City of God, Book VIII
Whence it certainly follows that the student of wisdom, that is, the philosopher, will then become blessed when he shall have begun to enjoy God. For though he is not necessarily blessed who enjoys that which he loves (for many are miserable by loving that which ought not to be loved, and still more miserable when they enjoy it), nevertheless no one is blessed who does not enjoy that which he loves. For even they who love things which ought not to be loved do not count themselves blessed by loving merely, but by enjoying them. Who, then, but the most miserable will deny that he is blessed, who enjoys that which he loves, and loves the true and highest good? But the true and highest good, according to Plato, is God, and therefore he would call him a philosopher who loves God; for philosophy is directed to the obtaining of the blessed life, and he who loves God is blessed in the enjoyment of God.
Chapter 9.—Concerning that Philosophy Which Has Come Nearest to the Christian Faith.
Whatever philosophers, therefore, thought concerning the supreme God, that He is both the maker of all created things, the light by which things are known, and the good in reference to which things are to be done; that we have in Him the first principle of nature, the truth of doctrine, and the happiness of life,—whether these philosophers may be more suitably called Platonists, or whether they may give some other name to their sect; whether, we say, that only the chief men of the Ionic school, such as Plato himself, and they who have well understood him, have thought thus; or whether we also include the Italic school, on account of Pythagoras and the Pythagoreans, and all who may have held like opinions; and, lastly, whether also we include all who have been held wise men and philosophers among all nations who are discovered to have seen and taught this, be they Atlantics, Libyans, Egyptians, Indians, Persians, Chaldeans, Scythians, Gauls, Spaniards, or of other nations,—we prefer these to all other philosophers, and confess that they approach nearest to us.
Chapter 10.—That the Excellency of the Christian Religion is Above All the Science of Philosophers.
For although a Christian man instructed only in ecclesiastical literature may perhaps be ignorant of the very name of Platonists, and may not even know that there have existed two schools of philosophers speaking the Greek tongue, to wit, the Ionic and Italic, he is nevertheless not so deaf with respect to human affairs, as not to know that philosophers profess the study, and even the possession, of wisdom. He is on his guard, however, with respect to those who philosophize according to the elements of this world, not according to God, by whom the world itself was made; for he is warned by the precept of the apostle, and faithfully hears what has been said, “Beware that no one deceive you through philosophy and vain deceit, according to the elements of the world.” Then, that he may not suppose that all philosophers are such as do this, he hears the same apostle say concerning certain of them, “Because that which is known of God is manifest among them, for God has manifested it to them. For His invisible things from the creation of the world are clearly seen, being understood by the things which are made, also His eternal power and Godhead.” And, when speaking to the Athenians, after having spoken a mighty thing concerning God, which few are able to understand, “In Him we live, and move, and have our being,” he goes on to say, “As certain also of your own have said.” He knows well, too, to be on his guard against even these philosophers in their errors. For where it has been said by him, “that God has manifested to them by those things which are made His invisible things, that they might be seen by the understanding,” there it has also been said that they did not rightly worship God Himself, because they paid divine honors, which are due to Him alone, to other things also to which they ought not to have paid them,—“because, knowing God, they glorified Him not as God: neither were thankful, but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools, and changed the glory of the incorruptible God into the likeness of the image of corruptible man, and of birds, and fourfooted beasts, and creeping things;” —where the apostle would have us understand him as meaning the Romans, and Greeks, and Egyptians, who gloried in the name of wisdom; but concerning this we will dispute with them afterwards. With respect, however, to that wherein they agree with us we prefer them to all others, namely, concerning the one God, the author of this universe, who is not only above every body, being incorporeal, but also above all souls, being incorruptible—our principle, our light, our good.
And though the Christian man, being ignorant of their writings, does not use in disputation words which he has not learned,—not calling that part of philosophy natural (which is the Latin term), or physical (which is the Greek one), which treats of the investigation of nature; or that part rational, or logical, which deals with the question how truth may be discovered; or that part moral, or ethical, which concerns morals, and shows how good is to be sought, and evil to be shunned,—he is not, therefore, ignorant that it is from the one true and supremely good God that we have that nature in which we are made in the image of God, and that doctrine by which we know Him and ourselves, and that grace through which, by cleaving to Him, we are blessed.
