St. Leo the Great (ca. 391 – November 10, 461) helped identify Christ as One Divine person with two complete natures, human and divine. One of his letters, Leo’s Tome, was strongly influential at the Council of Chalcedon in 451. He also met Attila the Hun in 452 and helped ward off his invasion of Italy. And he officially became recognized as a Doctor of the Church in 1754. The Church is truly indebted to this servant of God.
This is listed as Sermon 1 and was preached on the day of Ordination. This is very much a prayer and an encouragement to the church to pray.
Let my mouth speak the praise of the Lord, and my breath and spirit, my flesh and tongue bless His holy Name. For it is a sign, not of a modest, but an ungrateful mind, to keep silence on the kindnesses of God: and it is very meet to begin our duty as consecrated pontiff with the sacrifices of the Lord’s praise. Because in our humility the Lord has been mindful of us and has blessed us: because He alone has done great wonders for me, so that your holy affection for me reckoned me present, though my long journey had forced me to be absent. Therefore I give and always shall give thanks to our God for all the things with which He has recompensed me. Your favorable opinion also I acknowledge publicly, paying you the thanks I owe, and thus showing that I understand how much respect, love and fidelity your affectionate zeal could expend on me who long with a shepherd’s anxiety for the safety of your souls, who have passed so conscientious a judgment on me, with absolutely no deserts of mine to guide you.
I entreat you, therefore, by the mercies of the Lord, aid with your prayers him whom you have sought out by your solicitations that both the Spirit of grace may abide in me and that your judgment may not change. May He who inspired you with such unanimity of purpose, vouch safe to us all in common the blessing of peace: so that all the days of my life being ready for the service of Almighty God, and for my duties towards you, I may with confidence entreat the Lord: Holy Father, keep in Your name those whom You have given me (John 17:11): and while you ever go on unto salvation, may my soul magnify the Lord (Luke 1:46), and in the retribution of the judgment to come may the account of my priesthood so be rendered to the just Judge that through your good deeds you may be my joy and my crown, who by your good will have given an earnest testimony to me in this present life.
By the grace of God, may our Church leaders have this heart of humility and may we pray this way for the them.
