Of these two first parents of the human race, then, Cain was the first-born, and he belonged to the city of men; after him was born Abel, who belonged to the city of God. For as in the individual the truth of the apostle's statement is discerned, "that is not first which is spiritual, but that which is natural, and afterward that which is spiritual,"¹ whence it comes to pass that each man, being derived from a condemned stock, is first of all born of Adam evil and carnal, and becomes good and spiritual only afterwards, when he is grafted into Christ by regeneration: so was it in the human race as a whole. When these two cities began to run their course by a series of deaths and births, the citizen of this world was the first-born, and after him the stranger in this world, the citizen of the city of God, predestinated by grace, elected by grace, by grace a stranger below, and by grace a citizen above. By grace,-for so far as regards himself he is sprung from the same mass, all of which is condemned in its origin: but God, like a potter (for this comparison is introduced by the apostle judiciously, and not without thought), of the same lump made one vessel to honor, another to dishonor.² But first the vessel to dishonor was made, and after it another to honor. For in each individual, as I have already said, there is first of all that which is reprobate, that from which we must begin, but in which we need not necessarily remain; afterwards is that which is well-approved, to which we may by advancing attain, and in which, when we have reached it we may abide. Not, indeed, that every wicked man shall be good, but that no one will be good who was not first of all wicked but the sooner any one becomes a good man, the more speedily does he receive this title, and abolish the old name in the new. Accordingly, it is recorded of Cain that he built a city,³ but Abel, being a sojourner, built none. For the city of the saints is above, although here below it begets citizens, in whom it sojourns till the time of its reign arrives, when it shall gather together all in the day of the resurrection; and then shall the promised kingdom be given to them, in which they shall reign with their Prince, the King of the ages, time without end.

Chapter 2.-Of the Children of the Flesh and the Children of the Promise.

There was indeed on earth, so long as it was needed, a symbol and foreshadowing image of this city, which served the purpose of reminding men that such a city was to be rather than of making it present; and this image was itself called the holy city, as a symbol of the future city, though not itself the reality. Of this city which served as an image, and of that free city it typified, Paul writes to the Galatians in these terms: "Tell me, ye that desire to be under the law, do ye not hear the law? For it is written, that Abraham had two sons, the one by a bond maid, the other by a free woman. But he who was of the bond woman was born after the flesh, but he of the free woman was by promise. Which things are an allegory:⁴ for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar. For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. But Jerusalem which is above is free, which is the mother of us all. For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not for the desolate hath many more children than she which hath an husband. Now we, brethren, as Isaac was, are the children of promise. But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now. Nevertheless, what saith the Scripture? Cast out the bond woman and her son: for the son of the bond woman shall not be heir with the son of the free woman. And we, brethren, are not children of the bond woman, but of the free, in the liberty wherewith Christ hath made us free."⁵ This interpretation of the passage, handed down to us with apostolic authority, shows how we ought to understand the Scriptures of the two covenants-the old and the new. One portion of the earthly city became an image of the heavenly city, not having a significance of its own, but signifying another city, and therefore serving, or" being in bondage." For it was founded not for its own sake, but to prefigure another city; and this shadow of a city was also itself foreshadowed by another preceding figure. For Sarah's handmaid Agar, and her son, were an image of this image. And as the shadows were to pass away when the full light came, Sarah, the free woman, who prefigured the free city (which again was also prefigured in another way by that shadow of a city Jerusalem), therefore said, "Cast out the bond woman and her son; for the son of the bond woman shall not be heir with my son Isaac," or, as the apostle says, "with the son of the free woman." In the earthly city, then, we find two things-its own obvious presence, and its symbolic presentation of the heavenly city. Now citizens are begotten to the earthly city by nature vitiated by sin, but to the heavenly city by grace freeing nature from sin; whence the former are called "vessels of wrath," the latter "vessels of mercy."⁶ And this was typified in the two sons of Abraham,-Ishmael, the son of Agar the handmaid, being born according to the flesh, while Isaac was born of the free woman Sarah, according to the promise. Both, indeed, were of Abraham's seed; but the one was begotten by natural law, the other was given by gracious promise. In the one birth, human action is revealed; in the other, a divine kindness comes to light.

