These words contain the germ of St. Paul’s doctrine that the law itself was a schoolmaster, and its function temporary.
To whatever concessions Moses had been driven, the original and unshaken design of God was that man and woman should find the permanent completion of their lives each in the other. And this is shown by three separate considerations. The first is the plan of the creation, making them male and female, and such that body and soul alike are only perfect when to each its complement is added, when the masculine element and the feminine “each fulfils defect in each ... the two-celled heart beating with one full stroke life.” Thus by anticipation Jesus condemned the tame-spirited verdict of His disciples, that since a man cannot relieve himself from a union when it proves galling, “it is not good” to marry at all. To this he distinctly answered that such an inference could not prove even tolerable, except when nature itself, or else some social wrong, or else absorbing devotion to the cause of God, virtually cancelled the original design. But already he had here shown that such prudential calculation degrades man, leaves him incomplete, traverses the design of God Who from the beginning of the creation made them male and female. In our own days, the relation between the sexes is undergoing a social and legislative revolution. Now Christ says not a word against the equal rights of the sexes, and in more than one passage St. Paul goes near to assert it. But equality is not identity, either of vocation or capacity. This text asserts the separate and reciprocal vocation of each, and it is worthy of consideration, how far the special vocation of womanhood is consistent with loud assertion of her “separate rights.”
Christ’s second proof that marriage cannot be dissolved without sin is that glow of heart, that noble abandonment, in which a man leaves even father and mother for the joy of his youth and the love of his espousals. In that sacred hour, how hideous and base a wanton divorce would be felt to be. Now man is not free to live by the mean, calculating, selfish afterthought, which breathes like a frost on the bloom of his noblest impulses and aspirations. He should guide himself by the light of his highest and most generous intuitions.
And the third reason is that no man, by any possibility, can undo what marriage does. They two are one flesh; each has become part of the very existence of the other; and it is simply incredible that a union so profound, so interwoven with the very tissue of their being, should lie at the mercy of the caprice or the calculations of one or other, or of both. Such a union arises from the profoundest depths of the nature God created, not from mean cravings of that nature in its degradation; and like waters springing up from the granite underneath the soil, it may suffer stain, but it is in itself free from the contamination of the fall. Despite of monkish and of Manichean slanders, impure dreams pretending to especial purity, God is He Who joins together man and woman in a bond which “no man,” king or prelate, may without guilt dissolve.
Of what followed, St. Mark is content to tell us that in the house, the disciples pressed the question further. How far did the relaxation which Moses granted over-rule the original design? To what extent was every individual bound in actual life? And the answer, given by Jesus to guide His own people through all time, is clear and unmistakeable. The tie cannot be torn asunder without sin. The first marriage holds, until actual adultery poisons the pure life in it, and man or woman who breaks through its barriers commits adultery. The Baptist’s judgment of Herod was confirmed.
So Jesus taught. Ponder well that honest unshrinking grasp of solid detail, which did not overlook the physical union whereof is one flesh, that sympathy with high and chivalrous devotion forsaking all else for its beloved one, that still more spiritual penetration which discerned a Divine purpose and a destiny in the correlation of masculine and feminine gifts, of strength and grace, of energy and gentleness, of courage and long-suffering—observe with how easy and yet firm a grasp He combines all these into one overmastering argument—remember that when He spoke, the marriage tie was being relaxed all over the ancient world, even as godless legislation is to-day relaxing it—reflect that with such relaxation came inevitably a blight upon the family, resulting in degeneracy and ruin for the nation, while every race which learned the lesson of Jesus grew strong and pure and happy—and then say whether this was only a Judæan peasant, or the Light of the World indeed.
