The city of God , a philosophical treatise affirming Christianity by the medieval philosopher Saint Augustine as De civitate Dei at 413-426 ce. The city of God a masterpiece of Western culture, was written in response to pagan claims that the sack of Rome by barbarians in 410 was one of the consequences of the abolition of pagan worship by Christian emperors. Saint Augustine replied by claiming the opposite, that Christianity saved the city from total destruction and that the fall of Rome was the result of internal moralitydisintegrate. He further outlined his vision of two societies, that of the elect ("The City of God") and that of the damned ("The City of Man"). These "cities" are symbolic embodiments of the two spiritual forces - faith and unbelief - that have fought with each other since the fall of the angels. They are inextricably linked on this earth and will remain so until the end of time. Saint Augustine also developed his theological interpretation of human history, which he perceives as linear and predestined, beginning with creation and ending with the second coming of Christ.
