The confessions of Saint Augustine -- The imitation of Christ / Thomas à Kempis -- Pilgrim's progress / John Bunyan.
Saint Augustine was a towering Christian leader and one of the great fathers of the Church. His Confessions is a timeless work, revealing the joys and agonies of a life lived in search of truth.
Few books have been read more assiduously during the last five centuries than The Imitation of Christ, Thomas à Kempis' meditation on humility. As it spans the centuries, it crosses all ecclesiastical divisions and speaks to the "princes" of the Church as it speaks to the common man.
In the 300 years since John Bunyan's death, Pilgrim's Progress has been an inspiration to countless readers. It tells the tale of Christian and his journey from the City of Destruction to the Celestial City. The joy, sorrow, temptation, and danger he encounters on the way are as instructive today as when the book was first written.
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."
