Irreverence, ungodliness (7)
I believe the answer is:
impiety
I believe this clue is a double definition.
'irreverence' is the first definition.
(impiety is a kind of irreverence)
'ungodliness' is the second definition.

(Other definitions for impiety that I've seen before include "godlessness" , "Irreligion" , "sacrilege" , "Irreverence, profanity" , "Lack of reverence" .)
