On the Unchangeableness of God (52-54)

Now, some persons, when they hear the expressions which I have just cited, imagine that the living God is here giving away to anger and passion; but God is utterly inaccessible to any passion whatever. For it is the peculiar property of human weakness to be disquieted by any such feelings, but God has neither the irrational passions of the soul, nor are the parts and limits of the body in the least belonging to him. But, nevertheless, such things are spoken of with reference to God by the great lawgiver in an introductory sort of way, for the sake of admonishing those persons who could not be corrected otherwise.

For of all the laws which are couched in the form of injunction or prohibition, and such alone are properly speaking laws; there are two principal positions laid down with respect to the great cause of all things: one, that God is not as a man; the other, that God is as a man. [*]

But the first of these assertions is confirmed by the most certain truth, while the latter is introduced for the instruction of the many. In reference to which, it is said concerning them, "as a man would instruct his son." [*] And this is said for the sake of instruction and admonition, and not because he is really such by nature.
