Prayer from a money supplier to America (7)

I believe the answer is:

angelus

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

'prayer' is the definition.
(Angelus is an example)

'a money supplier to america' is the wordplay.
'a money supplier' becomes 'angel' (I can't explain this - if you can you should believe this answer much more).
'to america' becomes 'US' (United States).
'angel'+'us'='ANGELUS'

'from' is the link.

Can you help me to learn more?

(Other definitions for angelus that I've seen before include "Midday prayer" , "Thrice daily prayer of Roman Catholics" , "Church bell" , "(Bell calling Catholics to) prayer" , "RC prayer, its bell" .)

I've seen this clue in The Globe and Mail.
