Magic is seen as making miracles which is what only God is supposed to do.

No, their powers are sealed so that they don't cause any trouble for the new neighbors. All countries do this to their inhabitants as a precaution against treason. Angels don't lose their powers they just wear a vial of milk and if too much spills they return to Celestia. However it is partly as you mentioned, it's supposed to deter angels from leaving to stay with humans.

Why thank you I thought about adding Angels and Demons when I first started adding species to the Imoutoverse, but I didn't add them until after I needed more spiritual beings.
