I had occasion to ask a Catholic priest once. The question was fresh in my mind since we were just returning from a rehearsal of the Mozart Requiem and had stopped off for something to eat. One of the people in our group recognized a couple enjoying a beer and some food as being a priest and a nun. I introduced my self and asked. The nun knew no Latin and the priest struggled to recapture what little he had learned but hadn't used since the Great Changeover. He had no answer for me. It was all I could do, upon learning that neither were anywhere near fluent in Latin, to keep myself from stuttering out, "But, that means you don't have benefit of clergy."
