The City of God Book XIV: Two loves, two cities

We have already stated in the preceding books that God, desiring not only that the human race might be able by their similarity of nature to associate with one another, but also that they might be bound together in harmony and peace by the ties of relationship, was pleased to derive all men from one individual, and created man with such a nature that the members of the race should not have died, had not the two first (of whom the one was created out of nothing, and the other out of him) merited this by their disobedience; for by them so great a sin was committed, that by it the human nature was altered for the worse, and was transmitted also to their posterity, liable to sin and subject to death. And the kingdom of death so reigned over men, that the deserved penalty of sin would have hurled all headlong even into the second death, of which there is no end, had not the undeserved grace of God saved some therefrom. And thus it has come to pass, that though there are very many and great nations all over the earth, whose rites and customs, speech, arms, and dress, are distinguished by marked differences, yet there are no more than two kinds of human society, which we may justly call two cities, according to the language of our Scriptures. The one consists of those who wish to live after the flesh, the other of those who wish to live after the spirit; and when they severally achieve what they wish, they live in peace, each after their kind.

When, therefore, man lives according to man, not according to God, he is like the devil. Because not even an angel might live according to an angel, but only according to God, if he was to abide in the truth, and speak God's truth and not his own lie. And of man, too, the same apostle says in another place, "If the truth of God hath more abounded through my lie;"—"my lie," he said, and "God's truth." When, then, a man lives according to the truth, he lives not according to himself, but according to God; for He was God who said, "I am the truth." When, therefore, man lives according to himself,—that is, according to man, not according to God,—assuredly he lives according to a lie; not that man himself is a lie, for God is his author and creator, who is certainly not the author and creator of a lie, but because man was made upright, that he might not live according to himself, but according to Him that made him,—in other words, that he might do His will and not his own; and not to live as he was made to live, that is a lie. For he certainly desires to be blessed even by not living so that he may be blessed. And what is a lie if this desire be not? Wherefore it is not without meaning said that all sin is a lie. For no sin is committed save by that desire or will by which we desire that it be well with us, and shrink from it being ill with us. That, therefore, is a lie which we do in order that it may be well with us, but which makes us more miserable than we were. And why is this, but because the source of man's happiness lies only in God, whom he abandons when he sins, and not in himself, by living according to whom he sins?

In enunciating this proposition of ours, then, that because some live according to the flesh and others according to the spirit there have arisen two diverse and conflicting cities, we might equally well have said, "because some live according to man, others according to God." For Paul says very plainly to the Corinthians, "For whereas there is among you envying and strife, are ye not carnal, and walk according to man?" So that to walk according to man and to be carnal are the same; for by flesh, that is, by a part of man, man is meant. For before he said that those same persons were animal whom afterwards he calls carnal, saying, "For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. Now we have received not the spirit of this world, but the Spirit which is of God; that we might know the things which are freely given to us of God. Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. But the animal man perceiveth not the things of the Spirit of God; for they are foolishness unto him." It is to men of this kind, then, that is, to animal men, he shortly after says, "And I, brethren, could not speak unto you as unto spiritual, but as unto carnal." And this is to be interpreted by the same usage, a part being taken for the whole. For both the soul and the flesh, the component parts of man, can be used to signify the whole man; and so the animal man and the carnal man are not two different things, but one and the same thing, viz. man living according to man. In the same way it is nothing else than men that are meant either in the words, "By the deeds of the law there shall no flesh be justified;" or in the words, "Seventy-five souls went down into Egypt with Jacob." In the one passage, "no flesh" signifies "no man;" and in the other, by "seventy-five souls" seventy-five men are meant. And the expression, "not in words which man's wisdom teacheth," might equally be "not in words which fleshly wisdom teacheth;" and the expression, "ye walk according to man," might be "according to the flesh." And this is still more apparent in the words which followed: "For while one saith, I am of Paul, and another, I am of Apollos, are ye not men?" The same thing which he had before expressed by "ye are animal," "ye are carnal," he now expresses by "ye are men;" that is, ye live according to man, not according to God, for if you lived according to Him, you should be gods.

Accordingly, two cities have been formed by two loves: the earthly by the love of self, even to the contempt of God; the heavenly by the love of God, even to the contempt of self. The former, in a word, glories in itself, the latter in the Lord. For the one seeks glory from men; but the greatest glory of the other is God, the witness of conscience. The one lifts up its head in its own glory; the other says to its God, "Thou art my glory, and the lifter up of mine head." In the one, the princes and the nations it subdues are ruled by the love of ruling; in the other, the princes and the subjects serve one another in love, the latter obeying, while the former take thought for all. The one delights in its own strength, represented in the persons of its rulers; the other says to its God, "I will love Thee, O Lord, my strength." And therefore the wise men of the one city, living according to man, have sought for profit to their own bodies or souls, or both, and those who have known God "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,"—that is, glorying in their own wisdom, and being possessed by pride,—"they became fools, and changed the glory of the incorruptible God into an image made like to corruptible man, and to birds, and four-footed beasts, and creeping things." For they were either leaders or followers of the people in adoring images, "and worshipped and served the creature more than the Creator, who is blessed for ever." But in the other city there is no human wisdom, but only godliness, which offers due worship to the true God, and looks for its reward in the society of the saints, of holy angels as well as holy men, "that God may be all in all."
