The religions of the world, again, have in many cases given to many men material for life-long study. The study of the Christian Scriptures, to say nothing of Christian life and institutions, has been to many and justly famous men a study "never ending, still beginning"; not, like the world of Alexander, too limited for the powerful faculty that ranged over it; but, on the contrary, opening height on height, and with deep answering to deep, and with increase of fruit ever prescribing increase of effort. But the Reply has sounded all these depths, has found them very shallow, and is quite able to point out (p. 490) the way in which the Saviour of the world might have been a much greater teacher than He actually was; had He said anything, for instance, of the family relation, had He spoken against slavery and tyranny, had He issued a sort of _code Napoleon_ embracing education, progress, scientific truth, and international law. This observation on the family relation seems to me beyond even the usual measure of extravagance when we bear in mind that, according to the Christian scheme, the Lord of heaven and earth "was subject" (St. Luke ii. 51) to a human mother and a reputed human father, and that He taught (according to the widest and, I believe, the best opinion) the absolute indissolubility of marriage. I might cite many other instances in reply. But the broader and the true answer to the objection is, that the Gospel was promulgated to teach principles and not a code; that it included the foundation of a society in which those principles were to be conserved, developed, and applied; and that down to this day there is not a moral question of all those which the Reply does or does not enumerate, nor is there a question of duty arising in the course of life for any of us, that is not determinable in all its essentials by applying to it as a touchstone the principles declared in the Gospel. Is not, then, the _hiatus_, which the Reply has discovered in the teaching of our Lord, an imaginary _hiatus_? Nay, are the suggested improvements of that teaching really gross deteriorations? Where would have been the wisdom of delivering to an uninstructed population of a particular age a codified religion, which was to serve for all nations, all ages, all states of civilization? Why was not room to be left for the career of human thought in finding out, and in working out, the adaptation of Christianity to the ever varying movement of the world? And how is it that they who will not admit that a revelation is in place when it has in view the great and necessary work of conflict against sin, are so free in recommending enlargements of that Revelation for purposes, as to which no such necessity can be pleaded?
