I know some parishes bought this book to use in classes to teach their parishioners about this Holy Mass and what goes on and why.
"If we would live the Mass, we must assist at it. And if we would assist at it, we must understand it. If Mass for you has become routine, a conforming to anything custom, simply a family habit, or to avoid mortal sin. "The Heart of the Mass" is the book to read.
This book dissects the Holy Mass into its component parts, prayer by prayer, phrase by phrase, in Latin with parallel English. Just what are we praying? Why? When? For whom? With whom?
It synthesizes explanations from the Fathers and Doctors, revelations to Saints, teachings of the Church, history and mystic commentary. Tells you what the celebrant and ministers are doing and the symbolism of their gestures. A chapter on articles used for Mass and their spiritual significance. Proposes meditations and the benefits of devout participation. Acts of oblation."
