The contributions made by Christianity to the working efficiency and the constructive social abilities of humanity in the past have been mainly indirect. The main aim set before Christians was to save their souls from eternal woe, to have communion with God now and hereafter, and to live God-fearing lives. It was individualistic religion, concentrated on the life to come. Its social effectiveness was largely a by-product. What, now, would have been the result if Christianity had placed an equally strong emphasis on the Kingdom of God, the ideal social order? Other things being equal, a Christian father and mother are better parents than others because they have more sense of duty, more love, and a higher valuation of spiritual things. But if, in addition, they have a religious desire for a higher social order and realize that noble children are a splendid contribution to it, how will that affect their parenthood? A teacher, artist, or scientist who is also a religious man, will do conscientious work if he works under the motives of individualistic religion. But if he has a vision of the Kingdom of God on earth and sees the contributions he can make to it, will not that raise the character of his output? A business man of strong Christian character will work hard, keep his word in business, and deal fairly with employes and customers. But would not a new direction be given to his moral energies if his religion taught him that he must help to shape the workings of industry and trade so that hereafter there will be no fundamental clash between business and the morals of Christianity? What the world of Christian men and women needs is to have a great social objective set before them and laid on their conscience with the authority of religion. Then religion would get behind social evolution in earnest. This would be no new and foreign element imported into our religion. It would be a modern revival of the doctrine of Jesus himself, which has been too long submerged and neglected. One chief reason why it was side-tracked is that no despotic State and no society dominated by a predatory class ever wanted religion applied to a reconstruction of the social order. The idea of the Kingdom of God reawoke with the rise of modern democracy. Now is the time for it. III The idea of the Kingdom of God is not identified with any special social theory. It means justice, freedom, fraternity, labor, joy. Let each social system and movement show us what it can contribute and we will weigh its claims. We want the old ideal defined in modern terms, in the terms of modern democracy, of the power machine, of international peace, and of evolutionary science. But we want to embrace it with the old religious faith and ardor, so that we can pray over it.
