One question I've gotten a lot is, "Can you be a Christian and a Wiccan?", or "Can you be a Christian and a Witch?". My answers to these questions are as follows:

Wicca is a religion, first and foremost, as is Christianity. So while you might hold some tenets or philosophies of Wiccan belief, if you are a Christian, you are not a Wiccan.

However, I've met Christian Witches, and even a Jewish Witch, for that matter. As Witchcraft is not a religion but rather the practice of magic, you can certainly be a Christian Witch. You'll be at odds with the Church. Christ, from all I know of Him, will probably understand. Many Christian Witches use Christ as a source of inspiration and as a figure to ask aid from. If that's something you think you may want to pursue, I lost my only link to a Jew-Witch, but if you'd like to talk to one, I can refer you to my favorite Pagan forum--someone there will probably be able to help you.
