Anger about bishop revealing scripture (5)
I believe the answer is:
bible
'scripture' is the definition.
(synonyms)
'anger about bishop' is the wordplay.
'anger' becomes 'bile' (I've seen this in another clue).
'about' is an insertion indicator.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'bile' placed around 'b' is 'BIBLE'.
'revealing' acts as a link.
(Other definitions for bible that I've seen before include "reliable work" , "It contains scriptures" , "Book for someone swearing?" , "Holy books" , "Authoritative source" .)
