Ahh Thank you!
I define traditional witchcraft three main ways:
1) A lineage of witchcraft handed down through training and/or initiation over several hundred years or more through the cunning, guild, lodge, ceremonial, family, seer, and/or coven traditions or even ancestral memory, reincarnation, or past life memories.
2) A revival of folk magic forms from several hundred years ago or more. These can be expressed as secular, pagan revival or reconstruction, or dual observance/heretical systems.
3) A modern form of witchcraft that is usually secular, and created in opposition to mainstream forms of popular witchcraft. Decidedly non-wiccan. These forms oppose the use of the three fold law, terminology like blessed be, and the harm none rede as they see it promoted by popular wicca/witchcraft.
My personal traditional witchcraft is type 2. Although I wouldn’t turn down the right opportunity to join into type 1.
