Of a bishop (9)
I believe the answer is:
episcopal
'of a bishop' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for episcopal that I've seen before include "Relating to bishops" , "Pepsi-Cola for bishops' kind of business" , "controlled by bishop" , "To do with bishop - maybe Pepsi-Cola" , "run by bishops" .)
