“Did you know that missing Mass on Sunday is a mortal sin?” my friend asked excitedly over the phone.
“I was reading the Catechism you gave me, and it says that missing Sunday Mass is grave matter. So a person could essentially end up in hell for missing a single Sunday Mass. Isn’t that too extreme?”
From his perspective, my friend is right; it does seem extreme. But he is approaching the Mass through a Protestant lens. The Mass, however, is not merely a formalized worship service.
So what is the Mass?
It is something I cannot fully explain, any more than I can fully explain or comprehend the mysteries of God. The Mass is a mystery. One aspect of that mystery I would like to focus on here is the sacrifice of the Mass, and I will do so with the help of a picture. They say a picture is worth a thousand words, and my thousand-word essay on the Mass is contained in the image at the top of this post.
The image is an artist’s rendering of the reality of the Mass. The sacrifice of the Mass is Christ’s sacrifice on Calvary made present in our own time for the sins of the world. This is what takes place at every Mass: we are, in a real sense, standing at the foot of the Cross.
God exists outside of time. To Him, yesterday, today, and tomorrow are part of an eternal present. Events that occurred two thousand years ago remain ever-present before Him.
Christ’s sacrifice is not repeated or renewed at every Mass. Rather, the one sacrifice offered on Calvary more than two thousand years ago is made present to us in an unbloody manner. Who can fully fathom such a mystery?
Take another look at the picture and pay particular attention to the angel. Then listen to these words from Eucharistic Prayer I:
“Humbly we beseech Thee, almighty God, to command that these our offerings be carried by the hands of Thy holy Angel to Thine altar on high, in the sight of Thy divine Majesty ...”
An angel is present at every Mass, carrying the sacrifice made present among us to the heavenly altar. This is a reality we should contemplate whenever we attend Mass.
Once we recognize what truly takes place at Mass, it becomes easier to understand the seriousness of deliberately missing even a single Sunday Mass. Remember this image, and then consider what you are walking away from when you choose not to attend.
At its heart, mortal sin is the willful rejection of God and His love. To deliberately miss Mass on Sundays and holy days of obligation is, in essence, a rejection of the One who invites us into communion with Him.
There is much more that could be said about the Mass. Few people have penetrated its mystery as deeply as Saint Pio of Pietrelcina. To help us better appreciate this great gift, I will conclude with his words:
“It would be easier for the world to survive without the sun than to do without the Holy Mass.”
