Let us not forget that the Catholic church is the universal Church. The evangelization of the world to Christ is not immune (for lack of a better word) to practical considerations. One of those is to preach the same message to all regardless of linguistics. Latin was and is unifying. As it was in the past and still is today.
Perhaps there is too much emphasis on “partcipatory” worship.
I stand by comment and the acts of the apostles. I don’t want to attend any of your further lessons.
