Makes for church with son (6)
I believe the answer is:
forces
'makes' is the definition.
(forcing is a kind of making)
'for church with son' is the wordplay.
'church' becomes 'ce' (abbreviation for Church of England).
'with' says to put letters next to each other.
'son' becomes 's' (genealogical abbreviation for son).
'for'+'ce'+'s'='FORCES'
(Other definitions for forces that I've seen before include "Compels or inflicts" , "Influences" , "Compels, obliges" , "soldiers" , "Compels someone to do something" .)