Chapter 3.-That Sarah's Barrennesswasmade Productive by God's Grace.

Sarah, in fact, was barren; and, despairing of offspring, and being resolved that she would have at least through her handmaid that blessing she saw she could not in her own person procure, she gave her handmaid to her husband, to whom she herself had been unable to bear children. From him she required this conjugal duty, exercising her own right in another's womb. And thus Ishmael was born according to the common law of human generation, by sexual intercourse. Therefore it is said that he was born "according to the flesh,"-not because such births are not the gifts of God, nor His handiwork, whose creative wisdom" reaches," as it is written, "from one end to another mightily, and sweetly cloth she order all things,"⁷ but because, in a case in which the gift of God, which was not due to men and was the gratuitous largess of grace, was to be conspicuous, it was requisite that a son be given in a way which no effort of nature could compass. Nature denies children to persons of the age which Abraham and Sarah had now reached; besides that, in Sarah's case, she was barren even in her prime. This nature, so constituted that offspring could not be looked for, symbolized the nature of the human race vitiated by sin and by just consequence condemned. which deserves no future felicity. Fitly, therefore, does Isaac, the child of promise, typify the children of grace, the citizens of the free city, who dwell together in everlasting peace, in which self-love and self-will have no place, but a ministering love that rejoices in the common joyall, of many hearts makes one, that is to say, secures a perfect concord.

Chapter 4.-Of the Conflict and Peace of the Earthly City.

But the earthly city, which shall not be everlasting (for it will no longer be a city when it has been committed to the extreme penalty), has its good in this world, and rejoices in it with such joy as such things can afford. But as this is not a good which can discharge its devotees of all distresses, this city is often divided against itself by litigations, wars, quarrels, and such victories as are either life-destroying or short-lived. For each part of it that arms against another part of it seeks to triumph over the nations through itself in bondage to vice. If, when it has conquered, it is inflated with pride, its victory is life-destroying; but if it turns its thoughts upon the common casualties of our mortal condition, and is rather anxious concerning the disasters that may befall it than elated with the successes already achieved, this victory, though of a higher kind, is still only shot-lived; for it cannot abidingly rule over those whom it has victoriously subjugated. But the things which this city desires cannot justly be said to be evil, for it is itself, in its own kind, better than all other human good. For it desires earthly peace for the sake of enjoying earthly goods, and it makes war in order to attain to this peace; since, if it has conquered, and there remains no one to resist it, it enjoys a peace which it had not while there were opposing parties who contested for the enjoyment of those things which were too small to satisfy both. This peace is purchased by toilsome wars; it is obtained by what they style a glorious victory. Now, when victory remains with the party which had the juster cause, who hesitates to congratulate the victor, and styleit a desirable peace? These things, then, are good things, and without doubt the gifts of God. But if they neglect the better things of the heavenly city, which are secured by eternal victory and peace never-ending, and so inordinately covet these present good things that they believe them to be the only desirable things, or love them better than those things which are believed to be better,-if this be so, then it is necessary that misery follow and ever increase.

Chapter 5.-Of the Fratricidal Act of the Founder of the Earthly City, and the Corresponding Crime of the Founder of Rome.

