Latin does have its advantages. Some time ago, I was sitting next to a couple obviously fresh in from Mexico. The wife was struggling to keep up with the missalette. The husband obviously had no clue.
I thought then that if we at least could all say our basic prayers in Latin, we would both know what we are saying and we could do it together.
Most of us can comprehend the meaning of "Sanctus, sanctus, sanctus" without a single lesson in Latin. Liturgical Latin is really not that difficult.
You said it, siunevada!
If we are The Chuch Universal (and I know I'll get flamed for this) why are we not praying with each other in common language (aka the language of the Church)?
