In both Biblical and rabbinical literature the angels are usually conceived of as purely spiritual powers superior to man. Maimonides, however, following his rationalistic method, declared them to be simply products of the imagination, the hypostases of figurative expressions which were not meant to be taken literally. To him every force and element of nature is an angel or messenger of God. In this way the entire angelology of the Bible, including even Ezekiel's vision of the heavenly chariot (the _Merkabah_), in becoming a part of the Maimonidean system turns into natural philosophy pure and simple.(553) Of course, Saadia, Jehuda ha Levi, and Gabirol do not share this rationalistic view. To them the angels are either cosmic powers of an ethereal substance, endowed with everlasting life, or living beings created by God for special purposes.(554)
The later Cabbalistic lore extended the realm of the celestial spirits still more, creating new names of angels for its mystical system and its magical practices. Yet in this magic it subordinated the angels to man. In fact, it followed Saadia largely in this, making man the center and pinnacle of the work of creation, in fact, the very mirror of the Creator.(555)
8. For our modern viewpoint the existence of angels is a question of psychology rather than of theology. The old Babylonian world has vanished, with its heaven as the dwelling place of God, its earth for man, and its nether world for the shades and demons. The world in which we live knows no above or beneath, no heaven or hell, no host of good and evil spirits moving about to help or hurt man. It sees matter and energy working everywhere after the same immutable laws through an infinitude of space and time, a universe ever evolving new orbs of light, engendering and transforming worlds without number and without end. There is no place in infinite space for a heaven or for a celestial throne. A world of law and of process does not need a living ladder to lead from the earth below to God on high. Though the stars be peopled with souls superior to ours, still they cannot stand nearer to God than does man with his freedom, his moral striving, his visions of the highest and the best. Through man's spiritual nature God, too, is recognized as a Spirit; through man's moral consciousness God is conceived of as the Ruler of a moral world; but this same process at once does away with the need for any other spirits or divine powers beside Him. God alone has become the object of human longing. Man feels akin to His God who is ever near; he learns to know Him ever better. He can dispense with the angelic hosts. As they return to the fiery stream of poetic imagination whence they emerged, nebulous figures of a glorious world that has vanished, man rises above angel and Seraph by his own power to the dignity of a servant, nay, a child of God. Indeed, as the rabbis said, the prophets, sages, and seers are the true messengers of God, the angels who do His service.(556)
