A third class which the Church needs to-day is that of the working-man. The hand of the working-man is the hand that has really moulded history. Working-men lead a brave and self-sacrificing life. From their toil come the necessaries and many of the comforts of the race. The man of labor knows the root-problems of the industrial world. While all his industry and skill, all his courage, heroism, and strong-armed life are so largely alienated from the Church, the Church is deprived of one of the fundamental sources of inspiration and growth. The tree of progress can never grow, except it has labor-roots. It is absolutely essential for the health of the Church that every form of human energy be represented. Suppose that by some great revival a very large number of working men and women could suddenly be added to the membership of the Church. What would happen? Would there not be at once a return to more simplicity of life? There are two currents at work always in society--emulation and sympathy. Rightly used, each is for the social good. If all classes of men and women worked side by side in the Church, many great social differences would become adjusted. 5. It holds sway over the fortunes of the home. Where, outside of the Church, will you find the ideal conception of marriage, and the really united and happy home? The Church makes for domestic happiness, because it goes straight to the roots of life and plants happiness where happiness alone can grow. More and more the Church is lifting the standards of a noble, proud, pure, and rejoicing married life. Its ideal of human love is sacred, because founded on the deeper love of the soul in God. The Church is drawing hosts of young people under the shelter of its teaching, and is placing before men and women ideals which cannot fail to make their mark upon the social standards of the times. It stands for purity, for patience, for tenderness, for the love of little children, for united education and endeavor, for mutual hopes and dreams, for large public service. 6. It is the militant force of time. We speak of the Church militant, and of the Church triumphant. For us, to-day, the Church militant. To-morrow, triumph comes. Armies have been, and armies shall be, but the hosts of this world fight against material foes, and largely for material ends. It is the glory of the Church militant that its conquests are spiritual and its victories are eternal. Its fight is chiefly against the inner, not the outer foe--against sin and wrong-doing, impatience, strife, anger, clamor, meanness, evil-speaking, wrath. It is the foe of tyranny and its heel is upon the head of the oppressor and the avenger. Its banner flies over every country and has been carried through tribulation, through sorrow, through danger, and through death to the remotest parts of the yet-known world. Its troops are legion, marching from the far distances of the past, and extending out to the far confines of the eternal years.
