I attend Mass in a Polish Parish that has only two Priests, both of which were born, educated and ordained in Poland. Both speak heavily accented English. This church has only two Masses a week in English, and most of the attendants who attend these English Masses have Polish as their first language.
In my observation, neither the Priests nor the congregation have any problem with the new, more accurate translation of the Mass in English. In fact, the English translation is quite close to the Polish translation of the Latin Mass, just as I am sure is the Spanish translation.
I think the reason for the deviation in the original translation, was the well meaning, but ill advised attempt to make the Mass more palatable to our Protestant bretheren in the US.
The translation of the Mass used until the recent reform was closer to the Episcopal Churches Book of Common Prayer than it was to a direct translation of the Latin.
Unfortunately, we have two or three generations of people who never knew the beauty of the Latin prayers, and it will take them a while to adapt…just as many of us had to adjust to the Mass in languages other than Latin.
