Duty of Bede, I suspect, in ordinary northern church (9)
I believe the answer is:
obedience
'duty' is the definition.
(obedience is a kind of duty)
'bede i suspect in ordinary northern church' is the wordplay.
'suspect' indicates anagramming the letters.
'in' indicates putting letters inside.
'ordinary' becomes 'o' (abbreviation e.g. O-Levels).
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'church' becomes 'ce' (abbreviation for Church of England).
'bede'+'i'='bedei'
'bedei' is an anagram of 'bedie'.
'o'+'n'='on'
'bedie' placed inside 'on' is 'obedien'.
'obedien'+'ce'='OBEDIENCE'
'of' acts as a link.
(Other definitions for obedience that I've seen before include "Being compliant" , "special devotion" , "It is said to be the first duty of a soldier" , "Compliance with an order or law" , "Observance of the rules" .)
