I have only been to one such Mass - and I can see the merits of it - and the problems inherent with it. I also see the merits of the Mass in English - and the problems inherent in that.
Neither way is without problems. Naither way is without mertis.
But one way - the English-language Mass - is the only one in which grave abuse can occur rather easily.
I am fortunate to be in one of the rare parishes where such error (in English) never surfaces.
Deo gratias!
