One of the archangels (7)
I believe the answer is:
gabriel
'one of the archangels' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gabriel that I've seen before include "Angel of Annunciation" , "Archangel and messenger of God" , "musician" , "The angel with a trumpet" , "Chief guard of Paradise" .)
