The attitude of a man going to church (6)
I believe the answer is:
stance
'the attitude' is the definition.
(stance is a kind of attitude)
'a man going to church' is the wordplay.
'a man' becomes 'stan' ().
'going to' is a charade indicator (letters next to each other).
'church' becomes 'CE' (abbreviation for Church of England).
'stan'+'ce'='STANCE'
'of' acts as a link.
(Other definitions for stance that I've seen before include "Golfer's position for making stroke" , "Attitude - taken by a golfer?" , "position when batting" , "Position, viewpoint" , "Bearing" .)
