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.
