Welcome to the pontificate of Pope Leo XIV, the first pope from the Order of St. Augustine (OSA), also known as the Augustinians. This ancient religious order, with thousands of members worldwide, has made history with the election of Pope Leo XIV.
The Order of St. Augustine traces its roots back nearly 800 years, originating from a union of various religious communities following the Rule of St. Augustine. This rule, written by the saint in the fourth century, remains a guiding force for Catholic orders to this day.
Discovering St. Augustine of Hippo (354–430)
St. Augustine, an early Catholic bishop, theologian, and doctor of the Church, profoundly influenced Catholic doctrine for centuries. His autobiographical work, the “Confessions,” recounts his journey from a life of worldly pursuits to a profound conversion to Christianity.
Initially raised in the Christian faith, Augustine strayed from his beliefs and indulged in worldly pleasures. However, a chance encounter with St. Ambrose, a bishop and influential figure, reignited his faith and led him back to the Catholic Church. Augustine’s conversion was a result of years of prayer by his mother, St. Monica.
Returning to Africa, Augustine was ordained as a priest and later reluctantly became the bishop of Hippo. His writings and teachings continue to inspire and shape Catholic theology, making him one of the most influential figures in Church history.
Augustine: The Pastor and Philosopher
After accepting God’s will, Augustine devoted the rest of his life to serving as a pastor in a North African town. He spent much of his time refuting the writings of heretics, solidifying his reputation as a defender of the faith.
Augustine’s literary works, such as “Confessions” and “The City of God,” have stood the test of time as classics of Christian writing and philosophy.
The Legacy of Augustine’s Rule
As bishop, Augustine led a monastic community life with his clergy, setting an example that inspired many to follow. His instructions for monastic communities, like “De opere monachorum,” provided guidance for those seeking to live a life of devotion.
The Lateran Synod in 1059 approved Augustine’s rule for canons, leading to the formation of the Hermits of St. Augustine. This mendicant order emphasized love for God and neighbor, communal living, and humility over status.
Under Pope Innocent IV and Alexander IV, the order grew rapidly, with friars engaged in various ministries around the world. From Europe to North and South America, Africa to Asia, the Augustinians spread their message far and wide.
Today, the Augustinians continue their mission with three regional provinces in the United States, carrying on the legacy of their founder in service and faith.
