Exactly: the liturgy was adapted to the dominant language despite the language of Christ.
In the Roman Empire, that was Latin; to use some localized language would only serve a local culture, and to use a dead language would be pointless.
Today, it’s English; to use some localized language would serve a local culture, and to use a dead language is pointless.
Latin is not a dead language. 70 % of our vocabulary is descended from Latin including many of the words I am using now. Western Civilization was founded on the Latin language and French, Spanish, Portuguese, Italian, and Romanian are direct descendants.
Latin was not only the official language of the Church for centuries, but it was also taught in the public schools as well.
Think of the improvement we would see in our public education if Latin was reintroduced. There would be a renewed interest in history, Western Civilization, the classics, ancient literature (like the works of Cicero and Caesar’s Commentaries), philosophy, reason, and logic. Our Founders understood Latin and founded our Republic much on the basis of the Old Roman Republic. They even copied much of the architecture for our new capital. I see so much positive potential by reintroducing Latin into both our spiritual and public lives. Vatican II has caused so much damage. The liberals nearly ruined the Church much as they have ruined public education. I see no down side to reintroducing Latin to public education and the Church.
