"True Devotion to Mary" is actually one of the best written books about devotion to the Blessed Mother that was ever written. In my experience, most books about Mary are flowery, poetic works that are not very informative, almost like romantic poetry. But this book is eminently practical. De Montfort gives the readers excellent reasons why they should have a devotion to Mary. Why not just worship Jesus? Why have this devotion to a creature? De Montfort reminds us that Mary was Jesus' first Disciple and his most devoted one. She is His only human biological parent and she said "Yes" to the angel which ushered in the Incarnation. She was humble, and yet the very ediface of human salvation rested on her mission as Mother to the Living Word. She was a servant, just as Jesus calls all of us to be. She tells us, as she told the servants at the Wedding at Cana, "Do as He tells you." And she does this as well. In return for her devotion, Jesus gives Mary to the Disciple at the Foot of the Cross, "Behold your Mother" and "Behold your Son." And so He gave Mary to all Disciples. Because she was the gate to the Incarnation, so is she the gate to all Graces.
In this book, De Montfort addresses several issues that arise in the devotion to Mary. He eloquently addresses the accusation that Devotion to Mary is really idolatry, the worship of a creature as though she were God. But he also addresses several of the issues that keep the Christian away from Mary. Why, after all, should a great man like myself be devoted to this poor Jewish peasant girl? This attitude of arrogance is the very thing that drove Satan and his angels in rebellion against God, and by being devoted to Mary, the Christian can guard against such faith-killing arrogance. Many people accuse Christians of crimes such as presumption, judgementalism and elitism. It is a shame that many Christians are guilty of these attitudes. But Mary was none of these things. She was completely devoted to God, yet she never took it as anything other than service through love. She never tried to take first place. By mimicking her humility, forgiveness and love, the Christian grows by light-years closer to Jesus. Many people say that Christians who have a devotion to Mary are preferring the Mother over the Son. But there is no division between Mary and her Son. In drawing close to Mary, we by necessity draw close to the Son, in a much more intimate way than we could otherwise do. No Son could say no to His Mother. Doing so would violate the 10 commandments, and his very piety as a good Jew. And so, Jesus could not say no to His Mother's entreaties on our behalf. How could we, as Christians, not take advantage of such an amazing blessing?
When reading this treatise, please avoid the old translations with the "thees" and "Thous". Get a good, modern translation that reflects De Montfort's vivid and forceful vernacular in the French. The end of this book contains the prayers, readings and rites associated with the Consecration to the Sacred Heart of Mary. Many people have undergone this consecration. If you choose not to do it, it is beneficial to read these last sections anyway, since they give the reader an excellent insight into the scriptural and moral teachings associating with the consecratation.
Overall, this book is a must read for anyone who is interested in Devotion to the Mother of God.
