I can be found in the Gospels (3)
I believe the answer is:
ego
'i' is the definition.
('I' in Latin)
'found in the gospels' is the wordplay.
'found in' indicates the answer is hidden within the clue.
'EGO' can be found hidden inside 'the gospels'.
'can be' is the link.
(Other definitions for ego that I've seen before include "One's self-image" , "Self-esteem, conceit" , "Inflated pride" , "Person's sense of self" , "Morale" .)
