You can practice whatever you want. You can practice any way you want. But from my perspective, you cannot divorce the Devil from witchcraft. The Sabbat exists to call the Devil. A witch is someone outside of society. The Adversary. They are against the power that holds sway. They are against the social norms that hold people back. They are against the control of the priests and the rich. To be a witch is to be the other, the scapegoat, the enemy. And no being in the universe serves that role better than the Devil.
If you exist culturally in the West then the Devil has always been with you. You can’t escape him. He is in your blood and your bones, and he was known to your ancestors for generations. He was not always the Faustian boogyman, though he’ll play that role too. He was the one who had dominion over the Earth and if you needed something done here, calling on Jehovah and his angelic mafia would get you no joy.
Pray to God if you like in the bright light of day. Call to your “higher” self and beg. But under the stars, next to the fire, dancing in the moonlight, that’s not God dancing with you.
I ain’t afraid of the Devil no more. The Devil is a friend of mine.
