The City of God by Augustine

Augustine divides his discussion of Rome's failings into two parts. One dealing with earthly concerns, like sacking of cities, the other with more fundamental questions of virtue and vice. This mirrors another contrast that gives the work its name, the contrast between the city of man and the city of God. Augustine traces these two cities back to the dawn of man,. The pride characteristic of the earthly city began with the fallen angels while the good angels are most outstanding citizens of the eternal city.
