Thus the God of Judaism, the world's great _I Am_, forms a complete contrast, not only to the lifeless powers of nature and destiny, which were worshiped by the ancient pagans, but also to the God of modern paganism, a God divested of all personality and self-consciousness, such as He is conceived of by the new school of Christian theology, with its pantheistic tendency. I refer to the school of Ritschl, which strives to render the myth of the man-god philosophically intelligible by teaching that God reaches self-consciousness only in the perfect type of man, that is, Christ, while otherwise He is entirely immanent, one with the world. All the more forcibly does Jewish monotheism insist upon its doctrine that God, in His continual self-revelation, is the supermundane and self-conscious Ruler of both nature and history. "I am the Lord, that is My name, and My glory will I not give to another,"--so says the God of Judaism.(178)
4. The Jewish God-idea, of course, had to go through many stages of development before it reached the concept of a transcendental and spiritual god. It was necessary first that the Decalogue and the Book of the Covenant prohibit most stringently polytheism and every form of idolatry, and second that a strictly imageless worship impress the people with the idea that Israel's God was both invisible and incorporeal.(179) Yet a wide step still intervened from that stage to the complete recognition of God as a purely spiritual Being, lacking all qualities perceptible to the senses, and not resembling man in either his inner or his outer nature. Centuries of gradual ripening of thought were still necessary for the growth of this conception. This was rendered still more difficult by the Scriptural references to God in His actions and His revelations, and even in His motives, after a human pattern. Israel's sages required centuries of effort to remove all anthropomorphic and anthropopathic notions of God, and thus to elevate Him to the highest realm of spirituality.(180)
5. In this process of development two points of view demand consideration. We must not overlook the fact that the perfectly clear distinction which we make between the sensory and the spiritual does not appeal to the child-like mind, which sees it rather as external. What we call transcendent, owing to our comprehension of the immeasurable universe, was formerly conceived only as far remote in space or time. Thus God is spoken of in Scripture as dwelling in heaven and looking down upon the inhabitants of the earth to judge them and to guide them.(181) According to Deuteronomy, God spoke from heaven to the people about Mt. Sinai, while Exodus represents Him as coming down to the mountain from His heavenly heights to proclaim the law amid thunder and lightning.(182) The Babylonian conception of heaven prevailed throughout the Middle Ages and influenced both the mystic lore about the heavenly throne and the philosophic cosmology of the Aristotelians, such as Maimonides. Yet Scripture offers also another view, the concept of God as the One enthroned on high, whom "the heavens and the heaven's heavens cannot encompass."(183)