Thus the founder of the earthly city was a fratricide. Overcome with envy, he slew his own brother, a citizen of the eternal city, and a sojourner on earth. So that we cannot be surprised that this first specimen, or, as the Greeks say, archetype of crime, should, long afterwards, find a corresponding crime at the foundation of that city which was destined to reign over so many nations, and be the head of this earthly city of which we speak. For of that city also, as one of their poets has mentioned, "the first walls were stained with a brother's blood,"⁸ or, as Roman history records, Remus was slain by his brother Romulus. And thus there is no difference between the foundation of this city and of the earthly city, unless it be that Romulus and Remus were both citizens of the earthly city. Both desired to have the glory of founding the Roman republic, but both could not have as much glory as if one only claimed it; for he who wished to have the glory of ruling would certainly rule less if his power were shared by a living consort. In order, therefore, that the whole glory might be enjoyed by one, his consort was removed; and by this crime the empire was made larger indeed, but inferior, while otherwise it would have been less, but better. Now these brothers, Cain and Abel, were not both animated by the same earthly desires, nor did the murderer envy the other because he feared that, by both ruling, his own dominion would be curtailed,-for Abel was not solicitous to rule in that city which his brother built,-he was moved by that diabolical, envious hatred with which the evil regard the good, for no other reason than because they are good while themselves are evil. For the possession of goodness is by no means diminished by being shared with a partner either permanent or temporarily assumed; on the contrary, the possession of goodness is increased in proportion to the concord and charity of each of those who share it. In short, he who is unwilling to share this possession cannot have it; and he who is most willing to admit others to a share of it will have the greatest abundance to himself. The quarrel, then, between Romulus and Remus shows how the earthly city is divided against itself; that which fell out between Cain and Abel illustrated the hatred that subsists between the two cities, that of God and that of men. The wicked war with the wicked; the good also war with the wicked. But with the good, good men, or at least perfectly good men, cannot war;though, while only going on towards perfection, they war to this extent, that every good man resists others in those points in which he resists himself. And in each individual "the flesh lusteth against the spirit, and the spirit against the flesh."⁹ This spiritual lusting, therefore, can be at war with the carnal lust of another man; or carnal lust may be at war with the spiritual desires of another, in some such way as good and wicked men are at war; or, still more certainly, the carnal lusts of two men, good but not yet perfect, contend together, just as the wicked contend with the wicked, until the health of those who are under the treatment of grace attains final victory.

Chapter 6.-Of the Weaknesses Which Even the Citizens of the City of God Suffer During This Earthly Pilgrimage in Punishment of Sin, and of Which They are Healed by God's Care.

This sickliness-that is to say, that disobedience of which we spoke in the fourteenth book-is the punishment of the first disobedience. It is therefore not nature, but vice; and therefore it is said to the good who are growing in grace, and living in this pilgrimage by faith, "Bear ye one another's burdens, and so fulfill the law of Christ."¹⁰ In like manner it is said elsewhere, "Warn them that are unruly, comfort the feeble-minded, sup port the weak, be patient toward all men. See that none render evil for evil unto any man."¹¹ And in another place, "If a man be overtaken in a fault, ye which are spiritual restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted."¹² And elsewhere, "Let not the sun go down upon your wrath."¹³ And in the Gospel, "If thy brother shall trespass against thee, go and tell him his fault between thee and him alone."¹⁴ So too of sins which may create scandal the apostle says, "Them that sin rebuke before all, that others also may fear."¹⁵ For this purpose, and that we may keep that peace without which no man can see the Lord,¹⁶ many precepts are given which carefully inculcatemutual forgiveness; among which we may number that terrible word in which the servant is ordered to pay his formerly remitted debt of ten thousand talents, because he did not remit to his fellow-servant his debt of two hundred pence. To which parable the Lord Jesus added the words, "So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother."¹⁷ It is thus the citizens of the city of God are healed while still they sojourn in this earth and sigh for the peace of their heavenly country. The Holy Spirit, too, works within, that the medicine externally applied may have some good result. Otherwise, even though God Himself make use of the creatures that are subject to Him, and in some human form address our human senses, whether we receive those impressions in sleep or in some external appearance, still, if He does not by His own inward grace sway and act upon the mind, no preaching of the truth is of any avail. But this God does, distinguishing between the vessels of wrath and the vessels of mercy, by His own very secret but very just providence. When He Himself aids the soul in His own hidden and wonderful ways, and the sin which dwells in our members, and is, as the apostle teaches, rather the punishment of sin, does not reignin our mortal body to obey the lusts of it, and when we no longer yield our members as instruments of unrighteousness,¹⁸ then the soul is converted from its own evil and selfish desires, and, God possessing it, it possesses itself in peace even in this life, and afterwards, with perfected health and endowed with immortality, will reign without sin in peace everlasting.
