Approach current church with sons (6)
I believe the answer is:
access
'approach' is the definition.
(synonyms)
'current church with sons' is the wordplay.
'current' becomes 'ac' (alternating current).
'church' becomes 'CE' (abbreviation for Church of England).
'with' is a charade indicator (letters next to each other).
'sons' becomes 'ss' (genealogical abbreviation for son written twice).
'ac'+'ce'+'ss'='ACCESS'
(Other definitions for access that I've seen before include "Means, or right, of approach" , "Means of approach or entry" , "A way of approaching" , "Entrance or passage" , "Retrieve, say data stored in computer" .)
