Catholics believe that Jesus is truly present, body, blood, soul and divinity, in the consecrated host at Mass. This means that the Eucharist is not simply bread, but Jesus himself.
When viewed in this light, it should pain us whenever we hear or witness offenses against the Eucharist. It is not an offense against a piece of bread, but an offense against the One we love with all of our heart, Jesus Christ.
In order to repair the spiritual damage done in such a situation, the Church provides the following prayer to be said.
I adore Thee profoundly, my Jesus, true Bread of life eternal; and by this my act of adoration I would make Thee compensation for all the wounds with which Thy Sacred Heart bleeds daily to see the profanation of those churches wherein Thou abides beneath the sacramental species, to receive the love and adoration of Thy people. I offer Thee, in reparation for all those irreverences, that most Precious Blood which Thou didst shed and I say every moment:
Blessed and praised every moment
Be the most holy and divine Sacrament.
And today we celebrate...
