Byzantine Saints: Saint Leo the Great, Pope of Rome (18 February)

About this sermon

St. Leo the Great, Pope of Rome (440–461), stands as one of the greatest defenders of Catholic orthodoxy in Church history. Commemorated on February 18, St. Leo I boldly protected the truth of Christ’s two natures — fully God and fully man — at a time when heresy threatened to divide the Church. In this episode, we explore how St. Leo confronted the dangerous errors of Eutyches, Dioscorus, and Nestorius, and how his famous “Tome of Leo” shaped the outcome of the Fourth Ecumenical Council at Chalcedon in 451. When his letter was read before 630 bishops, they declared: “Peter has spoken through Leo.” But St. Leo was not only a theological giant — he was also a courageous shepherd. In 452, he personally met Attila the Hun and persuaded him not to destroy Rome. Later, he convinced the Vandal king Genseric to spare lives when invading the city. His legacy includes 96 sermons and 143 letters, forming one of the most important theological collections in Church history. St. Leo the Great shows us what true Catholic leadership looks like: pastoral charity combined with unshakable firmness in defending the truth. St. Leo the Great, pray for us. 0:00 Introduction 0:20 Early Life and Education 0:44 Election as Bishop of Rome (440) 0:56 Heresies Threatening the Church 1:13 The Error of Eutyches and Dioscorus 1:24 Defense Against Nestorianism 1:35 Letters to Emperor Theodosius II and Marcian 1:44 The Council of Chalcedon (451) 2:16 The Two Natures of Christ Explained 2:29 Excommunication of the Monophysites 2:35 Confronting Attila the Hun (452) 2:49 Sparing Rome from the Vandals (455) 3:03 Preparation for Death 3:11 His Legacy: Sermons and Letters https://www.oca.org/saints/lives 🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴 Support Catholic Businesses here - https://sensusfidelium.com/catholic-businesses/ Sensus Fidelium Press - https://sensusfideliumpress.com/ Sensus Fidelium Apps - https://sensusfidelium.tv/ Support Sensus Fidelium - https://sensusfidelium.com/donate-support/ 🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴 🙏🏻PLEASE HELP OUR CHANNEL GROW 🙏🏻 ▶️ 1.
