Saint Augustinus of Hippo

Born in Thagaste (modern Souk Ahras, Algeria) to a Christian mother (Monica) and a pagan father (Patricius), Augustine was raised in a Romanized Berber family. After schooling in Madaurus and Carthage, where he embraced Manichaeism, he pursued rhetoric in Rome and Milan. Under the influence of Bishop Ambrose of Milan and his mother’s prayers, Augustine converted to Christianity in 386 and was baptized in 387. Returning to North Africa, he founded a small monastic community before being ordained a priest in 391 and appointed coadjutor bishop of Hippo in 395 (in present-day Annaba, Algeria). Over the next three decades, Augustine became the foremost Latin theologian of his age. He authored foundational works, Confessions (an autobiographical exploration of grace and conversion), The City of God (a vision of Christian hope after Rome’s sack), and On Christian Doctrine (a guide to interpreting Scripture). His teachings on original sin, divine grace, just war, and the Trinity reshaped Western theology. Augustine died during the Vandal siege of Hippo on August 28, 430, and was later canonized as a saint and declared a Doctor of the Church.

• Bishop of Hippo: Served from 395 until his death in 430, overseeing a diocese in Roman North Africa.
• Key Works: Wrote over 100 treatises, including Confessions, The City of God, and On the Trinity, which remain central to Christian theology.
• Formulated Doctrine of Original Sin: Taught that all humans inherit a wounded nature from Adam and Eve, making divine grace essential for salvation.
• Father of Western Theology: Alongside Ambrose, Jerome and Gregory the Great, Augustine is regarded as one of the “Great Latin Fathers.”
• Influence on the Reformation: Martin Luther, John Calvin and other Protestant Reformers drew heavily on Augustine’s teachings about grace, election, and faith.
