Zerinus likes to play these games, and then pretends he understands Catholic beliefs better than Catholics.
Catholics have already explained that the Mass (also called the “Holy Sacrifice of the Mass”) is a sacrifice. Catholics believe that Jesus Christ died once and for all on the cross, and is not re-sacrificed, or killed again on our altars. Instead, the Mass is a participation in the same, once and for all sacrifice on the cross. We believe that the atonement is eternal, and the Mass is a participation in it, since it is a “re-presentation” of that same sacrifice, done in an “un-bloody” manner (since Jesus Christ died once). The chief presider at Mass is Jesus Christ, the eternal High Priest. Jesus Christ offers Himself for us at Mass. The priest/bishop is Christ’s representative, and acts with His power. Here are the important quotes from the Catechism of the Catholic Church:
**II. What is this Sacrament Called?
1330 The memorial of the Lord’s Passion and Resurrection.
The Holy Sacrifice, because it makes present the one sacrifice of Christ the Savior and includes the Church’s offering. The terms holy sacrifice of the Mass, “sacrifice of praise,” spiritual sacrifice, pure and holy sacrifice are also used,150 since it completes and surpasses all the sacrifices of the Old Covenant.
The sacrificial memorial of Christ and of his Body, the Church
1362 The Eucharist is the memorial of Christ’s Passover, the making present and the sacramental offering of his unique sacrifice, in the liturgy of the Church which is his Body. In all the Eucharistic Prayers we find after the words of institution a prayer called the anamnesis or memorial.
1363 In the sense of Sacred Scripture the memorial is not merely the recollection of past events but the proclamation of the mighty works wrought by God for men.184 In the liturgical celebration of these events, they become in a certain way present and real. This is how Israel understands its liberation from Egypt: every time Passover is celebrated, the Exodus events are made present to the memory of believers so that they may conform their lives to them.
1364 In the New Testament, the memorial takes on new meaning. When the Church celebrates the Eucharist, she commemorates Christ’s Passover, and it is made present the sacrifice Christ offered once for all on the cross remains ever present.185 "As often as the sacrifice of the Cross by which ‘Christ our Pasch has been sacrificed’ is celebrated on the altar, the work of our redemption is carried out."186
1365 Because it is the memorial of Christ’s Passover, the Eucharist is also a sacrifice. The sacrificial character of the Eucharist is manifested in the very words of institution: “This is my body which is given for you” and "This cup which is poured out for you is the New Covenant in my blood."187 In the Eucharist Christ gives us the very body which he gave up for us on the cross, the very blood which he "poured out for many for the forgiveness of sins."188
1366 The Eucharist is thus a sacrifice because it re-presents (makes present) the sacrifice of the cross, because it is its memorial and because it applies its fruit:
Code:
[Christ], our Lord and God, was once and for all to offer himself to God the Father by his death on the altar of the cross, to accomplish there an everlasting redemption. But because his priesthood was not to end with his death, at the Last Supper "on the night when he was betrayed," [he wanted] to leave to his beloved spouse the Church a visible sacrifice (as the nature of man demands) by which the bloody sacrifice which he was to accomplish once for all on the cross would be re-presented, its memory perpetuated until the end of the world, and its salutary power be applied to the forgiveness of the sins we daily commit.189
1367 The sacrifice of Christ and the sacrifice of the Eucharist are one single sacrifice: “The victim is one and the same: the same now offers through the ministry of priests, who then offered himself on the cross; only the manner of offering is different.” "And since in this divine sacrifice which is celebrated in the Mass, the same Christ who offered himself once in a bloody manner on the altar of the cross is contained and is offered in an unbloody manner. . . this sacrifice is truly propitiatory."190
1368 The Eucharist is also the sacrifice of the Church. The Church which is the Body of Christ participates in the offering of her Head. With him, she herself is offered whole and entire. She unites herself to his intercession with the Father for all men. In the Eucharist the sacrifice of Christ becomes also the sacrifice of the members of his Body. The lives of the faithful, their praise, sufferings, prayer, and work, are united with those of Christ and with his total offering, and so acquire a new value. Christ’s sacrifice present on the altar makes it possible for all generations of Christians to be united with his offering.
In the catacombs the Church is often represented as a woman in prayer, arms outstretched in the praying position. Like Christ who stretched out his arms on the cross, through him, with him, and in him, she offers herself and intercedes for all men.
