[Wonder Warthog]

"Translation is never exact; it's not a bad idea to have a standard from which translations are made that's not subject to peioration, melioration, regional differences, new meanings through current slang, etc."

All true, and good practical reasons for the Church HIERARCHY to continue to use it. But that is simply a matter of convenience, and not one of Church dogma or some kind of "sacredness" on the part of Latin.

Each of those reasons applies also to the liturgy -- unless you want to retranslate every few years (hoping you didn't miss any unfortunate linguistic development in the meantime!).
