It isn't even close.
According your catechism, the sacrifice of the mass is an unbloody one, which is worthless killing, because without the shedding of blood there is no remission of sins. Jesus shed His blood. And CCC says it's bloodless.
Christ died on a cross, not an altar.
Jesus gave Himself, no priest offered Him up to God as a sacrifice for our sins.
Jesus said *It is finished*, while the RCC says it isn't finished but is ongoing.
Nope, not the same death at all.
If you are going to reference the Catechism of the Catholic Church then give a complete reference:
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."N.B. the line: "The sacrifice of Christ and the sacrifice of the Eucharist are one single sacrifice." The shedding of the Blood of this one sacrifice that is made present at the Mass took place on the Cross.
Jesus said *It is finished*, while the RCC says it isn't finished but is ongoing.
What was finished was the institution of the new Passover at which he also gave the instruction "do this in memory of me."
