Intercede for us that we may remain steadfast in truth, courageous in trials, and wise in guiding others toward Christ. Pray that our words and actions may always reflect the love and clarity of the Gospel. Amen.

St. Leo the Great was born in the late 4th century and became pope in 440 during a time of great turmoil in the Church and the Roman Empire. Known for his wisdom, courage, and clarity of teaching, Leo worked tirelessly to defend the true faith. He confronted heresies that threatened the unity of the Church, most notably affirming the two natures of Christ—both fully God and fully man—at the Council of Chalcedon. His preaching and letters helped shape Catholic doctrine for centuries to come. Beyond his theological contributions, Leo also displayed remarkable bravery, famously meeting Attila the Hun and persuading him to turn back from invading Rome. He died in 461 and was declared a Doctor of the Church, remembered for his pastoral care, strong leadership, and eloquence in defending the truth.
