City of God

‘City of God’ is an extensive theological book, written in the early fifth century by Augustine of Hippo, the man who would go on to become a Doctor of the Church, offered a persuasive defense of Christianity at a time when it was being blamed for the horrific sack of Rome that had happened only a few years before. It describes a kind of citizenship that transcends the material, political, and egotistical, emphasizing a community of pious, God-centered, and grace-seeking people.
In assessing history through a sharply defined lens of good and evil, Augustine was effectively interpreting human behavior in light of eternity. He examines Greek philosophers such as Plato, the Bible, and paganism in addition to drawing striking comparisons between earthly and heavenly cities. This book is regarded as a founding work of Christianity and is still a potent Christian classic today, just as it inspired the people of the author's own time.

Early church father and philosopher Saint Augustine served from 396 as the bishop of Hippo in present-day Algeria and through such writings as the autobiographical Confessions in 397 and the voluminous City of God from 413 to 426 profoundly influenced Christianity, argued against Manichaeism and Donatism, and helped to establish the doctrine of original sin. An Augustinian follows the principles and doctrines of Saint Augustine.
People also know Aurelius Augustinus in English of Regius (Annaba). From the Africa province of the Roman Empire, people generally consider this Latin theologian of the greatest thinkers of all times. He very developed the west. According to Jerome, a contemporary, Augustine renewed "The Ancient Faith."
The Neo-Platonism of Plotinus afterward heavily weighed his years. After conversion and his baptism in 387, Augustine developed his own approach to theology and accommodated a variety of methods and different perspectives. He believed in the indispensable grace to human freedom and framed the concept of just war. When the Western Roman Empire started to disintegrate from the material earth, Augustine developed the concept of the distinct Catholic spirituality in a book of the same name. He thought the medieval worldview. Augustine closely identified with the community that worshiped the Trinity. The Catholics and the Anglican communion revere this preeminent doctor. Many Protestants, especially Calvinists, consider his due teaching on salvation and divine grace of the theology of the Reformation. The Eastern Orthodox also consider him. He carries the additional title of blessed. The Orthodox call him "Blessed Augustine" or "Saint Augustine the Blessed."
