- Leo I
Pope from 440 to 461 during the time of the invasion of Attila the Hun. When Attila marched on Rome, Leo went out to meet him and pleaded for him to leave. As Leo spoke, Attila saw the vision of a man in priestly robes, carrying a bare sword, and threatening to kill the invader if he did not obey Leo; Attila left. As Leo had a great devotion to Saint Peter the Apostle, it is generally believed the first pope was the visionary opponent to the Huns. When Genseric invaded Rome, Leo’s sanctity and eloquence saved the city again.
Called the Council of Chalcedon to condemn heresies of the day. Fought Nestorianism, Monophysitism, Manichaeism, and Pelagianism. Built churches. Wrote letters and sermons encouraging and teaching his flock, many of which survive today; it is for these writings that Leo was proclaimed a Doctor of the Church in 1574.

Although the universal Church of God is constituted of distinct orders of members, still, in spite of the many parts of its holy body, the Church subsists as an integral whole, just as the Apostle says: “We are all one in Christ,” nor is anyone separated from the office of another in such a way that a lower group has no connection with the head. In the unity of faith and baptism, our community is then undivided. There is a common dignity as the apostle Peter says in these words: “And you are built up as living stones into spiritual houses, a holy priesthood, offering spiritual sacrifices which are acceptable to God through Jesus Christ.” And again: “But you are a chosen people, a royal priesthood, a holy nation, a people of election.” For all, regenerated in Christ, as made kings by the sign of the cross. They are consecrated priests by the oil of the Holy Spirit, so that beyond the special service of our ministry as priests, all spiritual and mature Christians know that they are a royal race and are sharers in the office of the priesthood. For what is more king-like than to find yourself ruler over your body after having surrendered your soul to God? And what is more priestly than to promise the Lord a pure conscience and to offer him in love unblemished victims on the altar of one’s heart? - from a sermon by Pope Saint Leo the Great
God decreed that all nations should be saved in Christ. Dear friends, now that we have received instruction in this revelation of God‘s grace, let us celebrate with spiritual joy the day of our first harvesting, of the first calling of the Gentiles. Let us give thanks to the merciful God, “who has made us worthy,” in the words of the Apostle, “to share the position of the saints in light; who has rescued us from the power of darkness, and brought us into the kingdom of this beloved Son.” This came to be fulfilled, as we know, from the time when the star beckoned the three wise men out of their distant country and led them to recognize and adore the King of heaven and earth. The obedience of the star calls us to imitate its humble service: to be servants, as best we can, of the grace that invites all men to find Christ. - from a sermon by Pope Saint Leo the Great
