The Spiritual War of Saint Augustine
St. Augustine in his book Confessions develops his narrative talent by developing his personal story in the first person in the character of confession to God, that is, he confesses in the book before God for his life, his personal itinerary. In the thought of San Agustin, the effort of synthesis between Greek philosophy and the Christian religion is clearly seen.
Remember that Christianity is an Eastern religion, Christ speaks about the "spirit", the light, the salvation and the spiritual rebirth. St. Augustine is a teacher of Rhetoric, from there he takes Plato's teachings about the world of the ideas and from Aristotle's the soul, the virtue and the friendship, which St. Augustine develops in his book. From Christianity takes the ideas of beatitudes and the concept of mercy and providence that everything rules.
From this synthesis or mixture a new philosophy is born: the scholastic philosophy.
San Agustin studied grammar and rhetoric since childhood, a very profitable profession in those days, comments in his book about the loss of his father and the devotion of his mother for the Christian faith, which supported him in his studies. As professor of Rhetoric in Cartago he knows the classics, he studies astrology and the Manichean and Apollinarian heresies (Book VII, C XIX).
But he recognizes that reason and study do not allow him to elucidate the truth and the wisdom that he tries to find, he bitterly recognizes as reflection: "In the Piety is the Wisdom" Book V, Cap V, Augustine translates the Fear of God as Piety from the Book of Job.
St. Augustine is marked, he himself recognizes (Book VIII, C 2) by the books of Plato and in his studies reasons that by the sinful nature of man and by love of the worldly things, we are deprived of grace and we can not access to the ultimate mysteries, that is, the Truth, the wisdom, by the use of reason as the Greek classics maintained, we need something more. And it is here where we enter in the field of Christianity.
For Saint Augustine, the access to the good and the truth: "Charity has spread in our hearts through the Holy Spirit" (L XIII, C VII), through his experience of conversion, is with the devotion (Piety) to God like in Romans 5:5.
