Saint Augustine of Hippo is one of the most influential figures in Christian history—a man whose journey from worldly pleasures to deep faith has inspired countless believers. He went from a sinful life apart from God to a great Saint, Bishop, and eventually Doctor of the Church. Augustine, known for his high intelligence and important writings - such as Confessions, The City of God, and On the Trinity - had such a great and miraculous conversion in his life. He went from a very sinful lifestyle of partying and worldly ambitions to one of the most influential early Saints of the Catholic Church. His writings and knowledge are still highly regarded today.

Life and Conversion

Born in North Africa to a pagan father, Patricius, and a devout Christian mother, Saint Monica, Augustine was gifted with a brilliant mind but struggled to find the truth. As a young man, he pursued worldly ambitions: excelling in rhetoric, teaching, and philosophy. He also fell into a lifestyle of self-indulgence and sin, famously praying, “Lord, make me chaste… but not yet.”

He was incredibly intelligent, but was stuck in a sinful lifestyle. While he was raised as a Christian, his sins clouded his mind to the truth. At one point in his life he left Christianity and joined the Manichaean Religion, an ancient world religion that has since died out. Even when he believed that Christianity was the true religion, he still did not believe he was capable of living a pure and Christian life. He was stuck in many situations that kept him in his sin, despite his will to change.

Augustine’s spiritual restlessness led him through various philosophies and beliefs, including Manichaeism, but none brought him peace. His mother, Monica, prayed unceasingly for his conversion. The turning point came in Milan when he encountered the eloquent preaching of Saint Ambrose. Struck by Ambrose’s wisdom and the depth of Scripture, Augustine began to feel God calling him more strongly.

Augustine felt particularly called to do more in his life when he heard about 2 men who converted after reading the life of Saint Anthony the Great. He said to his friend Alipius, “What are we doing? Unlearned people are taking Heaven by force, while we, with all our knowledge, are so cowardly that we keep rolling around in the mud of our sins!"

One day, tormented by his inability to break free from sin, Augustine heard a child’s voice chanting, “Take and read.” He opened the Bible to Romans 13:13–14, which spoke of casting off darkness and living in Christ. In that moment, he surrendered fully to God—his deep and decisive conversion. In 387, Augustine was baptized by Saint Ambrose, marking the beginning of his life of holiness. He was mentored by Saint Ambrose, a very great Saint of his time.

Returning to North Africa, Augustine founded a monastic community and was later made Bishop of Hippo. As bishop, he became one of the greatest defenders of the faith, battling heresies and Manichaean, in which he was previously involved. His writings, especially Confessions and The City of God, remain pillars of Christian theology, exploring God’s grace, the nature of the Church, and the eternal destiny of humanity. They explore major theological points, and also include Augustine's conversion to Christianity once again.

Death

In the final days of his life, Augustine witnessed the siege of Hippo by the Vandals. The Vandals had invaded North Africa and besieged Hippo in spring of 430. During this time, Saint Augustine performed one of the few miracles attributed to him during his life, when he healed a sick man. Surrounded by turmoil, he spent his last days in prayer and penance. He died on August 28, 430, at the age of 75. When the Vandals eventually pillaged the city, they destroyed almost everything, but left Augustine’s cathedral and library untouched.

He was later canonized as a Saint and Doctor of the Church in 1303 and 1298, respectively.

Saint Augustine’s significance to the Church is profound. His teachings on grace, free will, and the inner life shaped Western Christianity for centuries. His own journey—from a sinner seeking worldly satisfaction to a saint consumed by God’s love—stands as a timeless testament to the transforming power of divine mercy.

Saint Augustine, pray for us!
