Although it would be decades before it could ever happen, English is now the universal language (lingua franca) that latin used to be, and could be the easiest way to have uniformity within the universal Church.
But there are benefits to using the dead latin language, the most obvious being that as a dead langauge, it won’t evolve and “scholars” can’t pretend that black means white - as they so often do in English.
An immediate benefit in the USA would be if the novus ordo was celebrated everywhere as VII ensisioned it - in latin.
Then parishes would not need to have spanish and english masses. Everyone would join to worship in the neutral language of the Church. It would be a real unifying experience.
It would take much catechesis, but it would be quite do-able. If there’s a will, there’s a way.
One of my favorite lessons with the children in Science class, is to teach them about Binomial Nomenclature, and Carolus Linnaeus.
The kids love to discuss how language has evolved, even in the last 50 years.
The theme song of The Flintstones sure takes on a new meaning using today interpretation of certain words.
