Declare it, perhaps, in front of church (9)
I believe the answer is:
pronounce
'declare' is the definition.
(pronouncing is a kind of declaring)
'it perhaps in front of church' is the wordplay.
'it perhaps' becomes 'pronoun' ('it' is a pronoun).
'in front of' is a charade indicator (letters next to each other).
'church' becomes 'CE' (abbreviation for Church of England).
'pronoun'+'ce'='PRONOUNCE'
(Other definitions for pronounce that I've seen before include "Articulate clearly" , "Articulate - judge" , "make a declaration" , "say" , "Enunciate" .)
