Short distance from born-again Christian (4)
I believe the answer is:
inch
'short distance' is the definition.
(I have seen 'Short distance' mean 'inch' so perhaps 'distance' could also mean 'inch'; 'short' asks for a short form)
'from born-again christian' is the wordplay.
'from' says the answer is hidden in the clue.
'INCH' is hidden in the letters of 'born again christian'.
(Other definitions for inch that I've seen before include "One of a 2 down in a foot" , "Move along gradually" , "Creep towards < island" , "amount of rainfall?" , "Small Scottish island" .)
