Augustine of Hippo’s The City of God is generally considered to be one of the key works of Late Antiquity. Written in response to allegations that Christianity had brought about the decline of Rome, Augustine here explores themes in history, political science, and Christian theology, and argues for the truth of Christianity over competing religions and philosophies. This Companion volume includes specially-commissioned essays by an international team of scholars that provide new insights into The City of God. Offering commentary on each of this massive work’s 22 books chapters, they sequentially and systematically explore The City of God as a whole. Collectively, these essays demonstrate the development and coherence of Augustine’s argument. The volume will be an invaluable resource for students and scholars of ancient and contemporary theology, philosophy, cultural studies, and political theory.
