That man is a social being is the fundamental fact with which all social sciences have to deal. We may like or dislike people; we can not well be indifferent to them if they get close to us. As Sartor Resartus puts it: “In vain thou deniest it; thou _art_ my brother. Thy very hatred, thy very envy, those foolish lies thou tellest of me in thy splenetic humour; what is all this but an inverted sympathy? Were I a steam-engine, wouldst thou take the trouble to tell lies of me?” Sex admiration, parental love, “the dear love of comrades,” the thrill of patriotism, the joy of play, are all forms of fellowship. They give us happiness because they satisfy our social instinct. To realize our unity gives relish to life. To be thrust out of fellowship is the great pain. Many evil things get their attractiveness mainly through the fact that they create a bit of fellowship—such as it is. The slender thread of good in the saloon is comradeship. (See Jack London, “John Barleycorn.”) I None ever felt this social unity of our race more deeply than Jesus. To him it was sacred and divine. Hence his emphasis on love and forgiveness. He put his personality behind the natural instinct of social attraction and encouraged it. He swung the great force of religion around to bear on it and drive it home. Anything that substitutes antagonism for fraternity is evil to him. Just as in the case of the natural respect for human life and personality, so in the case of the natural social cohesion of men, he lifted the blind instinct of human nature by the insight of religion and constituted it a fundamental principle of life. It is the business of Christianity to widen the area of comradeship. Common human judgment assents to the valuation of Jesus. Wherever an effective and stable form of fellowship has been created, a sense of sacredness begins to attach to it, and men defend it as a sort of shrine of the divine in man. Wherever men are striving to create a larger fellowship, they have religious enthusiasm as if they were building a temple for God. This is the heart of church loyalty.
