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.
To demonstrate how unprecedented this clemency was, Augustine surveys the history of war, beginning with the fall of Troy. He cites Virgil’s account, familiar to every educated Roman, in which Priam is slaughtered at the altar and the Greeks desecrate the temples, dragging the image of Pallas from her shrine. The gods of Troy could not protect their own defenders; rather, the defenders protected the gods, and when the defenders fell, the gods were carried away as spoil. What use is a deity that cannot guard its guardians? The Romans, who prided themselves on clemency toward the vanquished, never extended that clemency to those who fled to temples. Caesar himself described the universal custom of war: virgins violated, children torn from parents, temples plundered, slaughter and burning everywhere. Marcellus, though he wept over Syracuse and issued an edict protecting chastity, still allowed the city to be sacked according to the custom of war, with no exemption for sacred places. Fabius, celebrated for leaving the “angry gods” to the Tarentines, yet did not spare the vanquished for the sake of those gods. The historians who recorded every detail of Roman virtue would surely have noted such an unprecedented act of mercy had it occurred. Therefore, the sparing of those who fled to Christian churches was something new under the sun—a restraint upon barbarian fury that must be attributed to the name of Christ.
Having established that the mercy shown in the churches was divine in origin, Augustine turns to address the deeper question of why God permits calamity to befall both the righteous and the wicked. He argues that the goods and ills of this present life are common to both, just as the sun rises and the rain falls on the just and the unjust alike. This arrangement serves a providential purpose: the good are not led to covet worldly happiness as their ultimate reward, nor are they driven to despair when adversity strikes. The same affliction proves and purifies the righteous while it damns and ruins the wicked. As fire makes gold bright but causes chaff to smoke, as the flail separates grain from straw, so the violence of suffering reveals the true character of the sufferer. The wicked blaspheme under affliction, while the righteous pray and give thanks. The difference lies not in what is suffered but in the soul of the one who suffers.
