BOOK TWELFTH.

would smile at these argumentations, with which the godless endeavour to turn our simple piety from the right way, that we may walk with them "in a circle." But by the help of the Lord our God, even reason, and that readily enough, shatters these revolving circles which conjecture frames. For that which specially leads these men astray to prefer their own circles to the straight path of truth, is, that they measure by their own human, changeable, and narrow intellect the divine mind, which is absolutely unchangeable, infinitely capacious, and, without succession of thought, counting all things without number. So that saying of the apostle comes true of them, for, "comparing themselves with themselves, they do not understand."⁵¹¹ For because they do, in virtue of a new purpose, whatever new thing has occurred to them to be done (their minds being changeable), they conclude it is so with God; and thus compare, not God,—for they cannot conceive God, but think of one like themselves when they think of Him,—not God, but themselves, and not with Him, but with themselves. For our part, we dare not believe that God is affected in one way when He works, in another when He rests. Indeed, to say that He is affected at all, is an abuse of language, since it implies that there comes to be something in His nature which was not there before. For he who is affected is acted upon, and whatever is acted upon is changeable. In His leisure, therefore, is no laziness, indolence, inactivity; as in His work is no labour, effort, industry. He can act while He reposes, and repose while He acts. He can begin a new work with (not a new, but) an eternal design; and what He has not made before, He does not now begin to make because He repents of His former repose. But when one speaks of His former repose and subsequent operation (and I know not how men can understand these things), this "former" and "subsequent" are applied only to the things created, which formerly did not exist, and subsequently came into existence. But in God the former purpose is not altered and obliterated by the subsequent and different purpose, but by one and the same eternal and unchangeable will He effected regarding the things He created, both that formerly, so
