"...text repeats that the priest's sacrifice (of praise and thanksgiving only) is "our" sacrifice..."
The Latin text of the Orate Fratres in the Novus Ordo still says "...meum ac vestrum Sacrificium...".
ICEL translates "...meum ac vestrum Sacrificium..." as "... our Sacrifice...".
A major part of the Novus Ordo problem is ICEL.
This may be true in part in the text. But the orientation of the New Mass is that of the community's action with the priest, not of the priest's action apart from the community. The New Mass makes the congregation essential; the Old Mass recognizes the congregation is not essential since only the Sacrifice matters, the Offering to the Father of the Son. The act of worship in the Old Mass is what is pleasing to the Father--hence the importance of Transubstantiation. We are left out of it. The locus of worship in the New Mass, on the other hand, is what's going on in the congregation, the celebration of its salvation. In this the Eucharist signifies our union as Christians--a virtual union, not the personal physical union of the individual with the Real Presence of Christ. This personal union with the Real Presence is Catholic, in accordance with the teaching of Trent; the virtual union of the congregation is according to the Paschal Meal theology which is Protestant. These modes of worship are worlds apart.
