The coming religion must also be humane and social. Intellectual it must certainly be, but it must, too, be emotional and adoring. There are three implications in it--a spiritual nature in man, a living power in the universe, an eternal life of progress and attainment, and these are assured only by reason. The coming religion, we may add, must be Christian in name, because Christianity as an ideal faith has worked itself into our common life. It is the soul of our laws, of our customs, of our institutions. All assume its authority; all respect its sanction. The great thinkers of the world conspire in thinking so. Thus Goethe says: Let intellectual culture progress; let natural science extend our knowledge; let the human mind grow; it will never outstrip the grandeur of Christianity, nor its moral culture. Strauss, in his essay on "The Transient and Permanent in Christianity," declares that humanity never will be without religion; and Laveleye says: It is Christianity which has shed abroad in the world the idea of fellowship, from which issue the aspirations after equality which threaten the actual social order; it is also the influence of Christianity which arrests the explosion of this subversive force, and its principles, better comprised and better applied, will bring back by degrees peace in society. Ours is a scientific age. There is a general demand for knowledge, a desire for demonstrated truth. Many will believe nothing that they cannot see with their eyes. In this sense, and in this sense alone, it is true that facts count for nothing in the domain of religion. But there are facts of the inner world that are quite as important as any facts in the outer world,--facts of the imagination; facts of love; facts of faith. Nothing is truer than that we are saved by hope. Science has enlarged the world; has beautified it; has made it look orderly, harmonious, poetic; but the realm of the known is very small indeed as compared with the realm of the unknown, and the more we discover, the more we find that there is to discover. The realm of the inner world is immensely large; and thousands of years must elapse before we discover its contents, if we ever do. The language of James Martineau is as true to-day as it was when the words were spoken, more than fifty years ago:
