Novel with moving statement, part of good book (3,9)
I believe the answer is:
new testament
'part of good book' is the definition.
('New Testament' is part of 'good book')
'novel with moving statement' is the wordplay.
'novel' becomes 'new' ('new' can be a synonym of 'novel'**).
'with' says to put letters next to each other.
'moving' indicates anagramming the letters.
'statement' with letters rearranged gives 'testament'.
'new'+'testament'='NEW TESTAMENT'
(Other definitions for new testament that I've seen before include "Canon" , "Matthew and others" , "part of desert island bookshelf?" , "collection of religious books" , "Second part of the Bible" .)
