Names were then definitions, and Moses asked God to define himself so that he might be comprehensible. This God refused to do. Who Is, the Eternal One. John Calvin stressed the primacy of God's self-revelation and man's assent to it, and this gave to consistent Calvinists an unrivaled strength. To stand on the sovereignty of God and of his revelation is to stand on more than one's rationalizations.
Rationalization always misdefines man.
For Aristotle, man was a political animal. All non-Biblical definitions of God reduce man to a creature of natural forces, to another kind of animal, to cite Aristotle. Only in his reason does he to some degree rise above himself. Other men were as cattle and sheep, to be herded into the way they should go. In the Platonic tradition, reason is a tool for domination, to be used by the philosopher-kings to control mankind.
