That the Decalogue in any of its forms must have been the work of one mind, and that a very great and powerful mind, will be evident on the most cursory inspection. We have not here, as we have in other parts of Scripture, fragments of legislation supplementary to a large body of customary law, fragments which, because of their intrinsic importance or the necessities of a particular time, have been written down. We have here an extraordinarily successful attempt to bring within a definite small compass the fundamental laws of social and individual life. The wonder of it does not lie in the individual precepts. All of them, or almost all of them, can be paralleled in the legislation of other peoples, as indeed could not fail to be the case if the _fundamental_ laws of society and of individual conduct were aimed at. These must be obeyed, more or less, in every society that survives. It is the wisdom with which the selection has been made; it is the sureness of hand which has picked out just those things which were central, and has laid aside as irrelevant everything local, temporary, and purely ceremonial; it is the relation in which the whole is placed to God,--these give this small code its distinction. In these respects it is like the Lord's Prayer. It is vain for men to point out this petition of that unique prayer as occurring here, that other as occurring there, and a third as found in yet another place. Even if every single petition contained in it could be unearthed somewhere, it would still remain as unique as ever; for where can you find a prayer which, like it, groups the fundamental cries of humanity to God in such short space and with so sure a touch, and brings them all into such deep connection with the Fatherhood of God? In both cases, in the prayer and in the Decalogue alike, we must recognise that the grouping is the work of one mind; and in both we must recognise also that, whatever were the natural and human powers of the mind that wrought the code and prayer respectively, the main element in the success that has attended their work is the extraordinary degree in which they were illumined by the Divine Spirit. But where, between the time of Moses and the time when Deuteronomy first laid hold upon the life of the nation, are we to look for a legislator of this pre-eminence? So far as we know the history, there is no name that would occur to us. So far as can be seen, Moses alone has been marked out for us in the history of his people as equal to, and likely to undertake, such a task. Everything, therefore, concurs to the conclusion that in the Decalogue we have the first, the most sacred, and the fundamental law in Israel. Here Moses spoke for God; and whatever additions to his original ten words later times may have made, they have not obscured or overlaid what must be ascribed to him. He may not have been the author of much that bears his name, for unquestionably there were developments later than his time which were called Mosaic because they were a continuation and adaptation of his work; but we are justified in believing that here we have the first law he gave to Israel; and in it we should be able to see the really germinal principles of the religion he taught.
Now, manifestly, a religion which spoke its first word in the ten commandments, even in their simplest form, must have been in its very heart and core moral. It must always have been a heresy therefore, a denial of the fundamental Mosaic conception, to place ritual observance _per se_ above moral and religious conduct, as a means of approach to Yahweh. On any reading of the commandments only the third and fourth (two out of ten) refer to matters of mere worship; and even these may more correctly be taken to refer primarily to the moral aspects of the cultus. All the rest deal with fundamental relations to God and man. Consequently the prophets who, after the manner of Amos and Hosea, denounce the prevailing belief that Yahweh's help could be secured for Israel, whatever its moral state, by offerings and sacrifices, were not teaching a new doctrine, first discovered by themselves. They were simply reasserting the fundamental principles of the Mosaic religion. Reverence and righteousness--these from the first were the twin pillars upon which it rested. Before ever the ceremonial law, even in its most rudimentary form, had been given, these were emphasised in the strongest way as the requirements of Yahweh; and the people whom the prophets reproved, instead of being the representatives of the ancient Yahwistic faith, had rejected it. Whether the popular view was a falling away from a truer view which had once been popular, or whether it represented a heathen tendency which remained in Israel from pre-Mosaic times and had not even in the days of Amos been overcome, it seems undeniable that it was entirely contrary to the fundamental principles of Yahwism as given by Moses. Even by the latest narrators, those who brought our Pentateuch into its present shape, and who were, it is supposed, completely under the influence of ceremonial Judaism, the primarily moral character of Yahweh's religion was acknowledged by the place they gave to the ten commandments. They alone are handed down as spoken by Yahweh Himself, and as having preceded all other commands; and the terrors of Sinai, the thunder and the earthquake, are made more intimately the accompaniments of this law than of any other. Unquestionably the mind of Israel always was, that here, and not in the ceremonial law, was the centre of gravity of Yahwism. In the view of that fact it is somewhat hard to understand how so many writers of our times, who admit the Decalogue to have been Mosaic, or at any rate pre-prophetic, yet deny the prevailingly moral character of the early religion of Israel. When this law was once promulgated, the old naturalism in which Israel, like other ancient races, had been entangled was repudiated, and the relation between Yahweh and His people was declared to be one which rested upon moral conduct in the widest sense of that term. And the ground of this fact is plainly declared here to be the character of Yahweh: "I am the Lord thy God, that brought thee out of the land of Egypt, out of the house of bondage." He was their deliverer, He had a right to command them, and His commands revealed His nature to His people.
