The apostles and subsequent bishops preached Jesus’ message in the local language. That was the Holy Ghost’s message from Pentecost so they could reach those outside Judea.
Switching to Latin and having missiles printed when many couldn’t read closed off the gospel to only the aristocrats and the clergy.
THE traditional mass is in the local language, so people could convert to the church and understand the message Jesus came to teach us.
**missiles** Like traveling in space objects or weapons?
Or do you mean missals?
If they can't read, what difference does it make what language the missal is printed in? Catholics are flocking to Latin masses today, and they don't speak it either.
Furthermore, the homily is in the local language. The liturgy is in latin.
You really need to get some background before trying to diagnose someone else.
