The problem is that certain parts of the Roman Rite…actually, virtually ALL parts of the Roman Rite…said goodbye to Latin after Vatican II and plenty of people were freely told by prelates, priests, nuns, CCD classes, grammar school religion, whatever, that “Latin is pre-Vatican II”.
In a dramatic repudiation of their own history and culture, Catholic leaders and rank and file by the bushel bought the whole lie.
So don’t cry me a river about the vernacular. The vernacular hasn’t been and isn’t the endangered species. Latin has been another story.
Latin IS superior for expressing doctrinal, theological complexities. That’s something any linguist will tell you. Latin doesn’t change, so we don’t have to have tedious “for all/for many” debates all the time. Latin avoids the bloody strife language can cause in some countries (in Belgium, it famously united Catholics of both Dutch and French persuasions).
Finally, Latin…along with the 2 other languages of the Rite (Hebrew, Greek) was a language pinned to the Cross. Because of the Cross, Latin, Greek, and Hebrew ARE inherently more sacred languages, and the Church has always esteemed them as such…until She learned better about everything in c. 1965.
Hence, a sacral language. The traditional Roman Rite has daily words from Latin, Greek (Kyrie, eleison), Hebrew (Alleluia, Amen, Sabaoth).
