Just to derail this thread a bit. In my opinion there is no such thing as a Christian Wiccan. The religions are totally incompatible. They each have specific beliefs and practices that do not in any way fit together.
Wiccans not only don't believe that Jesus was their savior (which is central to Christian Biblical teachings) but Wiccans likewise believe that we are not in need of saving. Wiccans have no concept of Heaven, Hell, of of Satan.
Wicca is at its most basic a fertility cult where the energy that powers the universe is drawn from the Sacred Marriage and sexual relationship between the God and the Goddess. Those who claim to be Christian Wiccans put Mary as the Goddess and either Yahweh or Jesus as the God. That would mean, under Wiccan beliefs, that Mary is having sex with either God or with Jesus.
Just because there are some things in which Wicca and Christianity won't argue over theology doesn't mean you can jam the two religions together. What you do when you try that is neither Christianity nor Wicca. It's a horrible mishmash of both.
What I find generally is that when calls themselves a Christian Wiccan they mean they are a Christian who casts spells. That doesn't make them Wiccan at all. They might be a Christian Witch or a Christian Mage, but Christian Wiccan..not so much.
