About two centuries after the formation of the first World State, the President of the World declared that the time was ripe for a formal union of science and religion, and called a conference of the leaders of these two great disciplines. Upon that island in the Pacific which had become the Mecca of cosmopolitan sentiment, and was by now one vast many-storied, and cloud-capped Temple of Peace, the heads of Buddhism, Mohammedanism, Hinduism, the Regenerate Christian Brotherhood and the Modern Catholic Church in South America, agreed that their differences were but differences of expression. One and all were worshippers of the Divine Energy, whether expressed in activity, or in tense stillness. One and all recognized the saintly Discoverer as either the last and greatest of the prophets or an actual incarnation of divine Movement. And these two concepts were easily shown, in the light of modern science, to be identical.
