Love is integral to religious sect, one helping us see the light? (7)
I believe the answer is:
oculist
'one helping us see the light?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'love is integral to religious sect' is the wordplay.
I cannot really understand how this works, but
'love' could be 'o' (In tennis, 'love' means 'zero') and 'o' is found within the answer.
'is' is within the answer.
'sect' could be 'cult' (I've seen this in other clues) and 'cult' is found in the leftover letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for oculist that I've seen before include "Specialist in defects and diseases of the eye" , "Person of vision" , "One specialising in eye diseases" , "Former name for an ophthalmologist" , "Treater of eyes" .)
