The Persian prophet, Zoroaster, recruited soldiers of the god of light among the best men to fight against the god of darkness. His religious institution was like a military barracks. The Christian Church included both the best and the worst, the righteous and the sinners, the healthy and the sick. It was a barracks and a hospital at the same time. It was an institution both for spiritual fighting and spiritual healing. The Chinese sage, Confucius, preached a wonderful ethical pragmatism, and the profound thinker, Lao-Tse, preached an all-embracing spiritualism. Christian wisdom included both of them, opening Heaven for the first and showing the dramatic importance of the physical world for the second. Islam--yes, Islam had in some sense a Christian ambition: to win the whole world. The difference was: Islam wished world-conquest; the Church, the world's salvation. Islam intended to subdue all men and bring them before God as His servants: The Church intended to educate all men, to purify and elevate them, and to bring them before God as His children. And all others: star-worshippers, and fire, and wood, and water, and stone, and animal-worshippers had a touching sense of the immediate divine presence in nature. The Church came not to extinguish this sense but to explain and to subordinate it; to put God in the place of demons and hope instead of fear. The Church came not to destroy, but to purify, to aid and to assimilate. The destination of the Church was neither national nor racial, but cosmic. No exclusive power was ever destined to be a world-power. The ultimate failure of Islam to become a world-power lies in its exclusiveness. It was with religion as with politics. Every exclusive policy is foredoomed to failure: the German as well as the Turkish and the Napoleonic. The policy of the Church was designed by her Divine Founder: "He that is not against us is for us." Well, there is no human race on earth wholly against Christ and wholly unprepared to receive Him. The wisdom of the Christian missionaries therefore is to see first in what ways Providence has prepared a soil for Christian seed; to see which of the Christian elements a race, or a religion, already possesses, and how to utilise these elements and weld them into Christianity. All that--in order to make Christianity grow organically, instead of pushing it mechanically.
