St. Augustine of Hippo (354-430) was one of the most prolific geniuses that humanity has ever known, and is admired not only for the number of his works, but also for the variety of subjects, which traverse the whole realm of thought. The form in which he casts his work exercises a very powerful attraction on the reader. Bardenhewer praises his extraordinary suppleness of expression and his marvellous gift of describing interior things, of painting the various states of the soul and the facts of the spiritual world. His latinity bears the stamp of his age. In general, his style is noble and chaste; but, says the same author, "in his sermons and other popular writings he purposely drops to the language of the people." A detailed analysis is impossible here. We shall merely indicate his principal writings and the date (often approximate) of their composition.
Augustine in the "De Doctrinâ Christianâ" (begun in 397 and ended in 426) gives us a genuine treatise of exegesis, historically the first (for St. Jerome wrote rather as a controversialist). Several times he attempted a commentary on Genesis. The great work "De Genesi ad litteram" was composed from 401 to 415. The "Enarrationes in Psalmos" are a masterpiece of popular eloquence, with a swing and a warmth to them which are inimitable. On the New Testament: the "De Sermone Dei in Monte" (during his priestly ministry) is especially noteworthy; "De Consensu Evangelistarum" (Harmony of the Gospels — 400); Homilies on St. John (416), generally classed among the chief works of Augustine; the Exposition of the Epistle to the Galatians" (324), etc. The most remarkable of his Biblical works illustrate either a theory of exegesis (one generally approved) which delights in finding mystical or allegorical interpretations, or the style of preaching which is founded on that view. His strictly exegetical work is far from equalling in scientific value that of St. Jerome. His knowledge of the Biblical languages was insufficient: he read Greek with difficulty; as for Hebrew, all that we can gather from the studies of Schanz and Rottmanner is that he was familiar with Punic, a language allied to Hebrew. Moreover, the two grand qualities of his genius — ardent feeling and prodigious subtlety — carried him sway into interpretations that were violent or more ingenious than solid.
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."
