Take back bible class pamphlet (7)
I believe the answer is:
retract
'take back' is the definition.
(as in retracting a statement)
'bible class pamphlet' is the wordplay.
'bible class' becomes 're' (Religious Education).
'pamphlet' becomes 'tract' (synonyms).
're'+'tract'='RETRACT'
(Other definitions for retract that I've seen before include "Withdraw one's statement" , "Withdraw, take back" , "Revoke" , "Reverse" , "Abjure" .)
