A job with laudable ends for missionary (7)
I believe the answer is:
apostle
'missionary' is the definition.
(thesaurus)
'a job with laudable ends' is the wordplay.
'job' becomes 'post' (post is a kind of job).
'with' says to put letters next to each other.
'ends' suggests removing the centre.
'laudable' with its middle taken out is 'le'.
'a'+'post'+'le'='APOSTLE'
'for' is the link.
(Other definitions for apostle that I've seen before include "eg John, Paul" , "Early Christian missionary" , "Luke or John, say" , "To lapse (anag) - ardent supporter of a cause" , "Teacher of new faith or movement" .)
