Kind of bible used by a French cult abridged by Arabian (9)
I believe the answer is:
avuncular
'kind' is the definition.
(avuncular can mean kind or friendly)
'bible used by a french cult abridged by arabian' is the wordplay.
'bible' becomes 'av' (Authorised Version of the Bible).
'used by' means one lot of letters go next to another.
'a french' becomes 'un' ('a' in French).
'abridged' means to remove the last letter.
'by arabian' becomes 'ar' (abbreviation in Chambers. I am not sure about the 'by' bit.).
'cult' with its final letter taken away is 'cul'.
'av'+'un'+'cul'+'ar'='AVUNCULAR'
'of' is the link.
(Other definitions for avuncular that I've seen before include "Of an uncle - friendly" , "Kind and indulgent" , "Genial" , "Kind and friendly, like Remus" , "Like a kindly uncle" .)
