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.
Augustine initiates his comprehensive refutation of pagan theology by interrogating the standard explanations for Troy’s destruction. The pagan apologists claim their gods abandoned Troy because of moral outrages committed by its inhabitants, yet Augustine demonstrates that this defense collapses under scrutiny. The first charge concerns Laomedon’s alleged fraud against Apollo and Neptune, who were said to have labored as mortal workmen building the city’s walls only to be cheated of their wages. Augustine finds this narrative preposterous on multiple grounds. If these deities possessed genuine divine foreknowledge, they would have anticipated Laomedon’s treachery before undertaking the work. That they could be deceived by a mortal king reveals either profound ignorance or profound impotence—neither attribute befitting a god worthy of worship. The pagan poets themselves cannot maintain consistency in this tale, for Homer depicts Neptune as Troy’s enemy while showing Apollo as its defender, though both supposedly suffered the same injury. This internal contradiction exposes the unreliable nature of these sacred narratives. Augustine presses the logical conclusion: it is more disgraceful to venerate deities capable of being swindled than to condemn the swindler himself.
The second justification for Troy’s fall—the gods’ indignation at Paris’s abduction of Helen—receives equally withering treatment. Augustine confronts his opponents with an inescapable dilemma. If the myths about divine parentage are true, then Venus committed adultery with Anchises to produce Aeneas, and Mars violated the Vestal Rhea Sylvia to father Romulus. How can the gods punish in mortals what they themselves practice without shame? The divine perpetrators of such acts have no standing to avenge similar transgressions in human beings. If, conversely, these stories are false, then the gods cannot legitimately claim offense at real adulteries while delighting in fictional ones attributed to themselves. Augustine sharpens this point by noting that Rhea Sylvia’s seduction constituted a particularly grave sacrilege, for as a Vestal she was consecrated to divine service. The Romans themselves punished such violations in their priestesses with death by live burial. Yet Mars faced no consequences, and Rome flourished under his son’s founding. The gods’ selective indignation—destroying an entire civilization for Paris’s crime while blessing Rome despite Romulus’s far more serious offenses—reveals their moral bankruptcy.
Augustine reinforces this argument by citing Varro, the preeminent Roman antiquarian, who acknowledged that genealogical myths connecting noble families to divine ancestors were deliberate fabrications designed to inspire civic courage. This admission, coming from paganism’s own scholarly authority, devastates the claim that these religious traditions preserve truth. If useful lies form the foundation of state religion, then the entire edifice rests on deception rather than revelation. The door stands open to endless falsification in matters of worship, and the gods themselves become instruments of political manipulation rather than objects of genuine piety.
