BOOK XIX. Chapter 14. Of the Order and Law Which Obtain in Heaven and Earth, Whereby It Comes to Pass that Human Society Is Served by Those Who Rule It.

The whole use, then, of things temporal has a reference to this result of earthly peace in the earthly community, while in the city of God it is connected with eternal peace. And therefore, if we were irrational animals, we should desire nothing beyond the proper arrangement of the parts of the body and the satisfaction of the appetites — nothing, therefore, but bodily comfort and abundance of pleasures, that the peace of the body might contribute to the peace of the soul. For if bodily peace be awanting, a bar is put to the peace even of the irrational soul, since it cannot obtain the gratification of its appetites. And these two together help out the mutual peace of soul and body, the peace of harmonious life and health. For as animals, by shunning pain, show that they love bodily peace, and, by pursuing pleasure to gratify their appetites, show that they love peace of soul, so their shrinking from death is a sufficient indication of their intense love of that peace which binds soul and body in close alliance. But, as man has a rational soul, he subordinates all this which he has in common with the beasts to the peace of his rational soul, that his intellect may have free play and may regulate his actions, and that he may thus enjoy the well-ordered harmony of knowledge and action which constitutes, as we have said, the peace of the rational soul. And for this purpose he must desire to be neither molested by pain, nor disturbed by desire, nor extinguished by death, that he may arrive at some useful knowledge by which he may regulate his life and manners. But, owing to the liability of the human mind to fall into mistakes, this very pursuit of knowledge may be a snare to him unless he has a divine Master, whom he may obey without misgiving, and who may at the same time give him such help as to preserve his own freedom. And because, so long as he is in this mortal body, he is a stranger to God, he walks by faith, not by sight; and he therefore refers all peace, bodily or spiritual or both, to that peace which mortal man has with the immortal God, so that he exhibits the well-ordered obedience of faith to eternal law. But as this divine Master inculcates two precepts — the love of God and the love of our neighbor — and as in these precepts a man finds three things he has to love —God, himself, and his neighbor — and that he who loves God loves himself thereby, it follows that he must endeavor to get his neighbor to love God, since he is ordered to love his neighbor as himself. He ought to make this endeavor in behalf of his wife, his children, his household, all within his reach, even as he would wish his neighbor to do the same for him if he needed it; and consequently he will be at peace, or in well-ordered concord, with all men, as far as in him lies. And this is the order of this concord, that a man, in the first place, injure no one, and, in the second, do good to every one he can reach. Primarily, therefore, his own household are his care, for the law of nature and of society gives him readier access to them and greater opportunity of serving them. And hence the apostle says, Now, if any provide not for his own, and specially for those of his own house, he has denied the faith, and is worse than an infidel. 1 Timothy 5:8 This is the origin of domestic peace, or the well-ordered concord of those in the family who rule and those who obey. For they who care for the rest rule — the husband the wife, the parents the children, the masters the servants; and they who are cared for obey — the women their husbands, the children their parents, the servants their masters. But in the family of the just man who lives by faith and is as yet a pilgrim journeying on to the celestial city, even those who rule serve those whom they seem to command; for they rule not from a love of power, but from a sense of the duty they owe to others — not because they are proud of authority, but because they love mercy.

Chapter 15. Of the Liberty Proper to Man's Nature, and the Servitude Introduced by Sin — A Servitude in Which the Man Whose Will is Wicked is the Slave of His Own Lust, Though He is Free So Far as Regards Other Men.

This is prescribed by the order of nature: it is thus that God has created man. For let them, He says, have dominion over the fish of the sea, and over the fowl of the air, and over every creeping thing which creeps on the earth. Genesis 1:26 He did not intend that His rational creature, who was made in His image, should have dominion over anything but the irrational creation, — not man over man, but man over the beasts. And hence the righteous men in primitive times were made shepherds of cattle rather than kings of men, God intending thus to teach us what the relative position of the creatures is, and what the desert of sin; for it is with justice, we believe, that the condition of slavery is the result of sin. And this is why we do not find the word slave in any part of Scripture until righteous Noah branded the sin of his son with this name. It is a name, therefore, introduced by sin and not by nature. The origin of the Latin word for slave is supposed to be found in the circumstance that those who by the law of war were liable to be killed were sometimes preserved by their victors, and were hence called servants. And these circumstances could never have arisen save through sin. For even when we wage a just war, our adversaries must be sinning; and every victory, even though gained by wicked men, is a result of the first judgment of God, who humbles the vanquished either for the sake of removing or of punishing their sins. Witness that man of God, Daniel, who, when he was in captivity, confessed to God his own sins and the sins of his people, and declares with pious grief that these were the cause of the captivity. Daniel ix The prime cause, then, of slavery is sin, which brings man under the dominion of his fellow — that which does not happen save by the judgment of God, with whom is no unrighteousness, and who knows how to award fit punishments to every variety of offense. . . .

Chapter 17. What Produces Peace, and What Discord, Between the Heavenly and Earthly Cities.

