St. Irenaeus Explained: Scripture, Tradition & the Magisterium

About this sermon

Who was St. Irenaeus of Lyons, and why is he one of the most important Fathers of the early Church? In this sermon, we explore the life of St. Irenaeus, disciple of St. Polycarp, who himself was taught by St. John the Apostle. As one of the Apostolic Fathers, St. Irenaeus serves as a direct witness to the faith handed down from Christ through the Apostles. Learn how he defended the Church against Gnosticism and heresy, explained the harmony of Sacred Scripture, Sacred Tradition, and the Magisterium, and preserved the Deposit of Faith that Catholics continue to profess today. His masterpiece, Against Heresies (Adversus Haereses), remains one of the strongest testimonies to the continuity and authority of the Catholic Church. This homily also reflects on the Church's need for faithful bishops, holy priests, and steadfast Catholics who remain firm in the truth amid confusion and error. "The faith once delivered to the saints remains unchanged—guarded faithfully by the Church Christ founded." 0:00 Introduction & Feast of St. Irenaeus 0:27 The Apostolic Fathers explained 1:18 Learning directly from those taught by St. John 2:01 The Deposit of Faith closes with St. John 2:36 St. Irenaeus becomes Bishop of Lyons 3:15 Battling Gnosticism and pagan errors 3:55 Scripture, Tradition & the Magisterium 5:02 Why Protestants challenged St. Irenaeus' writings 5:42 Firmness in truth vs. rigid legalism 6:33 The Quartodeciman controversy 7:43 Against Heresies and Catholic Tradition 8:15 Lessons for today's Church 8:53 Final encouragement and blessing Please remember to say 3 Hail Marys for the priest 🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴 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.
