Aura of saintliness (4)

I believe the answer is:

halo

(Other definitions for halo that I've seen before include "Hagiological aura featured in Christian art" , "This indicates holiness" , "Aura representing saintliness" , "Ring of saintliness" , "Luminous ring" .)

I've seen this clue in The Guardian.
