Fellow takes church attitude (6)
I believe the answer is:
stance
'attitude' is the definition.
(I know that stance is a type of attitude)
'fellow takes church' is the wordplay.
'fellow' becomes 'stan' (man's name).
'takes' means one lot of letters go next to another.
'church' becomes 'CE' (abbreviation for Church of England).
'stan'+'ce'='STANCE'
(Other definitions for stance that I've seen before include "Enacts (anag)" , "Position, at the tee perhaps" , "Attitude - taken by a golfer?" , "policy" , "driver preparing to strike" .)
