As someone who converted to the Church three years ago, and who did not even know about the Tridentine Mass until a few months after joining the Church, I can categorically state that the notion that the NO mass does not emphasize Our Lord’s Sacrifice is pure nonsense and hogwash.
Consider the fact that to this day, not a single solitary Protestant sect that has some notion of the Liturgy, like Lutherans or High Church Anglicans, and certain Presbyterians, have adopted any of the prayers of the Pauline Mass, specifically because it is clearly sacrificial in nature. The notion that the NO mass was toned down for ecumenical reasons is nonsense. Every single major Protestant body that has looked at the prayers of the Pauline Mass in considering whether to “borrow” from them has rejected them, because they are clearly sacrificial. And as far as I know, plenty of Protestant Fundies still attack the mass today, regardless of its form, as being “blasphemous” because it is clearly sacrificial.
So we have a rather odd situation–there are allegations that the NO mass is “Protestantized,” yet the only people making these allegations are supposed “Traditional Catholics.” Not a single, solitary Protestant in the last forty years has even attempted to argue that the NO Mass is similar to his sect’s form of worship. Hardly the case of the Mass being Protestantized. It a strange situation indeed if the only ones who are claiming that the Mass has been Protestantized aren’t even Protestant themselves!
Like I said, I didn’t even know about the Tridentine Rite until after joining the Church. But as I was preparing for reception into the Church, I would go to daily mass, in the Pauline Rite, following everything as closely as I could (nor receiving communion at that point, obviously, since I wasn’t yet in the Church). Its sacrificial nature struck me right from the very beginning, and I never got any impression that it was a mere “communal meal,” or anything like that.
Now, when I did see the Tridentine Mass for the first time, I fell in love with it. It is a beautiful rite. But while I did immerse myself fully in the Tridentine Mass, I never once considered the NO Mass to be “Protestantized,” because it isn’t.
And the notion that the “for many” has been translated as “for all” in order to be more ecumenical is also just as ludicrous. There are plenty of scriptural references to Our Lord’s sacrifice being “for all.” Some choose to accept that Sacrifice and its merits, and others don’t. Our Lord died for all. The argument that it is wrong to translate it as “for all” hints at Jansenism.
