Position bronze in southern church (6)
I believe the answer is:
stance
'position' is the definition.
(stance is a kind of position)
'bronze in southern church' is the wordplay.
'bronze' becomes 'tan' (both can mean to get a sun tan).
'in' indicates putting letters inside.
'southern' becomes 's' (abbreviation).
'church' becomes 'ce' (abbreviation for Church of England).
's'+'ce'='sce'
'tan' going within 'sce' is 'STANCE'.
(Other definitions for stance that I've seen before include "One's physical or mental attitude" , "Posture; viewpoint" , "Attitude, point of view" , "Batsman's position" , "Posture assumed" .)
