230. It does need to be known, though, that angels have absolutely no power on their own, but that all the power they have comes from the Lord. Further, they are powers to the extent that they recognize this fact. Any of them who believe that their power comes from themselves immediately become so weak that they cannot resist even a single evil spirit. This is why angels take absolutely no credit to themselves and turn down any praise or admiration for anything they have done, but attribute it all to the Lord.
