St. Augustine wrote City of God in the early 400s CE, shortly after the city of Rome was sacked by a foreign tribe. Pagan critics blamed the fall on the Roman Empire’s shift to Christianity, claiming the old pagan gods had abandoned the city. Augustine’s work directly counters this claim, reframing Rome’s collapse as a minor event in the larger story of human salvation. Use this context to answer discussion questions about the text’s purpose before class.
Augustine divides all human life into two opposing communities, or “cities.” The earthly city is defined by devotion to self, material gain, and temporal power. The heavenly city is defined by devotion to God, spiritual growth, and eternal salvation. The two cities coexist throughout human history, and individuals choose their alignment through their actions and beliefs. List 3 personal choices that would align with each city in your study notes.
Augustine rejects the idea that Christianity caused Rome’s fall by pointing out that pagan empires fell long before the faith existed. He argues that Rome’s success was due to its military and political power, not divine favor from pagan gods. The text also claims that earthly empires are inherently temporary, so their collapse is not a sign of divine anger. Write a 3-sentence counterargument to one of these claims for a class debate.
The text’s central focus is on salvation, not political theory. Augustine argues that true happiness and fulfillment can only be found in the heavenly city, not in earthly success or power. He warns against attaching too much value to temporal things, as they will eventually pass. Highlight 1 line from the text (as discussed in class) that practical illustrates this core theological claim.
Augustine’s framework can be applied to modern debates about political power, consumerism, and moral values. For example, debates about wealth inequality or the role of religion in politics can be framed through the tension between earthly and heavenly priorities. Brainstorm 1 modern issue that aligns with this framework and write a 1-sentence analysis for your essay.

It is both. Augustine uses political events (like Rome’s fall) to defend religious values, so the text blends theological argument and political commentary. Focus on how the two intersect for exam answers.
City of God is a lengthy work, divided into 22 books. Most student editions use abridged versions, so check your class syllabus to confirm which books you are responsible for studying.
The main point is that spiritual salvation and devotion to God are more important than earthly power, success, or empire. Augustine also defends Christianity against claims it caused Rome’s collapse.
