Special English scripture tailored to Anglicans is something all used (5,5)
I believe the answer is:
spent force
'something all used' is the definition.
'special english scripture tailored to anglicans' is the wordplay.
'special english scripture' becomes 'spent' (I can't explain this - if you can you should believe this answer much more).
'tailored to' becomes 'for'.
'anglicans' becomes 'ce' (Church of England).
'spent'+'for'+'ce'='SPENT FORCE'
'is' is the link.
(Other definitions for spent force that I've seen before include "Has-been" , "power exhausted" .)
