'minister' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for chaplain that I've seen before include "man of God" , "Clergyman attached to an organisation" , "Member of clergy ministering to an organisation" , "Clergyman attached to military unit" , "Member of the clergy, in 24 ac say" .)

I've seen this clue in The Telegraph.
