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' means one lot of letters goes inside another.
'bishop' becomes 'B' (chess abbreviation).
'bile' enclosing 'b' is 'BIBLE'.
'revealing' is the link.
(Other definitions for bible that I've seen before include "reliable work" , "It contains scriptures" , "Book for someone swearing?" , "Holy books" , "Authoritative source" .)
