Not only was it wrong, but it was actually* heretical* according to what those words actually man. The words “for you”, and “for many” in the consecration of the sine have a meaning of their own. One place you can find this talked about is the
Catechism of Trent, under the section titled
Explanation of the form used in the Consecration of the wine.
I personally would also argue (and if someone wants to challenge me, do so), that the Mass you attended was
invalid. That means the “mass” was not a Mass at all. The Sacrifice did not take place.
You should avoid this politically correct heretical Preist like you would a Leper. Don’t try to “convert” him; avoid him. Go back to the FSSP Church. They have real Catholic Priests there. Stay after for coffee and donuts and get to know the people. That’s what you should do.
