We have Mass to worship and to receive God’s grace, to unify with Him and with other worshipers through the sacrament of the Eucharist. As a sacrament, it is that Jesus Himself acting through the Eucharist, and supplies all the graces we derive from it.
At Mass we are able to stand mystically at the foot of the cross and witness for ourselves the same self-sacrifice of Jesus, in an unbloody manner.
Mass is a celebration of this sacrifice. It is the active participation of all that come together in the place of worship. We do not come to Mass simply to receive something passively or to watch a show; we come as participants embracing the grace Christ pours out for us shed by His own blood on the cross.
Eternal Father, we humbly offer Thee our poor presence and that of the whole of humanity from the beginning to the end of the world at all the Masses that ever have or ever will be offered. We offer Thee all the pains, sufferings, prayers, sacrifices, and joys of our lives, in union with those of our dear Lord Jesus here on earth. May the Most Precious Blood of Christ, all His blood and wounds and agony save us, through the Sorrowful and Immaculate Heart of Mary. Amen.
O Jesus, I believe that Thou art truly present in the Blessed Sacrament. Although my eyes and tongue tell me that I have received only bread, yet my faith tells me that I have received Thy Body and Blood. I believe, Lord; help Thou my unbelief, I adore Thee as my God and my Savior. Amen.
Soul of Christ, sanctify me. Body of Christ, save me. Blood of Christ, inebriate me. Water from the side of Christ, wash me. Passion of Christ, strengthen me. 0 good Jesus, hear me. Within Thy wounds hide me. Suffer me not to be separated from Thee. From the malignant enemy defend me. In the hour of death call me, and bid me come to Thee, that with Thy saints I may praise Thee forever and ever. Amen.
