The God of the Hebrew Bible is for the most part an anthropomorphic and anthropopathic being, that is, a God who has the form and emotions of humans. He (it is a he) walks and talks, has arms and legs, becomes angry, happy, or sad, changes his mind, speaks to humans and is addressed by them, and closely supervises the affairs of the world. The God of the philosophers is a different sort of being altogether: abstract (the Prime Mover, the First Cause, the Mind or Soul of the Universe, etc.), immutable, and relatively unconcerned with the affairs of humanity. The tension between these rival conceptions of the Deity is evident in the work of Philo, who is able lo find a philosophically respectable God in the Torah only through allegorical exegesis. Philo is particularly careful to sanitize the anthropomorphic and anthropopathic passages. In the land of Israel the pressure to interpret the Bible in this fashion was less intense, but even here many of the Targumim, the Aramaic translations of scripture, reduce or eliminate the scriptural anthropomorphisms.
Perhaps some Jews were concerned about the very unphilosophical image of God in the Hebrew scriptures, but most Jews were not. Apocalyptic visionaries and mystics persisted in seeing God sitting on his throne surrounded by his angelic attendants. The rabbis had no difficulty in believing in a God who loves and is loved and with whom one can argue. The masses needed (and need!) a God who is accessible and understandable. In the fourth century most of the monks in Egypt understood the anthropomorphisms of scripture literally. After all, God declares, "Let us make man in our image" (Gen. 1:26), proof that the image of man is the image of God. After hearing a pastoral letter from the bishop of Alexandria and a sermon from his abbot which insisted that the scriptural anthropomorphisms were to be understood allegorically because God has no shape, one elderly monk arose to pray but could not. "Woe is me! They have taken my God away from me!" he wailed. Popular piety does not need or want an immutable and shapeless Prime Mover; it wants a God who reveals himself to people, listens to prayer, and can be grasped in human terms. This is the God of the Shema, the Bible, and the liturgy. This is the God of practically all the Hebrew and Aramaic, and some of the Greek, Jewish literature of antiquity. It is not, however, the God of the philosophers.
