"While the religions of the world have a double origin—natural and revelatory—at any one time and among any one people there are to be found three distinct forms of religious devotion. And these three manifestations of the religious urge are: "1. Primitive religion. The seminatural and instinctive urge to fear mysterious energies and worship superior forces, chiefly a religion of the physical nature, the religion of fear. "2. The religion of civilization. The advancing religious concepts and practices of the civilizing races—the religion of the mind—the intellectual theology of the authority of established religious tradition. "3. True religion—the religion of revelation. The revelation of supernatural values, a partial insight into eternal realities, a glimpse of the goodness and beauty of the infinite character of the Father in heaven—the religion of the spirit as demonstrated in human experience.
