Edge into church for sin (5)
I believe the answer is:
crime
'for sin' is the definition.
(thesaurus)
'edge into church' is the wordplay.
'edge' becomes 'rim' (rim is a kind of edge).
'into' is an insertion indicator.
'church' becomes 'CE' (abbreviation for Church of England).
'rim' placed inside 'ce' is 'CRIME'.
(Other definitions for crime that I've seen before include "Lawbreaking" , "Felony" , "Social problem" , "Illegal activity" , "Illegal deed" .)
