1970 Missal Prayers Super oblata, with Commentary
Take a look at that link - you'll see a lot of the prayers super oblata in the Bugnini-produced Missal are taken directly from the Secrets in either the 1962 Missal or one of the other ancient western missals. In the Gregorian Sacramentary the ONLY offertory prayer was the Secret. The rest were all added later, after the eighth century. It follows, therefore, that the Secret/super oblata is all that is necessary to express the offertory idea.
The only Offertory prayer may have been the Secret at one time--but all else affirmed the propitiatory sacrifice. You can't isolate a part from the whole. What is grotesque about the Novus Ordo is just this sort of practice--pretending the Novus Ordo is no different from earlier Masses in its meaning. But this is not true. Here is the Novus Ordo prayer--the offering of the gifts:
"Blessed are you, Lord, God of all creation. Through Your goodness we have this bread to offer which earth has given and human hands have made. It will become for us the bread of life."
Nothing about the spotless Victim about to be sacrificed for our sins. No Judica me psalm recited by the priest at the Introit to underscore our need for expiation. It's just, "Thanks, Lord for the bread. Thanks for the wine." Big deal. Nothing could be more banal, more prosaic. It's a mere blessing before a Meal--which is the whole point. The celebration is of a memorial meal in the Protestant fashion--and at a table, not an altar.
