Wise to accept Catholic anger for blasphemy (9)
I believe the answer is:
sacrilege
'blasphemy' is the definition.
('sacrilege' can be a synonym of 'blasphemy')
'wise to accept catholic anger' is the wordplay.
'wise' becomes 'sage' ('sage' can be similar in meaning to 'wise').
'to accept' indicates putting letters inside.
'catholic' becomes 'c' (abbreviation as in RC for Roman Catholic).
'anger' becomes 'rile' (I've seen this in other clues**).
'c'+'rile'='crile'
'sage' enclosing 'crile' is 'SACRILEGE'.
'for' acts as a link.
(Other definitions for sacrilege that I've seen before include "Blasphemy" , "Blasphemous behaviour" , "Misuse of something sacred" , "profanity" , "Disrespect or damage to something sacred" .)
