The conceptions of God are various, differing widely in different systems of religion and metaphysics; but they fall, in general, under two heads: theism, which is most fully developed in Christianity, and in which God is regarded as a personal moral being, distinct from the universe, of which he is the author and ruler; and pantheism, in which God is conceived as not personal, and as identified with the universe. See theism, pantheism.
