Latin is the language of the Roman Catholic Church. It is fixed and stable, just as is its dogma--just as its liturgy used to be.
Still wrong. The only place Latin is the "language of the Roman Catholic Church" is in the church ADMINISTRATION. Last time I looked, the Church incuded ALL those baptized and confirmed into it, and not just the priesthood.
There is nothing magic about Latin. The only reason it is used as it is is simply tradition---nothing more, nothing less. It wasn't even the first language of the church.
Your "Latin uber alles" notions are simply wishful thinking on your part.
