J.M.J. Absolutely! The Church is the Bride of Christ whose head on earth--the Sovereign Pontiff--and the Bishops in union with him have the charism, which includes the authority, to teach in the Name of Christ.
We have every confidence that what the Magisterium of the Church teaches about Our Lady is true.
May we learn more about the sinless Mother of God daily.
Most Sacred Heart of Jesus, have mercy on us.
Sorrowful and Immaculate Heart of Mary, pray for us.
Saint Joseph, pray for us.
