I totally agree that there's a problem with "Grand Inquisitor" -- I might be inclined to slow down or suspend my contributions to the Monastery if I were getting close to assuming that title (not like that's going to happen any time soon, but still), because for me the connotations of the term are heinous, and I'd be embarrassed to see it next to my name.
I'm not sure about "Primate" though -- that term has a whole 'nuther problem of connotations... And "Evangelist"? Ick. "Beadle" is actually kinda cute (like, I'm picturing floppy ears, short legs and a cold, wet nose...)
I think if we're going to put a "Pilgrim" above a "Monk" (which I'm perfectly willing to accept), why not set a "Prelate" above a "Cardinal"? (According to my dictionary, "prelate" is simply a vague term for any high-ranking church official, but perhaps no one would be offended by "redefining" the term this way.)
Or better yet (as suggested in one strong dissent, it would probably be just as well to remove this extra level completely and move the higher levels down a notch -- it's currently unoccupied, so what difference would it make, really?
