The City of God (Volume I and II) Complete by Bishop of Hippo Saint Augustine - On the city of God against the pagans (Latin: De civitate Dei contra paganos), often called The City of God, is a book of Christian philosophy written in Latin by Augustine of Hippo in the early 5th century AD.The book was in response to allegations that Christianity brought about the decline of Rome and is considered one of Augustine's most important works, standing alongside The Confessions, The Enchiridion, On Christian Doctrine, and On the Trinity. As a work of one of the most influential Church Fathers, The City of God is a cornerstone of Western thought, expounding on many profound questions of theology, such as the suffering of the righteous, the existence of evil, the conflict between free will and divine omniscience, and the doctrine of original sin.The sack of Rome by the Visigoths in 410 left Romans in a deep state of shock, and many Romans saw it as punishment for abandoning traditional Roman religion in favor of Christianity. In response to these accusations, and in order to console Christians, Augustine wrote The City of God as an argument for the truth of Christianity over competing religions and philosophies. He argues that Christianity was not responsible for the Sack of Rome but instead responsible for Rome's success.Even if the earthly rule of the Empire was imperiled, it was the City of God that would ultimately triumph. Augustine's focus was Heaven, a theme of many Christian works of Late Antiquity. Despite Christianity's designation as the official religion of the Empire, Augustine declared its message to be spiritual rather than political. Christianity, he argued, should be concerned with the mystical, heavenly city, the New Jerusalem, rather than with earthly politics.