This, therefore, is the cause why we prefer these to all the others, because, whilst other philosophers have worn out their minds and powers in seeking the causes of things, and endeavoring to discover the right mode of learning and of living, these, by knowing God, have found where resides the cause by which the universe has been constituted, and the light by which truth is to be discovered, and the fountain at which felicity is to be drunk. All philosophers, then, who have had these thoughts concerning God, whether Platonists or others, agree with us. But we have thought it better to plead our cause with the Platonists, because their writings are better known. For the Greeks, whose tongue holds the highest place among the languages of the Gentiles, are loud in their praises of these writings; and the Latins, taken with their excellence, or their renown, have studied them more heartily than other writings, and, by translating them into our tongue, have given them greater celebrity and notoriety.
Chapter 11.—How Plato Has Been Able to Approach So Nearly to Christian Knowledge.
Certain partakers with us in the grace of Christ, wonder when they hear and read that Plato had conceptions concerning God, in which they recognize considerable agreement with the truth of our religion. Some have concluded from this, that when he went to Egypt he had heard the prophet Jeremiah, or, whilst travelling in the same country, had read the prophetic scriptures, which opinion I myself have expressed in certain of my writings. But a careful calculation of dates, contained in chronological history, shows that Plato was born about a hundred years after the time in which Jeremiah prophesied, and, as he lived eighty-one years, there are found to have been about seventy years from his death to that time when Ptolemy, king of Egypt, requested the prophetic scriptures of the Hebrew people to be sent to him from Judea, and committed them to seventy Hebrews, who also knew the Greek tongue, to be translated and kept. Therefore, on that voyage of his, Plato could neither have seen Jeremiah, who was dead so long before, nor have read those same scriptures which had not yet been translated into the Greek language, of which he was a master, unless, indeed, we say that, as he was most earnest in the pursuit of knowledge, he also studied those writings through an interpreter, as he did those of the Egyptians,—not, indeed, writing a translation of them (the facilities for doing which were only gained even by Ptolemy in return for munificent acts of kindness, though fear of his kingly authority might have seemed a sufficient motive), but learning as much as he possibly could concerning their contents by means of conversation.
What warrants this supposition are the opening verses of Genesis: “In the beginning God made the heaven and earth. And the earth was invisible, and without order; and darkness was over the abyss: and the Spirit of God moved over the waters.” For in the Timæus , when writing on the formation of the world, he says that God first united earth and fire; from which it is evident that he assigns to fire a place in heaven. This opinion bears a certain resemblance to the statement, “In the beginning God made heaven and earth.” Plato next speaks of those two intermediary elements, water and air, by which the other two extremes, namely, earth and fire, were mutually united; from which circumstance he is thought to have so understood the words, “The Spirit of God moved over the waters.” For, not paying sufficient attention to the designations given by those scriptures to the Spirit of God, he may have thought that the four elements are spoken of in that place, because the air also is called spirit.
Then, as to Plato’s saying that the philosopher is a lover of God, nothing shines forth more conspicuously in those sacred writings. But the most striking thing in this connection, and that which most of all inclines me almost to assent to the opinion that Plato was not ignorant of those writings, is the answer which was given to the question elicited from the holy Moses when the words of God were conveyed to him by the angel; for, when he asked what was the name of that God who was commanding him to go and deliver the Hebrew people out of Egypt, this answer was given: “I am who am; and thou shalt say to the children of Israel, He who is sent me unto you;” as though compared with Him that truly is, because He is unchangeable, those things which have been created mutable are not,—a truth which Plato zealously held, and most diligently commended. And I know not whether this sentiment is anywhere to be found in the books of those who were before Plato, unless in that book where it is said, “I am who am; and thou shalt say to the children of Israel, who is sent me unto you.”
Chapter 12.—That Even the Platonists, Though They Say These Things Concerning the One True God, Nevertheless Thought that Sacred Rites Were to Be Performed in Honor of Many Gods.
