Christianity/magic, dnt know. Options

hello. i want to make sure about one thing.
i dont know. i m not saying no/yes to this religion.
but id like to hear your thaughts about Christianity+magic.

The Bible contains many direct and unambiguous proscriptions against most kinds of magic. (In Deuteronomy and Exodus; in the story of the Witch of Endor in the Second Book of Samuel; and at various places in the New Testament - I can't give chapter and verse as my concordance isn't to hand, but I'd be quite happy to look them up later.)

And most practicing Catholics would be rather shocked at the notion that they are summoning spirits during the Mass. Christians believe that God is omnipresent; and the idea of a mortal human commanding Him to appear would be considered blasphemous by many. The purpose of the ceremony of the Mass is in some ways the direct opposite of an act of Ceremonial Magick; God is believed to be already present; the ritual is used to open the hearts and minds of the participants in order that they may in some sense percieve His presence.

That said, there are many Christians practicing magick without an apparent conflict of belief. This is especially true in Ceremonial magic, and those branches which deal with hierachies of angels. I'm no theologian, and perhaps someone better versed in Scripture will be able to correct me, but I think this may have something to do with the fact that all the Bible prohibitions seem to relate to thaumaturgy rather than theurgy?
