Possibly holy commands? (6)

I believe the answer is:

orders

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

'commands?' is the definition.
(I know this)

I can't explain the rest of the clue.

(Other definitions for orders that I've seen before include "Commands these priests and nuns?" , "Dictates, commands" , "Demands" , "Dictates, decrees" , "books" .)

I've seen this clue in the Evening Standard.
