Declaration of New Testament (9)

I believe the answer is:

statement

'declaration' is the definition.
(I've seen this before)

'new testament' is the wordplay.
'new' indicates an anagram.
'testament' anagrammed gives 'STATEMENT'.

'of' acts as a link.

(Other definitions for statement that I've seen before include "Formal account given to police" , "Document showing credits and debits" , "Proclamation" , "Assertion" , "Record of bank balance" .)

I've seen this clue in The Telegraph.
