Singular belief in homes I'm not shifting (10)

I believe the answer is:

monotheism

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

'singular belief' is the definition.
'monotheism' can be an answer for 'belief' (monotheism is a kind of belief). I am unsure of the 'singular' bit.

'homes i'm not shifting' is the wordplay.
'shifting' is an anagram indicator.
'homes'+'im'+'not'='homesimnot'
'homesimnot' with letters rearranged gives 'MONOTHEISM'.

'in' acts as a link.

Can you help me to learn more?

(Another definition for monotheism that I've seen is " Belief in only one God".)

I've seen this clue in The Daily Express.
