The Woman, the Serpent, and the Triumph of the Immaculate Heart

1 hour 3 minutes

In this sermon Father discusses the divine motherhood of the Blessed Virgin Mary as the foundation of all Marian doctrine and as inseparable from authentic Christology and the Catholic Faith. Attacks on Mary’s titles — especially Mother of God, Mediatrix of all Graces, and Co-Redemptrix — are signs of doctrinal collapse foretold by saints, councils, and Marian apparitions. Heresy against Mary inevitably leads to heresy against Christ; we need to remain steadfast, to defend revealed dogma even amid ecclesial confusion, and to deepen devotion to Our Lady — particularly through the Rosary — as a sign of fidelity and perseverance unto salvation.

Key quotes from this sermon:

St. Louis de Montfort: “Whoever wishes to possess Jesus must possess Mary.”

St. Alphonse Liguori: “One good priest leads thousands to heaven; one bad priest leads thousands to hell.”

St. Louis de Montfort: “Jesus is the fruit of Mary, and Mary is the true tree of life.”

St. Justin Martyr: “The Virgin Mary became the cause of salvation for herself and for the whole human race.”

St. Irenaeus of Lyons: “The knot of Eve’s disobedience was loosed by the obedience of Mary.”

St. Augustine: “The elect are carried in the womb of Mary until she brings them forth into eternal glory.”

St. Catherine of Siena: “This vice [sodomy] is so abominable that even the demons turn away in horror.”
