Extremely ancient religious piece will entice (7)
I believe the answer is:
attract
'entice' is the definition.
(I've seen this before)
'extremely ancient religious piece will' is the wordplay.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'religious piece will' becomes 'tract' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ancient' with its centre removed is 'at'.
'at'+'tract'='ATTRACT'
Can you help me to learn more?
(Other definitions for attract that I've seen before include "Exercise a magnetic influence" , "Arouse interest of" , "'Draw, charm (7)'" , "Act as a magnet" , "Exert a pull upon" .)
