Angels in Wicca

I have seen the use of angels in some Wicca books that I am reading, specifically Uriel, Raphael, Michael, and Gabriel. All of these are angels from the Christian bible.

My question is, aren't these representations of the Christian pantheon? If so, if you acknowledge these beings from the Christian pantheon and call upon them are you not acknowledging all deities from that same pantheon? In particular Satan?

Is this an example of Christo-paganism? Having been raised loosely Christian, I love the fact that Wicca in general does not acknowledge Satan as a Deity however seeing the use of Christian angels brings about some confusion for me.

Thanks for the clarification.
