Early Christian (7)
I believe the answer is:
apostle
'early christian' is the definition.
(follower of Jesus)
This is all the clue.
(Other definitions for apostle that I've seen before include "Preacher of the gospel" , "Disciple of Jesus Christ" , "Champion - one of twelve" , "Leaps to find religious follower" , "Originally, one sent to preach the gospel" .)
