The Mass as Sacrifice
We must always remember that when we are coming to Mass, it is not just a social gathering or a club meeting, we are there for a purpose—to encounter Jesus. Sacrosanctum Concilium, the Vatican II decree on the sacred liturgy points out:
Christ is always present in His Church, especially in her liturgical celebrations. He is present in the sacrifice of the Mass, not only in the person of His minister, "the same now offering, through the ministry of priests, who formerly offered himself on the cross but especially under the Eucharistic species. By His power He is present in the sacraments, so that when a man baptizes it is really Christ Himself who baptizes He is present in His word, since it is He Himself who speaks when the holy scriptures are read in the Church. He is present, lastly, when the Church prays and sings, for He promised: "Where two or three are gathered together in my name, there am I in the midst of them" (Matt. 18:20).
This offers us some food for thought. Firstly in pointing out that the Mass is a sacrifice. It is not just a sacrifice, but it is the sacrifice, the sacrifice of Christ on the Cross. Sacrosanctum Concilium states:
At the Last Supper, on the night when He was betrayed, our Savior instituted the eucharistic sacrifice of His Body and Blood. He did this in order to perpetuate the sacrifice of the Cross throughout the centuries until He should come again, and so to entrust to His beloved spouse, the Church, a memorial of His death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a paschal banquet in which Christ is eaten, the mind is filled with grace, and a pledge of future glory is given to us.
This is not to say that we crucify Jesus each time we celebrate the Mass, rather we join in with the one, timeless, eternal sacrifice of the Cross. The Cross was not the end of the story. “We proclaim your Death, O Lord, and profess your Resurrection, until you come again.” In the Mass we celebrate the paschal Mystery, the life, death, resurrection, and coming again of Jesus, the Christ. We join now in the banquet of the Lord on earth until we join in the eternal banquet of the Lamb in heaven.
