The history of religions, of which Christianity is a transcendent element, awaits the deepest study. It requires Bibles to free from Bibles. Comparative theology is the best of studies for liberating one's mind from geographical and traditional limitations. Like travelling, it shows the globe in its varying climates and zones, its latitude and longitude of intelligence. When the races shall have learned each other's language, the significance of things to thoughts, one faith becomes universal, one brotherhood.
