Holy man keeps Jerry in place (4)
I believe the answer is:
spot
'place' is the definition.
('spot' can be a synonym of 'place')
'holy man keeps jerry' is the wordplay.
'holy man keeps' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'jerry' becomes 'pot' (slang for chamber pot).
's'+'pot'='SPOT'
'in' is the link.
(Other definitions for spot that I've seen before include "See - speckle" , "Predicament" , "Identify" , "Small mark; observe" , "Blob" .)
