Quote from an old religious pamphlet (7)
I believe the answer is:
extract
'quote' is the definition.
(thesaurus)
'an old religious pamphlet' is the wordplay.
'an old' becomes 'ex' (prefix meaning former or onetime).
'religious pamphlet' becomes 'tract' (tract is a type of pamphlet).
'ex'+'tract'='EXTRACT'
'from' is the link.
(Other definitions for extract that I've seen before include "Pull or take out - maybe a tooth" , "Pluck out" , "Clipping" , "Passage selected from a larger work" , "concentrate" .)
