A book written in the early 1800's, La Sorcière gives us an insight into thinking of that time period concerning where the power of witches comes from. Although most contemporary witches will deny the presence of Satan or demons as their power source, the thinking of the Christian church would probably agree with what this text says. It is accepted that witches do not generally accept Satan as any kind of master or lord and each witch has his or her own theology that describes their beliefs. This book however seeks to quash all those pagan ideas and gives credit to where the original author thinks it is due.
