Evil in sacred Bible is beyond words (13)

I believe the answer is:

indescribable

'beyond words' is the definition.
(something indescribable can't be put into words)

'evil in sacred bible' is the wordplay.
'evil' indicates anagramming the letters.
'in'+'sacred'+'bible'='insacredbible'
'insacredbible' is an anagram of 'INDESCRIBABLE'.

'is' acts as a link.

(Another definition for indescribable that I've seen is " Defeating words".)

I've seen this clue in The Times.
