In his book, The Secret of the Rosary, St. Louis de Montfort writes of a pious but self-willed lady who lived in Rome. She was so devout that she put many a religious to shame.
One day, hearing of the holiness of St. Dominic, great apostle of the Rosary, she decided to make her confession to him. For penance the saint told her to say a Rosary and advised her to make it’s recitation her daily practice.
“But, Father, “ she protested, “I already say so many prayers and practice so many exercises…I walk the Stations of Rome every day, I wear sack-cloth and a hair-shirt, I scourge myself several times a week, and often fast…”
St. Dominic insistently advised that she adopt the recitation of the Rosary, but she would not hear it. Moreover, she left the confessional horrified at the methods of this new spiritual director who wanted to impose on her a devotion for which she had no taste.
One day, when she was saying her prayers, she was shown a vision. In this vision she saw her soul appear before the Supreme Judge. She also saw St. Michael holding the scale of her life. On one side he placed all her prayers and penances, and on the other all her sins and imperfections. Down went the scale on the side of sins and imperfections, outweighing all her good works.
Wide eyed, the good lady cried out for mercy, and turned to Our Lady imploring her help. Our Lady then gently set down on the tray of her good works the only Rosary she had ever said, which was the one St. Dominic had imposed on her as a penance.
This one Rosary was so heavy that it outweighed all her sins as well as good works.
Our Lady then reproved her for having refused to follow the counsel of her son Dominic and for refusing to adopt the practice of the daily recitation of the Rosary.
When the lady came to, she rushed to St. Dominic and casting herself down at his feet, told him what had happened. She begged forgiveness for her unbelief, and promised to say the Rosary faithfully every day. By this means she grew in holiness, and finally attained the glory of eternal life.
Thus says St. Louis de Montfort, “You who are people of prayer, learn from this the power, the value and the importance of this devotion of the holy Rosary when it is said with meditation on the mysteries.”
