be ye holy, for I am holy," was His demand; and so among this people, as among no other, the sense of sin was heightened, till it embittered life to all who seriously took to heart the religion they professed. This feeling sought relief in expiatory sacrifices, like the sin offering and the guilt offering; but in vain. It then led to Pharisaic hedging of the law, to seeking a positive precept for every moment of time, to binding upon men's consciences the most minute and burdensome prescriptions, as a means of making them what they must be if they were to meet the Divine requirements. But that too failed. It became a slavery so intolerable that, when St. Paul received the power of a new life, his predominant feeling was that for the first time he knew what liberty meant. He was set free from both the bondage of sin and the bondage of ritual.
