Immoral order consuming church (8)
I believe the answer is:
indecent
'immoral' is the definition.
(thesaurus)
'order consuming church' is the wordplay.
'order' becomes 'indent' (indent can mean an order or request).
'consuming' indicates putting letters inside.
'church' becomes 'CE' (Church of England).
'indent' going around 'ce' is 'INDECENT'.
(Other definitions for indecent that I've seen before include "Immodest, gross" , "Indecorous" , "blue" , "not appropriate" , "Smutty" .)
