I read that in the 12th Century Pope Innocent III said that " If a future Pope was to change all Rites of Sacraments he would put himself outside the Church" and…In 1441 Florence, Pope Eugene IV held the same…and finally at the 7th session of the Council of Trent, on the Sacraments in general, this was made dogmatic…in the Canon XIII …"If anyone was to say that the traditionally handed down Rites used in the solemn administration of Sacraments can be held in disdain or be shortened or be changed into new ones by whomsoever (ques cum que) he would place himself outside the Church…pretty clear to me…How can a subsequent Pope change Dogma…if it’s possible, then wouldn’t it be just as possible that a future Pope would question, alter, change the Dogma of the Assumption…seems unlikely…but, honestly…where do we draw the line…I’ve posted this comment/question,although admittedly probably not that eloquantly,but haven’t had anyone from this site…or CA…offer an explanation…my comments are sincere…latin is a precise language…one can argue endlessly pro/con the Latin liturgy…I’m sure the words of consecration would be just as valid in swahelie (if spelled correctly)…for me it’s just everything…the music, Priest facing the people, (O.K. let me hear from you about the early church here,), I’ve been to Catholic Churches where It took me 10 minutes to find the Tabernacle…it’s a lot more than the language…but it’s important…everone seems anxious to bash the Trads as being radical…I disagree…PAX
NO Pope will ever chance the Sacraments, however the languange they are given with has zero impact in their efficacy.
We have absolute assurance of this.
If this was NOT the case the words of institution would need to be said in Aramaic. OK

Our Lord did not come to revert Babel and impose a 1 world language, He came to bring us to God, when we join him there will be no need for language at all.
Also to further show as WHY the Church has slowly allowed the usage of “vernaculars” (more than one as there are many languanges people speak)
Consider this, all the approved apparitions have something in common.
Our Lady of Guadalupe spoke to San Diego in Nahuatl (Native language of Mexico)
Our Lady of Fatime spoke to the children in Portuguese
Our Lady of Lourdes spoke to Bernadette in French
Also when we read about the day of Pentecostes in the upper room the “gift of tongues” is displayed as the Apostles preaching seemingly in their native language and there were people from foreign lands and each heard the message in their own language. (Not that they were babbling jibberish)
Someone there needed to hear the message from Jesus (the Gospel) and heard it in his/her own language.
By the way there is another example of this gift in St Anthony of Padua when he visited the Pope and the cardinals reunited in consistory
So Babel was not reversed (It would require all people to understand Aramaic)
Nope the Holy Spirit allows the message to be delivered in the recipient’s own language.
No Pope EVER stated that “latin” was to be imposed on all the faithfull. The Eastern Church which IS a part albeit separated of the Chatolicos uses greek and so our brothers from the Eastern churches that are in communion with the Pope use their own languages.
The real issue rests with the latin Rite Church of Rome, She has been just too succesful in evangelization and as a result She is present in every continent which has “forced” her to adopt other “vernaculars” in order to carry our Her mission.
Latin IS the official language of the Catholic Church Latin Rite and that of Official Church Documents. There is NO dispute there whatsoever for the very good reasons you enumerated.
But that does NOT forbid Her in choosing the best method to reach the faithfull.
Peace
