they actually do not even have to 'pose' because they are angels.

Matthew 25:41
Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:

Revelation 12:9
And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

That's from the KJV btw.. everything I have ever quoted from the bible is KJV. If you cannot find those passages in your version of it then some pages in your bible have been altered from the original.
