St. Januarius (19 September) - This Saint’s Blood Liquefies Every Year… And Science Can’t Explain It

About this sermon

Why does the preserved blood of St. Januarius repeatedly liquefy—and what might this ancient phenomenon reveal about faith, miracles, and conversion? St. Januarius was an Italian bishop martyred with his companions during the persecution of Diocletian around A.D. 305. According to tradition, he ministered courageously to imprisoned Christians before being captured and condemned. Some accounts say wild beasts refused to attack the martyrs; ultimately, Januarius and his companions were beheaded. His relics remain at the center of one of Catholicism’s most famous recurring phenomena. Preserved blood associated with the martyr is publicly displayed in Naples, where its solid contents have repeatedly liquefied during prayer and liturgical celebrations. The event has become both a religious observance and an important civic tradition. The homily explores the miracle’s traditional symbolism: the reunion of blood and body anticipates the resurrection of the dead. It also considers why supernatural signs do not compel belief. God provides indications that invite sincere investigation, humility, prayer, meditation, and a deeper search through Scripture and theology. Arguments alone rarely convert souls. Conversion requires grace, persistent prayer, and charity capable of suffering for another person’s salvation. The crucifix is the supreme proof of such love. St. Januarius, pray that we may possess the faith and charity necessary to suffer well and help lead souls to Christ. 00:00 Opening prayer 00:14 St. Januarius and the Diocletian persecution 00:32 The mysterious liquefaction of his blood 00:39 His early life and priestly vocation 01:12 Consecrated a bishop while still young 01:37 Ministering during severe persecution 02:01 Arrest and imprisonment 02:09 Condemned to the wild beasts 02:41 Different accounts of the miracle and martyrdom 03:03 Beheaded with his companions 03:12 The preserved blood of St. Januarius 03:31 The blood liquefies on his feast 03:46 Relics reunited and the resurrection of the body 04:19 How the phenomenon changed over time 04:34 Can modern science explain it? 04:50 Where the blood and relics are preserved 05:26 The procession and public ceremony in Naples 06:08 The civic celebration after liquefaction 06:31 Occasions when the blood does not liquefy 06:49 Popes and the blood of St. Januarius 07:20 Miracles invite investigation and meditation 07:50 Why doesn’t God make Himself more obvious? 08:28 God reveals Himself throughout creation 09:00 Knowing Christ through Scripture 09:15 Evidence as an invitation to seek God 09:32 Why some people reject evidence 10:36 The modern world does not want to believe 10:44 Scientific questions surrounding the blood 11:16 Prayer is essential for conversion 11:32 “They will know we are Christians by our love” 11:41 Suffering as the proof of love 11:57 Prayer for faith, charity and perseverance 12:14 Final blessing https://sensusfidelium.us/the-liturgical-year-dom-prosper-gueranger/september/september-19-st-januarius-bishop-and-his-companions-martyrs/ Please remember to say 3 Hail Marys for the priest #SaintJanuarius #SanGennaro #CatholicFaith #CatholicSaints #CatholicChurch #CatholicMiracles #ChristianMartyrs #FaithAndReason #CatholicTradition #CatholicHomily 🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴 ✝️ SUPPORT THE MISSION 🙏 Donate https://sensusfidelium.com/donate-support/ 📬 Free Catholic Newsletter https://sensusfidelium.com/newsletter/ 📰 Read on Substack https://sensusfidelium.substack.com/ ──────────────────── 📺 WATCH & READ 📺 Sensus Fidelium App https://sensusfidelium.tv/ 📚 Sensus Fidelium Press https://sensusfideliumpress.com/ 👕 Official Merchandise https://sensusfidelium.com/merchandise/ ──────────────────── 🤝 PARTNER WITH US 📣 Advertise on Sensus Fidelium https://sensusfidelium.com/advertise-with-sensus-fidelium/ 🎤 Invite Steve Cunningham to Speak https://sensusfidelium.com/speaking/ ⛪ Parish Formation & Consultation https://sensusfidelium.com/for-parishes/ ──────────────────── 🌎 CATHOLIC COMMUNITY ✝️ Trusted Catholic Businesses https://sensusfidelium.com/catholic-businesses/ 🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴🔴
