Six books date from one year (7)
I believe the answer is:
vintage
'one year' is the definition.
(thesaurus)
'six books date' is the wordplay.
'six' becomes 'vi' ('vi' can be a synonym of 'six').
'books' becomes 'nt' (New Testament).
'date' becomes 'age'.
'vi'+'nt'+'age'='VINTAGE'
'from' is the link.
(Other definitions for vintage that I've seen before include "Grape harvest" , "Wine of a particular year" , "High quality wine" , "Good quality (wine)" , "Old" .)
