Orders Eastern beliefs back to front (6)
I believe the answer is:
decree
'front' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for decree that I've seen before include "An official order or judgement" , "Ordain" , "Edict; court order" , "Direct" , "Official order that has the force of law" .)
