From a reader…
Pater, our parish priest has this book “Vatican II Weekday Missal” which he uses to celebrate Holy Mass. The problem that it is the old translation of the Missal.
My question is, when we attend that Mass using the old translation, does the bread and wine transubstantiates into the Body and Blood of Christ? Is that Mass valid or not?
If he sticks to the book, the text as it is in the now outdated and illicit book, he consecrates validly. Provided there are no other serious problems, Mass is celebrated.
He should not be using that book. He is obligation to use the current translation.
You might drop him a note asking, politely, why he is using the outdated and illicit text. I suspect that his reason is that he doesn’t like the new one, for one reason or another. If he persists in using the outdated text, you should inform your diocesan bishop, with a copy of the priest’s response.
If that doesn’t produce any results, you should notify the Congregation for Divine Worship and Discipline of the Sacraments.
By the way… if he doesn’t like the new translation, he can always use the proper language our our sacred worship, Latin.
