ZING!
WRT to the vernacular, I’m a recent convert and I am still learning to better understand the Latin. It is useful to have translations available for the neophytes, but I think if you ran english/latin translations in the missals, that people would soon pick up the latin and would learn to understand it.
I’m a deaf person, so I really don’t care that the mass is in English and Latin, provided that I have a songsheet to read off of. I can’t hear the priest anyways.
