Scripture worthily translated (4,4)
I believe the answer is:
holy writ
'scripture' is the definition.
('Holy Writ' can be a synonym of 'scripture')
'worthily translated' is the wordplay.
'translated' is an anagram indicator.
'worthily' is an anagram of 'HOLY WRIT'.
(Other definitions for holy writ that I've seen before include "Good Book" , "Scripture" , "Scriptures" , "The Bible, in other words" , "Sacred writings" .)
