Command from religious fraternity (5)
I believe the answer is:
order
I believe this clue is a double definition.
'command' is the first definition.
(I know this)
'religious fraternity' is the second definition.
(I've seen this before)
'from' is the link.
(Other definitions for order that I've seen before include "kind > direction" , "Annual film award (5)" , "Directive or society" , "Religious fraternity" , "architectural style" .)
