Ummmnnhh,
In Rome, the crowds are multi-national. Latin works for all people there, vs. English for the Aussies, and Amuhr-kin for the US folks.
More welcoming, you know...
Excellent point. If all Catholic Masses were the same rite and in Latin, we could have our missals in our various languages, and get rid of Spanish mass, Vietnamese mass, etc. etc., and have all Catholics worship in essentially the same way. You could walk into a Catholic church anywhere in the world, much less the same town, and recognize that you were actually attending Mass. How could you get any more welcoming than that? Who would have ever thought of such a great idea?
