In his book, The Secret of the Rosary, St. Louis de Montfort relates that Blessed Thomas of St. John was a great devotee of the Holy Rosary of the Blessed Virgin Mary. As such, he was known for his powerful, moving sermons on the Rosary, which led people to adopt this devotion to their great benefit.
Furiously jealous of the holy man’s success with souls, the devil began to so torture Thomas that he fell sick, and was so ill for so long that the doctors gave up on saving his life.
One night, when the poor man thought he was near death, the devil appeared to him in a hideous form, coward that he is, seeking to frighten Thomas into despair.
But, making an effort, the good priest turned to a beautiful picture of Our Lady near his bed crying out with all his heart and strength:
“Help me, save me, my sweet, sweet Mother!”
“Do not be afraid, Thomas my son, here I am and I am going to save you. Get up now and go on preaching my Rosary as you did before. I promise to shield and protect you from your enemies.”No sooner had Our Lady pronounced these words, than the devil fled in a hurry. Getting up, Thomas found that he was perfectly healed.
Thanking the Blessed Mother with tears of joy, Blessed Thomas again went about preaching the Holy Rosary, now with renewed favor and gumption, and his apostolate and his sermons were enormously successful.
St. Louis the Montfort concludes this story saying, “Our lady not only blesses those who say her Rosary, but also abundantly rewards those who, by their example, inspire others to say it as well.”
