Leo I, Pope and Doctor of the Church, ruled from 440 to 461. He is surnamed "the Great" and ranks among the most illustrious sovereigns that ever sat on the throne of St. Peter. Of his life, we know little; with him the man seems to disappear before the Pope. He saw most clearly that one of his greatest tasks was to vindicate the primacy of the Roman bishop, St. Peter's successor, and to raise the prestige of the Holy See before the entire world. Hardly any Pope in history has occupied a like position in the ecclesiastical and political world. 
As a young priest Andrew served at an ecclesiastical court. While making a defense, a small lie slipped by his lips; soon afterward he accidentally read the words, "A lying mouth kills the soul" (Wis. 1:11). Deeply moved, he resigned his position and dedicated himself solely to the service of God and the welfare of souls. In 1566 he entered the Order of Theatines and chose the name Andrew out of love for the Cross of Christ. He labored most zealously as a shepherd of souls. With fatherly love and prudence he spent countless hours hearing confessions. He frequently visited the towns and villages in the neighborhood of Naples to preach the saving message of the Gospel.
St. Tryphon, whose relics were preserved at Cattaro, in Dalmatia, had an oratory at Rome in which the Greeks celebrated his feast on February 1. For unknown reasons hagiographers have joined his commemoration with that of St. Respicius, who appears to have been a Roman martyr. St. Nympha was venerated at Porto in Sicily; her body, translated to Rome, was buried in the church of SS. Tryphon and Respicius. Due to lack of evidence this feast was removed from the General Roman Calendar in 1969.

Profile
Born to the Italian nobility. Strong student, especially in scripture and theology. Priest. Eloquent writer and homilist.
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.

Peter has spoken by the mouth of Leo. – Council of Chalcedon
Virtue is nothing without the trial of temptation, for there is no conflict without an enemy, no victory without strife. – Pope Saint Leo the Great
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
