I am of a rare breed. A Christian who believes in and practices Magick. This has a tendency to piss off or scare the holy crap out of many other Christians. Some Pagans are hesitant to talk shop with a Christian when it comes to Magick, but when they realize I`m not looking to beat them with a Bible or start casting damnations, they are definitely more accepting. However, if you are Christian, Wiccan, Pagan, or any other faith, and you try to press your belief onto me, do expect a polite "Your way is not mine."
So you ask, "How can a Christian practice something forbidden by the Bible?" Is it? News to me. Though I admit when I was less educated I believed that lie also.
