Regarding: "..."...the use of the Latin language is to be preserved in the Latin rites.""
- Yes and correct ... for the holy church of Rome.
- Elsewhere, other languages were and are used: Aramaic, Slavonic, Irish, Copt and so on.
- The catholic church which is in union and communion with the archbishop of Rome made a serious mistake from 1492 to 1962 by taking the Roman Missal as a latin book to other countries and not adopting and adapting it to the needs of the people.
- Trent acknowledge that the liturgies could contain the vernacular (pastoral explanations by the presbyter), though it never went very far with it. Trent also did insist that the ancient liturgies of each church (those not following the liturgies as in Rome, in many cases not with the Latin language) must be retained.
- Luckily Vatican II in the spirit of continuity with Trent resolved and moved forward the occasions for the vernacular liturgies throughout the world.
