By Benjamin Starnes, Church Militant - One of the oldest devotionals in the Catholic Church is the Rosary, the importance of which is overlooked by too many Catholics. But the 15 promises of the Blessed Virgin Mary offer something to catch the attention of anyone interested in obtaining happiness and joy... Of particular note is a story recounted by St. Louis de Montfort in his brief spiritual classic The Secret of the Rosary. It deals with the 10th promise of the Rosary: "The faithful children of the Rosary shall merit a high degree of glory in Heaven."
