True Devotion to Mary

St. Louis De Montfort was a French priest and missionary known for his deep devotion to the Virgin Mary and his contributions to Mariology, including the influential book "True Devotion to the Blessed Virgin." Although published after his lifetime, the book emphasizes Mary's role as the key to the heart of Jesus and promotes the practice of consecration to Christ through Mary. It has had a lasting spiritual impact, notably influencing figures like Pope John Paul II.
