O Jesus, the true and infinite sacrifice, I adore Thee in the Blessed Sacrament, and I make an offering of Thy sacred body, which Thou didst deliver for us unto death on the cross, and Thy sacred blood, which Thou didst shed for our sins, in union with the priest who is about to say Mass. Eternal and merciful Father, the Father of Our Lord Jesus Christ, as well as Our Father! With the priest I offer Thee a pure, holy, immaculate sacrifice, the sacred bread of eternal life, the chalice of salvation, the body and blood of Jesus Christ, Thy Son. Deign to accept it, and be merciful to me a sinner. In the spirit of humility and with a contrite heart, I acknowledge, O my God, that I have sinned often and grievously in thought, word, and deed, through my most grievous fault. I know I have been guilty, and I beg pardon of Thee, O heavenly Father, through Thy infinite mercy, through the infinite merits of Jesus Christ, and through the intercession of all the saints. Amen.
