The Mass is truly a "Sacred Treasure," and, alas, our cold, dead faith allows it to remain so. If we valued it as we ought, we would hurry every morning to the church, careless of the snows of winter and the heats of summer, in order to get a share of the riches of this treasure. The Saints knew the value of one Mass: that was a dark day in their calendar on which they were deprived of the happy privilige of saying or hearing Mass. Sacred Treasures of the Mass by St. Leonard of Port Maurice will stir the soul to practice the Catholic faith with zeal and ardour. This saintly writer truly inspires the Christian soul to strive for perfection through deep and devout devotion to the Mass.
