The Feast of St. Leo the Great is November 10
“Little is known about the early life of this man who proved to be such an extraordinary shepherd of the Catholic Church that he came to be known not only as Pope Saint Leo I, but also is one of the only two Popes in two thousand years to be called “the Great.” What we do know is that as a deacon of the Roman Church, before being elevated to the office of Pope in 440 AD, St. Leo the Great had opposed the heresy of Pelagianism which taught that grace was not necessary for salvation, but was rather a bonus that God granted to those who earned it by their good works. As Pope, St. Leo the Great was forceful and unambiguous in his Christological teaching which affirmed the full divinity and humanity of Christ. In fact his most famous writing, commonly known as the Tome of St. Leo (449), was the basis of the Council of Chalcedon's (451) dogmatic definition of Christ as one Divine Person possessing two complete natures, human and divine.
During his pontificate the Council of Chalcedon was convened. It condemned many popular heresies of the day, and declared that the two natures of Jesus were indivisible. Pope Leo had already defended this doctrine in the epistle called the Tome. When the Council Fathers read it they declared, “This we all believe. Peter has spoken through Leo.”
St. Leo the Great was Pope during the middle of the fifth century, a troubled time when barbarian armies were ravaging the once mighty Roman Empire. For all intents and purposes, the Western Empire was in total political and military collapse and there was a vacuum of political leadership. Pope St. Leo filled the void and became the advocate for the temporal as well as spiritual needs of his flock. He is perhaps most famous for persuading Attila the Hun to abandon his plans to sack the city of Rome and to withdraw his forces beyond the Danube river (452). St. Leo once again was the spokesperson for the Roman citizenry in 455 when the Vandal barbarians swept into Central Italy, securing concessions from them.
Through both his powerful teaching and his leadership, Pope St. Leo the Great very much strengthened the office of the Papacy and made a strong biblical case for the Divine institution of this ministry by examining the biblical evidence for Peter's unique role among the apostles.”

A thought from Pope St. Leo the Great:
“Our Redeemer's visible presence has passed into the sacraments”
A simple prayer for St. Leo's intercession:
“Oh God, You established Your Church on the solid rock of Saint Peter and You will never allow the powers of Hell to dominate her, grant that she may persevere in Your truth and enjoy continual peace through the intercession of Pope St Leo the Great.”
