St Montfort’s teachings on Mother Mary have been very much accepted by the Church and by many popes. This book gives the reasons for this devotion and then explains its basic principles. It tells us that while true devotion to Mary is compulsory for all Catholics, the perfect devotion to Mary consists in consecrating oneself completely as slaves of Jesus through the hands of Mary and in living one’s life through Jesus. It also helps to meditate upon the mysteries of Jesus and Mary especially by reciting the Holy Rosary and must imitate her virtues. It also provides a summary along with insights from modern Popes and theologians.
