Why Marian Doctrine Matters

In this sermon Father discusses the Catholic doctrine that the Blessed Virgin Mary is rightly called Co-Redemptrix and Mediatrix of all Graces, that these titles belong to the deposit of faith and are consistently taught by Scripture, Tradition, the Fathers, Doctors, Saints, and Popes. Denying these Marian titles undermines authentic Christology, rejects the Church’s historical teaching authority, and results in doctrinal collapse masked by false ecumenism. We need unwavering devotion to Our Lady, especially in the present age of crisis, presenting her as God’s chosen instrument for the final victory over error and the salvation of souls.

Key quotes from this sermon:

• St. Louis de Montfort: “God wishes to make Mary better known in the latter times.”
• St. Alphonse Liguori: “If you call on Our Lady promptly in temptation, it is an infallible sign that you will not fall.”
• St. Maximilian Kolbe: “Mary is Co-Redemptrix because she is the Immaculate Conception, uniquely united to the Holy Ghost.”
• St. Vincent of Lérins: “We must hold what has been believed everywhere, always, and by all.”
• St. Jerome: “The whole world groaned and was astonished to find itself Arian.”
• St. John Eudes: “All the Fathers of the Church clearly teach that Mary is Co-Redemptrix with Christ in the work of salvation.”
