A church member in general (8)
I believe the answer is:
catholic
This could be a double definition.
'a church' is the first definition.
(Catholic Church is an example)
'member in general' is the second definition.
'catholic' can be an answer for 'general' (I've seen this before). I'm unsure of the 'member in' bit.
Can you help me to learn more?
(Other definitions for catholic that I've seen before include "All embracing" , "Diverse" , "Chat Clio up to be Roman religion" , "Prayer" , "Eclectic" .)
