mfbukowski,
I scanned the Catholic Encyclopedia article (reading the CE makes my eyes glaze over), and I’m a little unsure as to how you came to the conclusion that the Mass is “not a re-presentation of Calvary”, that “the sacrifice of the mass is the sacrifice of the last supper, not Calvary”. The article states this:
“Thus, the Church, as the mystical Christ, desires and must have her own permanent sacrifice, which surely cannot be either an independent addition to that of Golgotha or its intrinsic complement; it can only be the one self-same sacrifice of the Cross, whose fruits, by an unbloody offering, are daily made available for believers and unbelievers and sacrificially applied to them.”
As far as the words “unbloody”/“bloody”, the Catechism (which as you know is an official Catholic source) uses the word “unbloody” to describe the Mass, hence why it is frequently used to describe it.
Catholics have been saying that the Mass is a re-presentation of the sacrifice on the cross at Calvary because that is also what the Catechism states:
"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”
"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 "
etc.
As we can see, the Catholic Church officially teaches that the Mass is a re-presentation of the sacrifice on the cross at Calvary.
Now, what does this have to do with the Last Supper? Well, Catholics (and Orthodox I assume) of course believe that at the Last Supper, the bread and wine became the body and blood of Christ. I see that the Catholic Encyclopedia states that the Mass is a “continual repetition…of the Sacrifice accomplished at the Last Supper”. It also describes the Last Supper as an “anticipatory commemoration of the sacrifice of the Cross”. I think that it would be in line with Catholic theology to state that, since it is believed that at Mass there is a travel back in time to Calvary to “re-present” that sacrifice, the Last Supper was a travel forward in time to “re-present” (in anticipation) the sacrifice of the cross. I don’t think that Catholics would ever say that the Last Supper was a separate sacrifice from the Cross, but that they are part of the same sacrifice (especially since Catholics believe that the Last Supper was the first Mass). I think this quote from the Council of Trent is helpful:
“[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.”
So, I just wanted to make sure we all see that the official Catechism clearly equates the Mass with the sacrifice on the cross at Calvary, and states that the Mass is a re-presentation of the cross in an unbloody manner. If the Catholic Encyclopedia states that the Mass is not a re-presentation of the cross, it is in error, since official Catholic teaching says otherwise.
Hope that was helpful.
