I believe the answer is:

emmanuel

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

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

I don't understand the remainder of the clue.

(Other definitions for emmanuel that I've seen before include "Lame menu (anag) - Cambridge college" , "Man" , "The Messiah" , "Boy" , "Messiah's name (Is. 7.14)" .)

I've seen this clue in The Independent.
