This book, widely regarded as Saint Alphonsus Liguori's finest masterpiece, has for two and a half centuries stood as one of the Catholic Church's greatest expressions of devotion to the Blessed Virgin. Written as a defense of Our Lady at a time when Jansenistic writers were ridiculing Marian devotion, this classic work combines numerous citations from the Fathers and Doctors of the Church with Saint Alphonsus's intense personal piety to produce a timeless treasury of teachings, prayers, and practices.
