The City of God stands as Augustine's masterwork of theological defense and construction, written over thirteen years in response to accusations that Christianity brought ruin upon Rome. This first volume contains the first ten books of sustained refutation—demolishing pagan claims that traditional worship secured either temporal prosperity or eternal happiness—followed by the beginning of his positive vision in Books Eleven through Thirteen, where he traces the origin of two societal orders to the primordial division among the angels. What emerges is not merely an apology for Christianity but a philosophy of history that subordinate the fate of empires to the hidden providence of the one true God, whose sovereignty extends from creation through the fall to the final judgment.
The citizens of the heavenly city, by contrast, look forward to eternal life in a realm where none are born and none die, where true felicity is not a goddess but a gift of God. The examples of Roman virtue serve a useful purpose for Christians: they provoke a salutary shame. If the Romans endured poverty, sacrificed their children, faced torture and death for a terrestrial city and human glory, how much more should Christians be willing to do for the heavenly city and eternal life? Augustine catalogs the heroic deeds of Roman legend: Brutus putting his sons to death for the sake of liberty; Torquatus slaying his son for disobeying orders; Camillus returning from exile to save his ungrateful country; Mucius thrusting his hand into fire to intimidate an enemy king; Curtius riding armed into a chasm to satisfy an oracle; the Decii dedicating themselves to death in battle; Regulus returning to certain torture rather than break his oath; Fabricius and Cincinnatus refusing wealth and power to remain in poverty. These men did such things for a city that would pass away, for a glory that fades. Christians, who hope for a city that endures forever, should not boast if they have done less.
Augustine distinguishes between the desire for glory and the desire for domination. Those who seek glory, even from human judges, strive to avoid displeasing those whose opinion they value. This can lead to genuine virtue, or at least to its appearance. But those who seek domination without regard for reputation often pursue their ends through open crimes. The worst tyrants combine cruelty with luxury, exceeding even the beasts in vice. Yet even tyrants reign by God’s permission, as Scripture affirms: “By me kings reign, and tyrants possess the land.” God makes the hypocrite to rule because of the people’s perversity. The hidden judgments of God’s providence often exceed our understanding, but this much is clear: true virtue cannot serve human praise any more than it can serve bodily pleasure. The philosophers rightly mock the notion of virtue enslaved to pleasure; they should equally reject virtue enslaved to glory.
