The story of their life
Augustine was born on 13 November 354 in Thagaste, a town in the Roman province of Numidia in North Africa. His father, Patricius, was initially a pagan, while his mother, Monica, was a committed Christian. Augustine was enrolled as a Christian catechumen as a child but was not baptised during his early years.
His family recognised his exceptional intellectual ability and made significant sacrifices for his education. Augustine studied grammar and literature at Madaura before continuing his training in rhetoric at Carthage. He became highly ambitious and hoped that education, eloquence and professional success would bring him fulfilment.
While still young, Augustine entered a long-term relationship with a woman whose name he never records in his surviving writings. Their son, Adeodatus, was born when Augustine was approximately eighteen. Augustine later spoke warmly of his son’s intelligence and spiritual promise.
Around this period, Augustine read Cicero’s lost work Hortensius. The book awakened in him a passionate desire for wisdom, but he found the style and apparent simplicity of the Bible disappointing. Seeking an explanation of good, evil and the material world that appeared intellectually satisfying, he became associated with Manichaeism.
Augustine remained connected to the Manichaean movement for approximately nine years. He was attracted by its claim to provide rational explanations for the conflict between good and evil, but gradually became dissatisfied with its teachers and doctrines. His search then passed through scepticism and engagement with different philosophical traditions.
He taught rhetoric in Thagaste and Carthage before travelling to Rome in 383. In 384 he obtained a prestigious position as professor of rhetoric in Milan. There he encountered St Ambrose, whose preaching showed him that Scripture could be interpreted with greater intellectual depth than Augustine had previously recognised.
Augustine’s reading of philosophical works associated with Neoplatonism helped him understand God as spiritual rather than material. The letters of St Paul confronted him more directly with Christ, grace and the moral transformation he had long postponed.
His intellectual difficulties were gradually being resolved, but he remained divided in his will. He desired a new life while still feeling attached to ambition, sexual relationships and personal control. In the summer of 386, during an intense struggle in a garden in Milan, he heard a childlike voice repeating words he understood as “take and read.” He opened the letters of St Paul and read Romans 13:13–14. He experienced this moment as the decisive surrender of his resistance to God.
Augustine withdrew with family and friends to Cassiciacum, where they prepared for baptism through prayer, conversation and philosophical reflection. During the Easter Vigil on 24 April 387, Augustine was baptised in Milan by St Ambrose together with his son Adeodatus and his friend Alypius.
Augustine then planned to return to North Africa and establish a community devoted to God. While awaiting passage at Ostia, he and Monica shared the profound spiritual conversation later described in the Confessions. Monica became ill and died shortly afterwards. Augustine’s account of her death is one of his most personal reflections on grief, faith and eternal life.
After returning to Africa, Augustine established a community at Thagaste. His son Adeodatus died while still young. Augustine subsequently travelled to Hippo, intending to recruit a possible member for the community. While attending church there in 391, he was unexpectedly chosen by the congregation and ordained a priest despite his reluctance.
As a priest, Augustine founded another religious community, preached, studied Scripture and assisted the ageing Bishop Valerius. In 395 he was ordained a bishop and subsequently became Bishop of Hippo. He remained in that ministry until his death.
Augustine’s episcopal life was demanding. He preached frequently, instructed catechumens, judged disputes, cared for people in poverty, formed clergy and religious communities, answered correspondence and participated in Church councils. His surviving sermons reveal a pastor speaking directly to ordinary Christians rather than only an academic theologian.
He also became involved in major theological and ecclesial controversies. He wrote against Manichaeism, the religion he had formerly followed. He argued extensively against the Donatist movement, which had divided North African Christianity, and later defended the necessity of divine grace against positions associated with Pelagius and his followers.
Augustine initially emphasised argument and persuasion in addressing the Donatist division but later defended the use of imperial pressure to bring separated Christians into Catholic unity. This part of his legacy is historically important and should not be presented uncritically. His support for religious coercion reflected the political and ecclesial assumptions of his time but remains morally troubling when judged in light of religious freedom and the dangers of institutional force.
Among Augustine’s best-known works is the Confessions, written as a prayer to God rather than as a modern autobiography. It recounts his memories, sins, relationships, intellectual development and conversion while reflecting on memory, desire, Scripture and the action of grace.
After the sack of Rome in 410, some critics blamed Christianity for the weakening of the Roman world. Augustine responded through The City of God, a vast work distinguishing the earthly city shaped by disordered love from the City of God formed by love of God. He argued that no political society should be confused with the final Kingdom of God.
Other major works include On the Trinity, On Christian Doctrine, the Enchiridion on Faith, Hope and Love, biblical commentaries, letters, sermons and the Rule associated with his communities. Near the end of his life, Augustine composed the Retractions, reviewing his earlier works and identifying points requiring correction or clarification. This willingness to revise himself is an important aspect of his intellectual integrity.
In 430, the Vandals placed Hippo under siege. Augustine remained with his people and other displaced clergy. During his final illness, he asked for the penitential psalms to be displayed where he could read them and spent his remaining days in prayer and repentance.
Augustine died on 28 August 430 at the age of seventy-five. His works survived the destruction that followed and became foundational for later Christian reflection on grace, freedom, desire, sin, the Church, the sacraments, Scripture, society and the human search for God.
His influence extends far beyond one school of theology. Catholic, Orthodox and Protestant traditions have all received, debated and interpreted his writings in different ways. The Church venerates him as a Father and Doctor whose central insight remains deeply personal: the human heart cannot finally rest in status, pleasure, knowledge or power, because it was created for communion with God.
