Non-religious (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
secular
'non-religious' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for secular that I've seen before include "without religion" , "Ignoring God" , "Clear us, not being involved in religion" , "Concerning the laity" , "Not connected with religious matters" .)
