The City of God is one of the most important works of Christian history and philosophy ever written. The writings of St. Augustine are as intriguing to the casual reader as it is to Christian researchers. St. Augustine's work provides insight into Western thought and the development of Western civilizations. The City of God provides the reader with an artful contrast between earthy cities and those in heaven as a representation of the eternal struggle between good and evil. The City of God was originally penned in the early 5th century as a response to the prevalent belief that Christianity was to blame for the fall of Rome. St. Augustine is known as one of the most influential Fathers of the Catholic Church. Born November 13, 354, Augustine would eventually be recognized as a Saint by the Catholic Church, the Eastern Christian Church, and the Anglican Communion.

Chief among the apostolic fathers are the three first-century Bishops: St. Clement of Rome, St. Ignatius of Antioch, and St. Polycarp of Smyrna, who were disciples of St. Peter and St. John.

This, Lewis' last book, has been hailed as "the final memorial to the work of a great scholar and teacher and a wise and noble mind".
