City of God, Book XII
Even though reason could not refute, faith would smile at these argumentations, with which the godless endeavor 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 refer 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.” 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. His leisure, therefore, is no laziness, indolence, inactivity; as in His work is no labor, 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 long as they were not, they should not be, and that subsequently, when they began to be, they should come into existence. And thus, perhaps, He would show, in a very striking way, to those who have eyes for such things, how independent He is of what He makes, and how it is of His own gratuitous goodness He creates, since from eternity He dwelt without creatures in no less perfect a blessedness.
Chapter 18.—Against Those Who
Assert that Things that are Infinite Cannot Be Comprehended by the Knowledge of God.
As for their other assertion, that God’s knowledge cannot comprehend things infinite, it only remains for them to affirm, in order that they may sound the depths of their impiety, that God does not know all numbers. For it is very certain that they are infinite; since, no matter of what number you suppose an end to be made, this number can be, I will not say, increased by the addition of one more, but however great it be, and however vast be the multitude of which it is the rational and scientific expression, it can still be not only doubled, but even multiplied. Moreover, each number is so defined by its own properties, that no two numbers are equal. They are therefore both unequal and different from one another; and while they are simply finite, collectively they are infinite. Does God, therefore, not know numbers on account of this infinity; and does His knowledge extend only to a certain height in numbers, while of the rest He is ignorant? Who is so left to himself as to say so? Yet they can hardly pretend to put numbers out of the question, or maintain that they have nothing to do with the knowledge of God; for Plato, their great authority, represents God as framing the world on numerical principles: and in our books also it is said to God, “Thou hast ordered all things in number, and measure, and weight.” The prophet also says, “Who bringeth out their host by number.” And the Saviour says in the Gospel, “The very hairs of your head are all numbered.” Far be it, then, from us to doubt that all number is known to Him “whose understanding,” according to the Psalmist, “is infinite.” The infinity of number, though there be no numbering of infinite numbers, is yet not incomprehensible by Him whose understanding is infinite. And thus, if everything which is comprehended is defined or made finite by the comprehension of him who knows it, then all infinity is in some ineffable way made finite to God, for it is comprehensible by His knowledge. Wherefore, if the infinity of numbers cannot be infinite to the knowledge of God, by which it is comprehended, what are we poor creatures that we should presume to fix limits to His knowledge, and say that unless the same temporal thing be repeated by the same periodic revolutions, God cannot either foreknow His creatures that He may make them, or know them when He has made them?
God, whose knowledge is simply manifold, and uniform in its variety, comprehends all incomprehensibles with so incomprehensible a comprehension, that though He willed always to make His later works novel and unlike what went before them, He could not produce them without order and foresight, nor conceive them suddenly, but by His eternal foreknowledge.
Chapter 19.—Of Worlds Without
End, or Ages of Ages.
I do not presume to determine whether God does so, and whether these times which are called “ages of ages” are joined together in a continuous series, and succeed one another with a regulated diversity, and leave exempt from their vicissitudes only those who are freed from their misery, and abide without end in a blessed immortality; or whether these are called “ages of ages,” that we may understand that the ages remain unchangeable in God’s unwavering wisdom, and are the efficient causes, as it were, of those ages which are being spent in time. Possibly “ages” is used for “age,” so that nothing else is meant by “ages of ages” than by “age of age,” as nothing else is meant by “heavens of heavens” than by “heaven of heaven.” For God called the firmament, above which are the waters, “Heaven,” and yet the psalm says, “Let the waters that are above the heavens praise the name of the Lord.” Which of these two meanings we are to attach to “ages of ages,” or whether there is not some other and better meaning still, is a very profound question; and the subject we are at present handling presents no obstacle to our meanwhile deferring the discussion of it, whether we may be able to determine anything about it, or may only be made more cautious by its further treatment, so as to be deterred from making any rash affirmations in a matter of such obscurity. For at present we are disputing the opinion that affirms the existence of those periodic revolutions by which the same things are always recurring at intervals of time. Now whichever of these suppositions regarding the “ages of ages” be the true one, it avails nothing for the substantiating of those cycles; for whether the ages of ages be not a repetition of the same world, but different worlds succeeding one another in a regulated connection, the ransomed souls abiding in well-assured bliss without any recurrence of misery, or whether the ages of ages be the eternal causes which rule what shall be and is in time, it equally follows, that those cycles which bring round the same things have no existence; and nothing more thoroughly explodes them than the fact of the eternal life of the saints.
Chapter 20.—Of the Impiety of
Those Who Assert that the Souls Which Enjoy True and Perfect Blessedness, Must Yet Again and Again in These Periodic Revolutions Return to Labor and Misery.
What pious ears could bear to hear that after a life spent in so many and severe distresses (if, indeed, that should be called a life at all which is rather a death, so utter that the love of this present death makes us fear that death which delivers us from it,) that after evils so disastrous, and miseries of all kinds have at length been expiated and finished by the help of true religion and wisdom, and when we have thus attained to the vision of God, and have entered into bliss by the contemplation of spiritual light and participation in His unchangeable immortality, which we burn to attain,—that we must at some time lose all this, and that they who do lose it are cast down from that eternity, truth, and felicity to infernal mortality and shameful foolishness, and are involved in accursed woes, in which God is lost, truth held in detestation, and happiness sought in iniquitous impurities? and that this will happen endlessly again and again, recurring at fixed intervals, and in regularly returning periods? and that this everlasting and ceaseless revolution of definite cycles, which remove and restore true misery and deceitful bliss in turn, is contrived in order that God may be able to know His own works, since on the one hand He cannot rest from creating and on the other, cannot know the infinite number of His creatures, if He always makes creatures? Who, I say, can listen to such things? Who can accept or suffer them to be spoken? Were they true, it were not only more prudent to keep silence regarding them, but even (to express myself as best I can) it were the part of wisdom not to know them. For if in the future world we shall not remember these things, and by this oblivion be blessed, why should we now increase our misery, already burdensome enough, by the knowledge of them? If, on the other hand, the knowledge of them will be forced upon us hereafter, now at least let us remain in ignorance, that in the present expectation we may enjoy a blessedness which the future reality is not to bestow; since in this life we are expecting to obtain life everlasting, but in the world to come are to discover it to be blessed, but not everlasting.
