“…who had received it from the Blessed Virgin as a powerful means of converting the Albigensians and other sinners” (The Secret of The Rosary, St. Louis De Montfort, 18).
I guess the power of the rosary to “convert” the Albigensians failed miserably, since Pope Innocent III had to send out the crusaders to massacre 20,000 men, women and children. To think, all that bloodshed just to stop the Albigensians from calling the Roman Catholic church the Whore of Babylon, the pope the anti-christ, and denying Peter ever went to Rome, etc. There was one knight who was commanded by a papal legate to expel the Albigensians from their land. He said:
“How can we do it?…We have been brought up with these people, we have kindred among them, and we see them living righteously” (Age of Faith, Durant, 774).
