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
