Holy Thursday Prayer to Appreciate the Mass

O Lord Jesus, in order that the merits of your sacrifice on the Cross might be applied to every soul of all time, you willed that it should be renewed upon the altar. At the Last Supper, you said: "Do this in remembrance of me." By these words you gave your apostles and their successors the power to consecrate and to the command to do what you yourself did. I believe that the Mass is both a sacrifice and a memorial- reenacting your passion, death and resurrection. Help me to realize that the Mass is the greatest gift of God to us and our greatest gift to God.
