Secular — blasphemous (7)
I believe the answer is:
profane
I believe this clue is a double definition.
'secular' is the first definition.
(I know that secular can be written as profane)
'blasphemous' is the second definition.
(I know that blasphemous can be written as profane)
(Other definitions for profane that I've seen before include "Blasphemous, irreligious" , "vulgar" , "Secular; obscene" , "Unholy" , "improper use" .)
