Wickedness coming to church subsequently (5)
I believe the answer is:
since
'subsequently' is the definition.
(I've seen this in another clue)
'wickedness coming to church' is the wordplay.
'wickedness' becomes 'sin' (synonyms).
'coming to' is a charade indicator (letters next to each other).
'church' becomes 'CE' (Church of England).
'sin'+'ce'='SINCE'
(Other definitions for since that I've seen before include "From that time one" , "Seeing that" , "in the past" , "Because; ago" .)
