New convert (8)
I believe the answer is:
neophyte
'new convert' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for neophyte that I've seen before include "Reformed character" , "Apprentice; newcomer to a religion, job, society, etc..." , "raw recruit" , "Pet honey for a religious novice" , "Recent convert" .)
