Don't hold to one's statement about a religious paper (7)
I believe the answer is:
retract
'don't hold to one's statement' is the definition.
I can't judge whether this defines the answer.
'about a religious paper' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'a religious paper' becomes 'tract' (I've seen this in another clue. I am not sure about the 'religious' bit.).
're'+'tract'='RETRACT'
Can you help me to learn more?
(Other definitions for retract that I've seen before include "Eat one's words" , "Sheathe" , "Withdraw as unjustified" , "Cancel" , "Reverse" .)
