What do you now think of Holy Mass, O Christian? Can it be supposed that in the whole world there is any other good work whereby so many graces and fruits are placed within our reach? It is no longer possible to question the truth of the words of Father Sanchez quoted below:
“If Christians only knew how to profit by Holy Mass, they might acquire greater riches than are to be found in all the things God has created.” We have indeed a precious storehouse in the Mass: happy he who can earn treasures so great at the cost of so little labor! Who would willingly miss Mass? Who would not delight in hearing it?
Let us resolve never to lose an opportunity of hearing Mass, provided the duties of our state of life do not prevent us from doing so. To omit hearing Mass daily, merely from carelessness or indolence, would be a proof that we were either ignorant of or indifferent to the divine treasures it contains. God grant that those who read this book may in future appreciate more fully this pearl of great price, value it more highly, seek it more diligently!
