St. Cyril of Alexandria: Against Nestorianism, and Why Mary Is the Mother of God (9 February)

About this sermon

As we approach Lent, spiritual reading and serious theology matter more than ever. In this talk, we reflect on St. Cyril of Alexandria, Bishop and Doctor of the Church, and his decisive role at the Council of Ephesus (431 AD) in defending the truth about Our Lord Jesus Christ against the heresy of Nestorianism. Nestorius claimed that God could not die, and therefore Christ must be two persons—one human and one divine. St. Cyril exposed this fatal error by clarifying the Church’s teaching: 👉 Christ is ONE divine Person with TWO natures—human and divine. Because there is only one Person, everything Christ does is done by God the Son—whether He eats, suffers, or dies on the Cross. This is why the Church infallibly teaches that Mary is truly the Mother of God (Theotokos). If God did not die on the Cross, then our redemption collapses. Theology is not abstract—it is the foundation of the Faith. This teaching remains crucial today, especially when explaining the Faith to Protestant friends and family, many of whom deny the title Mother of God without realizing the Christological consequences. 📖 This video also encourages Lenten spiritual reading, including: St. Alphonsus Liguori St. Cyril of Alexandria Fr.
