Augustine began City of God De Civitate Dei to answer complaints that Christians were to blame for the troubles of Rome and its empire because they would not sacrifice to the gods. In August 411 Alaric the Goth led barbarian warriors into the city. Refugees crossed to Africa Augustine s homeland where he was bishop of Hippo. This English-language commentary discusses Books 1-5 in which Augustine argued that Rome suffered worse disasters before Christianity was known; that empire depends on injustice; and that everything depends on the will of the true God not on the many gods of Roman tradition. He had taught classical Latin literature and rhetoric and used material and techniques which were familiar to educated Romans. He exploited authors they found authoritative: Sallust on Roman history Cicero on Roman government Virgil on Rome s imperial mission the scholar Varro on Roman religious tradition. He discussed power and glory pleasure and virtue; war and suicide rape and celibacy; the purpose of suffering; fate and choice. He made a commitment to debate with philosophers on worshipping many gods for the sake of life after death and to move from refuting false beliefs to expounding Christian teachings on the two cities . The earthly city is the community of all who love themselves rather than God; the city of God is the community of all who love God rather than themselves. City of God took 22 books which were influential--and often misunderstood--in later centuries.
