Just as the light of the moon is actually cast by the sun, devotion to the Mother of God is equally an effort toward a better relationship with her son. This simple principle has been understood from the earliest ages of Christianity, before the splits away from the Church He founded, indeed before the Bible was even written (reading on the early Church in this regard is highly recommended). Mary is central to the life of Jesus, and thus central to us, and there simply is no better understanding than that.
Saint Louis-Marie Grignion de Montfort (31 January 1673 – 28 April 1716) was a French Roman Catholic priest and Confessor. In addition, he was one of the great writers on the topic of Mariology. His grandest work on the topic was his “True Devotion to Mary.” It has been inspirational to many since, with Pope St. John Paul II saying that reading this work was a “decisive turning point” in his life.
