Toast is to convert non-Christians (7)

I believe the answer is:

taoists

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

'non-christians' is the definition.
I can't judge whether this defines the answer.

'toast is to convert' is the wordplay.
'to convert' is an anagram indicator (I've seen 'converts' mean this).
'toast'+'is'='toastis'
'toastis' is an anagram of 'TAOISTS'.

Can you help me to learn more?

I've seen this clue in The Times.
