It is "by the educated class throughout Christiandom", which is the reference I was responding to. Obviously the "average" lay Catholic from a non-English speaking country wouldn't understand English.
>> for better or worse its meaning is in a constant state of flux. <<
So was Latin during the 1500 years it was use as the "default" language. Vulgar Latin that was used and understood by the masses is quite different from Classical Latin that was used by the educated and aristocrats writing down religious texts.
There is no equivalent "Classical English" used by the educated and aristocrats for any purpose. Indeed, is seems increasingly that our "educated" and "aristocrat" class drive the changes in meaning of the English language, and do so for nefarious purposes.
Gonna don your "gay apparel" this Yuletide? No? Didn't think so ... and it wasn't us common folk that poisoned the word "gay".
Not sure I really have a dog in this Latin fight, but I do sympathize with the Latin-lovers.
