Hostility in country church (6)
I believe the answer is:
malice
'hostility' is the definition.
(thesaurus)
'country church' is the wordplay.
'country' becomes 'Mali' (Mali is an example).
'church' becomes 'CE' (abbreviation for Church of England).
'mali'+'ce'='MALICE'
'in' acts as a link.
(Other definitions for malice that I've seen before include "Hate" , "'Ill-will, spite (6)'" , "Desire to harm others, may be aforethought" , "Bitterness" , "Spite and rancour" .)
