For Saint Louis de Montfort (1673-1716), the Rosary is the most powerful instrument of the mission. The following is his commentary on each component of the Rosary (see A Moment with Mary of April 28, 2024):
"Moreover, at the end of each decade, it is good to add the Glory be to the Father, and to the Son, and to the Holy Spirit. As it was in the beginning, is now, and shall be forever. Amen."
Montfort explained the mysteries with pictures from the Gospel, in large images. He said that the Rosary conforms us to Jesus. Our Lord wants us to remember his blessings. Meditating on the mysteries is a great means of perfection and sanctification (cf. The Secret of the Rosary, SR).
“The Rosary, made up of the Lord's Prayer and the Hail Mary, is this clear and ever-flowing water which comes from the fountain of grace, whereas other prayers which they look for in books are nothing but tiny streams which spring from this fountain.” (SR 38) There are countless examples of the wonders worked by the Rosary (SR 98-115).
“I, who write this, have learnt from my own experience that the Rosary has the power to convert even the most hardened hearts. I have known people who have gone to missions and heard sermons on the most terrifying subjects without being in the least moved; and yet, after they had, on my advice, started to say the Rosary every day. they eventually became converted and gave themselves completely to God. When I have gone back to parishes where I had given missions, I have seen tremendous differences between them; in those parishes where the people had given up the Rosary, they had generally fallen back into their sinful ways, whereas in places where the Rosary was said faithfully I found the people were persevering in the grace of God and advancing in virtue day by day.” (SR 113)
