I'm a little stuck... Click here to teach me more about this clue!

'minister' is the definition.
(a religious minister)

I can't explain the rest of the clue.

(Other definitions for vicar that I've seen before include "Minister" , "Serviceman" , "Member of the clergy" , "Man (or woman) of the cloth" , "Goldsmith novel ''The . . . . . of Wakefield'' (5)" .)

I've seen this clue in The Daily Express.
