Of the different controversies that preoccupied Augustine during his lifetime, Pelagianism was indisputably the most important for the subsequent history and theology of the western Church. It touched on any number of issues central to Christianity, most notably grace, predestination, original sin and baptism, all of which in turn could be reduced to the fundamental question of the exact nature of the relationship between God and his human creation. The six major treatises presented in this volume amply illustrate Augustine's struggle with the theological problems that Pelagianism raised. They begin with the Miscellany of Questions in Response to Simplician. Although written in 396, before Pelagianism even appeared on the scene, this work shows in a few pages the remarkable evolution of Augustine's thought on the matter of grace and the position at which he arrived and to which he clung for the rest of his life. The two final treatises, The Predestination of the Saints and The Gift of Perseverance, written in 428/429 shortly before Augustine's death, indicate where the position that he had elaborated more than thirty years before was fatefully destined to take him. The three middle treatises show Augustine in the process of refining -- but not altering -- his thinking in the face of what he rightly saw as Pelagianism's terrible threat to orthodox Christianity's central tenets.
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."
I have not read this entire volume, but selections only. This debate is important in the life of the Church, but is far more nuanced than the average online Christian seems to understand. Augustine is of course a Father of the Church and a Doctor, but even he goes astray here and there.
