2"Speak to the Israelites and say to them: 'These are my appointed feasts, the appointed feasts of the LORD, which you are to proclaim as sacred assemblies. 3"'There are six days when you may work, but the seventh day is a Sabbath of rest, a day of sacred assembly. You are not to do any work; wherever you live, it is a Sabbath to the LORD. (NIV)
There are a lot of Christians that don't follow their own Bible, they pick, choose, and switch it around to suit their needs. Don't feel bad, and don't let them tell you what you can and can't do. I find that, when I was a "Christian Witch" It was much easier to just tell people I was full on Pagan, than it was to explain my belief set, which, I would like to make it known, has changed.