But the families which do not live by faith seek their peace in the earthly advantages of this life; while the families which live by faith look for those eternal blessings which are promised, and use as pilgrims such advantages of time and of earth as do not fascinate and divert them from God, but rather aid them to endure with greater ease, and to keep down the number of those burdens of the corruptible body which weigh upon the soul. Thus the things necessary for this mortal life are used by both kinds of men and families alike, but each has its own peculiar and widely different aim in using them. The earthly city, which does not live by faith, seeks an earthly peace, and the end it proposes, in the well-ordered concord of civic obedience and rule, is the combination of men's wills to attain the things which are helpful to this life. The heavenly city, or rather the part of it which sojourns on earth and lives by faith, makes use of this peace only because it must, until this mortal condition which necessitates it shall pass away. Consequently, so long as it lives like a captive and a stranger in the earthly city, though it has already received the promise of redemption, and the gift of the Spirit as the earnest of it, it makes no scruple to obey the laws of the earthly city, whereby the things necessary for the maintenance of this mortal life are administered; and thus, as this life is common to both cities, so there is a harmony between them in regard to what belongs to it. But, as the earthly city has had some philosophers whose doctrine is condemned by the divine teaching, and who, being deceived either by their own conjectures or by demons, supposed that many gods must be invited to take an interest in human affairs, and assigned to each a separate function and a separate department — to one the body, to another the soul; and in the body itself, to one the head, to another the neck, and each of the other members to one of the gods; and in like manner, in the soul, to one god the natural capacity was assigned, to another education, to another anger, to another lust; and so the various affairs of life were assigned — cattle to one, grain to another, wine to another, oil to another, the woods to another, money to another, navigation to another, wars and victories to another, marriages to another, births and fecundity to another, and other things to other gods: and as the celestial city, on the other hand, knew that one God only was to be worshipped, and that to Him alone was due that service which the Greeks call λατρεία, and which can be given only to a god, it has come to pass that the two cities could not have common laws of religion, and that the heavenly city has been compelled in this matter to dissent, and to become obnoxious to those who think differently, and to stand the brunt of their anger and hatred and persecutions, except in so far as the minds of their enemies have been alarmed by the multitude of the Christians and quelled by the manifest protection of God accorded to them. This heavenly city, then, while it sojourns on earth, calls citizens out of all nations, and gathers together a society of pilgrims of all languages, not scrupling about diversities in the manners, laws, and institutions whereby earthly peace is secured and maintained, but recognizing that, however various these are, they all tend to one and the same end of earthly peace. It therefore is so far from rescinding and abolishing these diversities, that it even preserves and adopts them, so long only as no hindrance to the worship of the one supreme and true God is thus introduced. Even the heavenly city, therefore, while in its state of pilgrimage, avails itself of the peace of earth, and, so far as it can without injuring faith and godliness, desires and maintains a common agreement among men regarding the acquisition of the necessaries of life, and makes this earthly peace bear upon the peace of heaven; for this alone can be truly called and esteemed the peace of the reasonable creatures, consisting as it does in the perfectly ordered and harmonious enjoyment of God and of one another in God. When we shall have reached that peace, this mortal life shall give place to one that is eternal, and our body shall be no more this animal body which by its corruption weighs down the soul, but a spiritual body feeling no want, and in all its members subjected to the will. In its pilgrim state the heavenly city possesses this peace by faith; and by this faith it lives righteously when it refers to the attainment of that peace every good action towards God and man; for the life of the city is a social life.

Chapter 24. The Definition Which Must Be Given of a People and a Republic, in Order to Vindicate the Assumption of These Titles by the Romans and by Other Kingdoms.

But if we discard this definition of a people, and, assuming another, say that a people is an assemblage of reasonable beings bound together by a common agreement as to the objects of their love, then, in order to discover the character of any people, we have only to observe what they love. Yet whatever it loves, if only it is an assemblage of reasonable beings and not of beasts, and is bound together by an agreement as to the objects of love, it is reasonably called a people; and it will be a superior people in proportion as it is bound together by higher interests, inferior in proportion as it is bound together by lower. According to this definition of ours, the Roman people is a people, and its good is without doubt a commonwealth or republic. But what its tastes were in its early and subsequent days, and how it declined into sanguinary seditions and then to social and civil wars, and so burst asunder or rotted off the bond of concord in which the health of a people consists, history shows, and in the preceding books I have related at large. And yet I would not on this account say either that it was not a people, or that its administration was not a republic, so long as there remains an assemblage of reasonable beings bound together by a common agreement as to the objects of love. But what I say of this people and of this republic I must be understood to think and say of the Athenians or any Greek state, of the Egyptians, of the early Assyrian Babylon, and of every other nation, great or small, which had a public government. For, in general, the city of the ungodly, which did not obey the command of God that it should offer no sacrifice save to Him alone, and which, therefore, could not give to the soul its proper command over the body, nor to the reason its just authority over the vices, is void of true justice.

Chapter 26. Of the Peace Which is Enjoyed by the People that are Alienated from God, and the Use Made of It by the People of God in the Time of Its Pilgrimage.

Wherefore, as the life of the flesh is the soul, so the blessed life of man is God, of whom the sacred writings of the Hebrews say, Blessed is the people whose God is the Lord. Miserable, therefore, is the people which is alienated from God. Yet even this people has a peace of its own which is not to be lightly esteemed, though, indeed, it shall not in the end enjoy it, because it makes no good use of it before the end. But it is our interest that it enjoy this peace meanwhile in this life; for as long as the two cities are commingled, we also enjoy the peace of Babylon. For from Babylon the people of God is so freed that it meanwhile sojourns in its company. And therefore the apostle also admonished the Church to pray for kings and those in authority, assigning as the reason, that we may live a quiet and tranquil life in all godliness and love. And the prophet Jeremiah, when predicting the captivity that was to befall the ancient people of God, and giving them the divine command to go obediently to Babylonia, and thus serve their God, counselled them also to pray for Babylonia, saying, In the peace thereof shall you have peace, Jeremiah 29:7 — the temporal peace which the good and the wicked together enjoy.
