Social creature has a book (3)

I believe the answer is:

ant

I'm a little stuck... Click here to teach me more about this clue!

'social creature' is the definition.
'ant' can be an answer for 'creature' (ant is a kind of animal). I am unsure of the 'social' bit.

'a book' is the wordplay.
'book' becomes 'NT' (New Testament).
'a'+'nt'='ANT'

'has' acts as a link.

Can you help me to learn more?

(Other definitions for ant that I've seen before include "Proverbially hard-working insect" , "Social worker" , "Six-footer" , "Hill-dweller" , "Small busy insect" .)

I've seen this clue in The Mirror.
