Maybe you should go to church to ordain (9)
I believe the answer is:
pronounce
'ordain' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for pronounce that I've seen before include "say" , "Articulate - judge" , "Enunciate" , "make a declaration" , "Articulate in a certain way" .)
