Miraculous event which is taken for granted (10)

I believe the answer is:

assumption

I believe this clue is a double definition.

'miraculous event' is the first definition.
(Assumption of Mary to Heaven)

'which is taken for granted' is the second definition.

(Other definitions for assumption that I've seen before include "Church festival" , "Belief" , "taken for granted" , "Claim" , "Supposition" .)

I've seen this clue in The Times.
