Which church father is famous for writing The City of God?

• A. Jerome
• B. Augustine
• C. Origen
• D. Athanasius

Answer: (B)

The main concept tested here is identifying the author and the significance of The City of God in Christian thought. The City of God is Augustine’s major work, written after Rome’s sack in 410 CE while he was bishop of Hippo in North Africa. In it, he contrasts two cities—the earthly city and the City of God—and uses that framework to explain why Christians endure suffering and how faith relates to secular power. Augustine also defends Christianity against the claim that it caused Rome’s downfall, while showing how Christian doctrine can harmonize with classical philosophy. This work helped shape medieval political theology and the Western understanding of history, making Augustine the author most closely associated with it. Jerome is known for translating the Bible into Latin (the Vulgate) and other biblical scholarship; Origen was an early theologian who explored allegorical interpretation and systematic theology; Athanasius defended Nicene orthodoxy and wrote on faith and monastic life—none wrote The City of God.
