The CCC and the current NO Missal define the Mass as a sacrifice.
Please substantiate. I read through every bit of the CCC that addresses the Liturgy on the Vatican website just a few days ago and could not find the word sacrifice, nor any mention of any propitiatory function of the NO or even the expiation of sins. Just page after page of syrupy feel good goo and repeated references to something called the "Paschal Mystery." As for the Missal, are you certain, if a reference to a sacrifice even is in there, that it isn't in some non-official filler typical only to the edition you use?
The new translation will read:
To you, therefore, most merciful Father,
we make humble prayer and petition
through Jesus Christ, your Son, our Lord:
that you accept and bless these gifts, these offerings,
these holy and unblemished sacrifices,
which we offer you firstly for your holy catholic Church.
Be pleased to grant her peace, to guard,
unite and govern her throughout the whole world,
together with your servant N. our Pope and N. our Bishop,
and all those who, holding to the truth,
hand on the catholic and apostolic faith.
