Priest of God,
Say* this Mass as if it were your first Mass.
Say this Mass as if it were your last Mass.
Say this Mass as if it were only Mass.
What if we could only go to Mass (or only receive Communion) once in our life? Imagine the preparation we would put into it! The focus! There would probably be a religious order or two with the sole mission of guiding retreats for people who were about to go to their only Mass. There would be an intense follow-up, too. For the rest of your life, you would go back in prayer to that one most sacred moment of encounter with Jesus.
Or what if you could only, in all your life, make one Eucharistic Holy Hour? How would you prepare for it? How would you actually make it?
Sometimes I find myself dreading the hour of adoration. I'm tired, or unfocused, or just plain ornery. It can be easier to bury myself in work (make that, "activity") than in silence with the Word of God. But...what if this hour were my very first hour with the Lord? What if it were to be my very last? What if it were the only hour I would spend in this life with the Eucharistic Jesus?
*The language of the times was that the priest would "say" the Mass, and the faithful would "hear" it.
