God would personally institute any authority on earth (i.e. Jesus). That's the flaw in several other religions that base themselves on Christianity. Mormons say the "angel maroni" came to Joe Smith and told him the book of Mormon, but it says in the Bible (I forget the coordinates right now since I'm at work) that the only way you should add to or adjust His word is if He Himself comes to you. Angels and demons are the same thing, except the demons are fallen and evil, but they have the same abilities.
