Please let me begin be saying that I like going to the Tridentine Mass, but, truth be told, the Tridentine Mass is liable to criticism. And I believe those criticism take all the force out of arguments against the Catholocity of the Novus Ordo.
Now, it must be admitted that the Novus Ordo mentions the sacrifice several times; and yet it does not specifically say it is propitiatory. However, the first Offertorty prayer of the TM starts out by saying this "spotless host" is offered for the sins of the priests. But does not say it is propitiatory for anyone else. It does not mention a sacrifice of Jesus, let alone the one on the Cross. The wine is not mention there in relation to atonment, so that sacrifice of Calvary, effected by the separation of the blood from the body, is not even implied within the TM. Nowhere does the Tridentine mass say the sacrifice during the mass is the same as that of Calvary. Since it was promulgated in the face of the Reformation, that is quite an ommision.
Standing alone, this first prayer of the Offertory can easily be interpreted to be a denial of the real presence by apparently stating the the unconsecrated host wipes away sin. The NO is clearer, when it begins the second half of the Mass by asserting that the gifts are the "work of human hands" which will "become the bread of life" and "our spiritual drink". The Tridentine Canon first asks God to bless "these offerings, these holy and unspotted oblations which, in the first place, we offer You for Your Holy Catholic Church, that You would deign to give her peace and protection." So the oblations are already present?? Of course, the Novus Ordo says "this, our sacrifice" before consecration, but this confusion is much more explicit in the TM.
However, the Tridentine Mass says several times that it is offered for "our salvation", while the Novus Ordo merely once says for "our good". Good for the TM!!
Nonetheless, in the Commemoration of the Living, the TM speaks of a "sacrifice of praise" which "we offer to You, OR who themselves offer to You". The Tridentine Mass does not distinguish the manner in which the priests offers the sacrifice vs the way the laity do. In fact, the pray right after the consecration of wine says "we Your ministers, as also Your holy people, offer to You...".
The "all-perfect victim" is then mentioned, but is lower-cased in the Latin missals, and the next prayer mentions Melchisedec's "spotless victim" as well.
Finally, much ado is made over Ottaviani's Intervention?? However, not many seem to be aware that Rome gave Ottaniani a critical rebuttal. I wonder if anyone on here knows where that can be found on the internet.
God love you!
