As you know, dear sons, it is a celebrated fact that the rosary was entrusted by the Holy Mother of God to Saint Dominic as a singular help when he battled against monstrous errors.

- Blessed Pope Pius IX

The Most Holy Rosary is the most powerful, easy, and gentle means for dispelling ignorance and for removing errors and heresies.

- Saint Anthony Mary Claret

As Saint Dominic employed the Rosary as a sword to destroy the monstrous heresy of the Albigenses, so likewise in our time the faithful, in using the same weapon - that is to say, the daily recitation of the Rosary - will obtain that, by the all-powerful protection of the Mother of God, the many errors infecting the world will be uprooted and destroyed.

- Blessed Pope Pius IX
