Pedantic point: The whole "reading the bible in Latin" is a very Catholic thing (and maybe Orthodox?). The Protestant churches I've been in has read from the bible in the native tongue, and it was indeed one of Luther's criticisms of the Catholic church.
I'm not Catholic, but I think they stopped requiring the reading of scripture in Latin around 1960 and The Second Council of Vatican, AKA Vatican II.
I think Latin is still used as part of the traditional service, but it's mostly ritualistic. What I remember from attending Catholic services years ago is a lot of standing up and sitting down while chanting in Latin, followed by a sermon delivered in English.
It's not universal either. I've grown up in a catholic-obsessed country and not a single mass I've been to had Latin elements or chanting. All in native language in mid 80s.
