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,”769 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.”770 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.

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 fulfil the law of Christ.”771 In like manner it is said elsewhere, “Warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men. See that none render evil for evil unto any man.”772 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.”773 And elsewhere, “Let not the sun go down upon your wrath.”774 And in the Gospel, “If thy brother shall trespass against thee, go and tell him his fault between thee and him alone.”775 So too of sins which may create scandal the apostle says, “Them that sin rebuke before all, that others also may fear.”776 For this purpose, and that we may keep that peace without which no man can see the Lord,777 many precepts are given which carefully inculcate mutual forgiveness; among which we may number that terrible word in which the servant is ordered to pay
