Possibly one of the greatest and well-known of Medieval theological Philosophers and Writers, Augustine was born in Numidia (Africa), in the year 354 A.D. Growing up in the waning days of Rome, Augustine's father was a Pagan (Roman Officer) and his Mother was a devout Christian. Growing up in this paradox seemed to suit Augustine. Giving him a quick intellect and a studious manner, his parents sent him to Carthage for studies. Taught Philosophy by reading Cicero – Augustine for a very brief period of time was a Dualist.
In adulthood, Augustine went to Milan, Italy and met Ambrose. Their discussions (often lasting days) turned Augustine's way of thinking into the more traditionalist theology pattern he is known for. Having a “mystic vision”, Augustine was baptized and converted to “true” Christianity (down by Ambrose). Entering into The Church, Augustine quickly became Bishop of Hippo (Tunis). Continuing with his theological writings around this time (396 A.D.), Augustine wrote his 2 best known (and still read) books on Christianity. “Confessions” and “City of God” are still required reading in many theological Seminaries and even non-Christian Colleges and Universities.
Dealing with Man's Faith and the Ideals of God, Augustine showed the simple formula for Man's redemption and entrance into Heaven. His concepts were extremely revolutionary for his day (and indeed reshaped Medieval Philosophy). Constantly attacked by rising Heretical Groups around every corner of Hippo, Augustine never backed away from a “discussion” - and he never lost one either. Other later Medieval Philosophical “Thinkers” such as Thomas Aquinas and Bernard of Clairvaux were greatly influenced by Augustine. Augustine died in Hippo in the year 430 A.D. Canonized (Sainted), Augustine is also one of only 33 Doctors of The Catholic Church, for his Theological writings and advancements.
