When we turn to modern times and modern circumstances, it is not easy to see how this ancient law can be applicable to them. In the first place, much of it was made binding upon Israel only because of its peculiar character as the people to whom the true religion was revealed. As custodians of that, they were justified in keeping up walls of partition between themselves and the world, which if universally accepted would only be hurtful to the highest interests of mankind. On the contrary, the development of the true religion having been completed by the coming of Christ, it is the duty of those nations which enjoy the light to spread abroad the "good news" of God which they have received, and to exhibit its power among all the nations of the earth. The highest and most Divine call which can now come to any people must, therefore, be radically different in some chief aspects from that of Israel. In the second place, the civilisation and culture of the great nations of to-day are far more complicated than any ancient civilisation ever was, and the general level is fixed by an action and reaction extending over the whole civilised world. No successes can be achieved, no blunders can be committed, in any part of the world which do not affect almost immediately the farthest ends of the earth. Moreover the intimate and universal correlation of interest makes interference with any part of the complicated whole an exceedingly perilous matter. Any proposal that this law, as being Divinely given, ought in its economic aspect to be made universally binding, should therefore be met by a demand for a careful inquiry into possible differences between ancient life and modern, which might make guidance Divinely given to the one inapplicable to the other. It is not necessarily true that because Israel by Divine command established every household upon the soil, forbade interest, and did nothing to encourage trade and manufactures, we should do these things. Take, for instance, the case of interest. In our day, and in civilisations of a high type, lending money to a person not in distress at all, but who sees an opportunity of making-enough by the use of borrowed money to pay the interest and make a profit, is often a most praiseworthy and charitable act.
But if the Israelite legislation in regard to interest cannot justly be taken as a law for all time, still less can any great modern state neglect or discourage commerce and manufactures. The merely embryonic character of commercial legislation, and the contempt for the merchant which did in ancient days exist, would be exceedingly out of place now. There is no career more honourable than that of the merchant of our day when he carries on his business in a high-minded fashion, nor is there any member of the community whose calling is more beneficent than his. So long as he looks for gain to himself in ways which, taken on the great scale, bring benefit both to producer and consumer, his activity is purely beneficial. There is absolutely no reason why commercial life should not be as honest, as sound, as much in accord with the mind of God, in itself, as any other manner of life. For in many ways it has been a civilising agent of the highest power. Of course, if the charges brought against merchants by Ruskin, for example, who seizes upon and believes every story which involves charges of fraud against modern commerce, were true; if it were impossible, as he says it is, for an honest man to prosper in trade, then we might have some ground for condemning this branch of human activity. But happily only a confirmed and incorrigible pessimist can believe that. In our time some of the noblest men of whom we have any knowledge have been merchants, and among no class has so much princely generosity been exhibited. If mercantile help had been withdrawn from the poor, if the time, the money, the organising skill which merchants have freely expended upon charities were suddenly to fail them, the case against our modern civilisation would be indefinitely stronger than it is. Moreover the immense expansion of credit which is at once the glory and the danger of modern commerce, is itself a proof that such wholesale condemnation as we have spoken of is unwarrantable. The bulk of commerce must, after all, be fairly sound, otherwise it could not continue and spread as it does. And, as against the evils which affect it in common with all human activities, we must put the fact that it brings the produce of all lands to the door even of the poor, and by the constant contact between nations which it causes it is influencing the thought as well as the lives of men. Human brotherhood is being furthered by it, slowly, it is true, but surely, and the barriers which separate the nations are being sapped by its influence. These are indispensable services for the future progress of mankind, and make commerce now as much the necessary handmaid of the highest life as it would have been a hindrance to it in the case of the chosen people, before they had assimilated the truths of which they were to be the bearers to the world. That commerce, and trade in general, need to be purified goes without saying. That it may, of late years, have deteriorated, as the general decay of faith and the pursuit of luxury have weakened the sanctions of morality, is not improbable. But in itself it is not only a legitimate human activity; it is also an admirable instrument for bringing home to the consciences of men the truth that they are all their brothers' keepers. It presses home as nothing else could do the great truth proclaimed by St. Paul in regard to the Church, as true also of the world, that if one member suffers all the body suffers with it. Every day through this channel men are receiving lessons, which they cannot choose but hear, to the effect that no permanent benefit can come from the loss and suffering of men in any part of the world; that peace and righteousness and good faith are things which have supreme value even in the mercantile sense; and that, conversely, the merchant's pursuit of wealth, if carried on in accord with the fundamental truths of morality, inevitably becomes a potent factor in that advance to a worldwide knowledge of the Lord, which gleamed before the eyes of prophets and seers as the
