Too much question for a simple answer. Believes that you are powerful in your own right. That you are a beautiful being (righteous). The first commandement is: Harm none, then do as you will.
A far more sane, loving, and just religion than Christianity. You see, they believe in doing unto others as they want others to do unto them. They believe in loving those whom others would call an enemy. They believe that when Jesus said that you have the power to move a mountain into the sea, he wasn't lying. They believe in "honesty always". They believe that women are of value in our world.
Actually, if you throw everything out of the Bible except most of the words allegedly spoken by Jesus, you will have the practices of a Wiccan. Christians don't recognize this, of course, because Christians follow the teachings of Paul who didn't particularly like Jesus' message.
