Such is a brief summary of the law of the clean and the unclean as contained in this chapter. To preclude adding needless difficulty to a difficult subject, the remark made above should be specially noted,--that so far as general marks are given by which the clean is to be distinguished from the unclean, these marks are evidently selected simply from a practical point of view, as of easy recognition by the common people, for whom a more exact and scientific mode of distinction would have been useless. We are not therefore for a moment to think of cleanness or uncleanness as causally determined, for instance, by the presence or absence of fins or scales, or by the habit of chewing the cud, and the dividing of the hoof, or the absence of these marks, as if they were themselves the ground of the cleanness or uncleanness, in any instance. For such a fancy as this, which has diverted some interpreters from the right line of investigation of the subject, there is no warrant whatever in the words of the law, either here or elsewhere. Than this law concerning things clean and unclean nothing will seem to many, at first, more alien to modern thought, or more inconsistent with any intelligent view of the world and of man's relation to the things by which he is surrounded. And, especially, that the strict observance of this law should be connected with religion, and that, upon what professes to be the authority of God, it should be urged on Israel on the ground of their call to be a holy people to a holy God,--this, to the great majority of Bible readers, certainly appears, to say the least, most extraordinary and unaccountable. And yet the law is here, and its observance is enforced by this very consideration; for we read (vv. 43, 44): "Ye shall not make yourselves abominable with any creeping thing that creepeth, neither shall ye make yourselves unclean with them, that ye should be defiled thereby. For I am the Lord your God: sanctify yourselves therefore, and be ye holy; for I am holy." And, in any case, explain the matter as we may, many will ask, How, since the New Testament formally declares this law concerning clean and unclean beasts to be no longer binding (Col. ii. 16, 20-23), is it possible to imagine that there should now remain anything in this most perplexing law which should be of spiritual profit still to a New Testament believer? To the consideration of these questions, which so naturally arise, we now address ourselves.
