Crossword Genius

Religious folk understand about eternities (7)

Ross

I believe the answer is:

gideons

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

'religious folk' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'understand about eternities' is the wordplay.
'understand' becomes 'dig' (digging is a kind of understanding).
'about' says the letters should be written in reverse.
'eternities' becomes 'eons' (I've seen this in another clue).
'dig' backwards is 'gid'.
'gid'+'eons'='GIDEONS'

Can you help me to learn more?
