OK, firstly, a slight correction - Trampus, there's a slight error in the quote. "Do what you will is the whole of the law" is the creed of the Church of Satan, and puts no restraint on its members beyond their own self-interest. "An it harm none, do what you will" is the traditional Wiccan creed, which is a fairly different thing - Do what you will as long as you harm no-one. Taken together with the law of threefold return, that says whatever you put out into the world - harm or benefit - will come back to you three times stronger - it's an effecttive, pretty disciplined line to walk.\n\nNow, to the question: yes, you can follow your Wiccan path and believe in a single god, including the one you grew up with. There are Wiccans who dedicate themselves to single gods in various systems, from Norse and Celtic to Egyptian and Christian. The one defining characteristic of Wicca is its open-mindedness - if any path helps you to be a positive, respectful influence on the planet it's pretty much fine with most Wiccans. Blessed be, and enjoy the journey you are on.
