Let me give a personal example.
I used to travel extensively for business. This travel was international in scope.
On Sundays, I would seek out the local Latin Mass. Why? In that way, I could follow along and participate in the Mass. I had my own missal, so I could read the readings, and the only thing I would miss out on was the homily.
Otherwise, my only other choice was to sit there and try to follow along in French, Dutch, Korean, Polish or whatever happened to be the local language.
As Christians, are we not supposed to be welcoming of the stranger? If there was a foreigner visiting your parish, how to you pupose that they worship with you?
And as for learning the Latin, it was pretty easy. My father’s parish was about 1/2 Hispanic about the time Vatican II came out. So the parish priest there just began to say the NO Mass in Latin. That way, both the Anglo and the the Hispanics could worship together. Isn’t that the way God wants it?
What we have now is a Balcanization of churches. Hispanics have their priest and their Mass, and the Anglo have theirs. They are now two seperate communities that happen to share the same building.
The reintroduction of the Latin Mass ( in any form) will serve to unite the Church again under a common form of worship where everyone can participate.
