Ok another question, what exactly does Judaism teach about angels?
There have been, unsurprisingly I'm sure, many opinions as to what angels are. And the main stream of the tradition has generally held that there are several kinds of angel, each with apparently different measures of individuality, durability, authority, and so forth.
Some angels are said to exist purely in the spiritual plane surrounding God's inmost presence. Some are said to be capable of existing in both the spiritual and the physical, if they are given a reason to take physical shape. Some are created apparently for just one purpose, and once that it fulfilled, they cease to be. Others remain and serve many purposes. And of those, it seems that some are what we might call "drones," serving simple metaphysical purposes only, and not apparently invested with much persona, while others seem to be capable of complex thought, action, and are said to be given certain measures of functional authority, either over other angels, or to guide certain aspects of the world as overseers or viceregents, as it were.
They were never seen as being either sweet and cuddly winged babies, or handsome blond guys with wings, but in their own forms, were beings that appeared to human eyes as fantastical creatures embodying mystical and mythopoeic concepts, often of strange and fearsome aspect. Regarding the sort that are sometimes held to have been sent to our world in order to interact with people, when physicalized, such angels are said to resemble normal human beings, although certain people seem to have been sometimes able to recognize something about them that marked them as spiritual beings-- although no one can seem to agree on what such a feature might have been.
The one thing that pretty much all mainstream teachings about angels agree on is that they have no free will.
Granted, these are all traditional mainstream beliefs, and there have been other beliefs that never made it into the main stream. Certain Kabbalistic schools hold other opinions, also, especially Lurianic Kabbalah, which tends to prefer a universe with much more impersonal metaphysics. And I believe the Maimonidean rationalists of the middle ages considered angels to be entirely aphysical creatures constructed of agglomerated philsophical intelligibles.
And, of course, many non-Orthodox Jews today don't believe in literal angels at all.
