Consecrate — order (6)
I believe the answer is:
ordain
I believe this is a double definition.
'consecrate' is the first definition.
(synonyms)
'order' is the second definition.

(Other definitions for ordain that I've seen before include "Consecrate as priest" , "Appoint - admit to holy orders" , "Appoint ceremonially to the priesthood" , "Invest with ministerial authority" , "Invest with priestly authority" .)
