It may appear a strange thing that the precept, "Ye shall be holy; for I am holy," was affixed not only to moral duties but with almost the same force to ceremonial duties. We can understand this, however, when we trace the result of the priestly ordinances. They created religious care and feeling; and the end was gained not so much by directing attention, as we now do, to faults of conduct, defects of will, sins of injustice, impurity, intemperance, and the like, but by keeping up a scrupulous attention to matters not, properly speaking, either moral or immoral, not ethical as we say, which were yet declared to be of moment in religion. The moral law did its part. But to make the enforcement of moral statutes, many of which bore on desire and will, the only means of urging the fear of God, would have resulted practically in a very bare and desultory cultus. Among a comparatively rude people like the Israelites it would have been absurd to institute a religion consisting of "morality touched by emotion." For the mass of people still it is equally hopeless. There must be ordinances of prayer, praise, sacrament, and the duties which reach Godward through the Church. The value of the whole ceremonial system of the Mosaic law is clear from this point of view; and we need not wonder in the least at the nature of many provisions which, without grasp of the principle, we might reckon irksome and useless. The origin of some of the statutes is apparently hygienic; others again reach back to customs and beliefs of a very primitive world. But they are made part of the sacred law in order to enforce the conviction that the judgment of God enters into the whole of life, follows men wherever they go, decides as to their state with relation to Him hour by hour, almost moment by moment. The ceremonial law was a constant and strenuous lesson in regard to the omnipresence of God, and the oversight of human affairs by Him. It created a conscience of God's existence, His control, His superintendence of each life. And for a certain stage of the education of Israel this could be achieved in no other way. The moral and spiritual progress of a people, depending on the recognition of the authority of One who is of purer eyes than to behold iniquity, depends also, of necessity, on the sense of His oversight of human life at every point. 1.
