In order to choose between different gods, and different forms of faith, a man must possess the faculty of choosing the instruments of testing truth and untruth, whether revealed or not; he must know that certain fundamental tenets cannot be absent in any true religion, and that there are doctrines against which his rational or moral conscience revolts as incompatible with truth. In short, there must be the foundation of religion, there must be the solid rock, before it is possible to erect an altar, a temple, or a church: and if we call that foundation natural religion, it is clear that no revealed religion can be thought of which does not rest more or less firmly on natural religion. _Science of Religion._ Universal primeval revelation is only another name for natural religion, and it rests on no authority but the speculations of philosophers. The same class of philosophers, considering that language was too wonderful an achievement for the human mind, insisted on the necessity of admitting a universal primeval language, revealed directly by God to men, or rather to mute beings: while the more thoughtful and more reverent of the Fathers of the Church, and among the founders of modern philosophy also, pointed out that it was more consonant with the general working of an all-wise and all-powerful Creator that He should have endowed human nature with the essential conditions of speech, instead of presenting mute beings with grammars and dictionaries ready-made. The same applies to religion. A universal primeval religion revealed direct by God to man, or rather to a crowd of atheists, may, to our human wisdom, seem the best solution of all difficulties; but a higher wisdom speaks to us out of the realities of history, and teaches us, if we will but learn, that 'we have all to seek the Lord, if haply we may feel after Him, and find Him, though He is not far from every one of us.' _Science of Religion._ The study of the ancient religions of mankind, I feel convinced, if carried on in a bold, but scholarlike, careful, and reverent spirit, will remove many doubts and difficulties which are due entirely to the narrowness of our religious horizon; it will enlarge our sympathies, it will raise our thoughts above the small controversies of the day, and at no distant future evoke in the very heart of Christianity a fresh spirit and a new life. _Science of Religion._
