Loose bones scattered around the church (7)
I believe the answer is:
obscene
'loose' is the definition.
(thesaurus)
'bones scattered around the church' is the wordplay.
'scattered' indicates an anagram.
'around' means one lot of letters goes inside another.
'the church' becomes 'CE' (Church of England).
'bones' anagrammed gives 'obsne'.
'obsne' enclosing 'ce' is 'OBSCENE'.
(Other definitions for obscene that I've seen before include "Shocking" , "Prurient" , "Highly offensive" , "Improper" , "X-rated" .)
