Modern Witchcraft
Witchcraft is a pagan religion. Pagan religions worship multiple deities rather than a single god. Paganism is one of the oldest religions and includes all religions that are not Christian, Muslim or Jewish, meaning Paganism includes the Hindu, Buddhist, Taoist, Confucian and American Indian religions as well as all other nature-oriented religions. According to the 1998 Cambridge Fact Finder, Paganism accounts for 50 percent of all religions.
The word "Pagan" actually stems from the Latin Pagini or Paganus, words meaning "hearth" or "home dweller" or, more simply, "country person" -- those labeled as Pagans were considered inferior to those living in cities. It didn't, however, mean those people were "bad." It wasn't until the 1450s that fear of witchcraft became more prevalent, and people began associating witchcraft and paganism with devil worship, evil hexes and spells.
Types of Witchcraft
There are many types of witchcraft, many of which overlap and all of which can be defined in different ways by different people, but here are some rough guidelines for their designations:
African witchcraft: There are many types of witchcraft in Africa. The Azande of central Africa believe that witchcraft causes all types of misfortune. The "gift" of witchcraft, known as mangu, is passed from parent to child. Those possessing mangu aren't even aware of it and perform magick unconsciously while they sleep.
Appalachian folk magic: Those who practice witchcraft in the Appalachian mountains see good and evil as two distinct forces that are led by the Christian God and Devil, respectively. They believe there are certain conditions that their magick cannot cure. They also believe that witches are blessed with paranormal powers and can perform powerful magick that can be used for either good or evil purposes. They look to nature for omens and portents of the future.
Green witchcraft: A Green witch is very similar to a Kitchen/Cottage witch (see below) with the exception that the Green witch practices in the fields and forest in order to be closer to the Divine spirit. The Green witch makes his or her own tools from accessible materials from outdoors.
Hedge witchcraft: A Hedge witch is not part of a group or coven. This witch practices magick alone and works more with the green arts, herbal cures and spells. In the early days, Hedge witches were local wise men or women who cured illnesses and gave advice. They can be of any religion and are considered traditional witches (see below).
Hereditary witchcraft: Hereditary witches believe in "gifts" of the craft that are with a witch from birth, having been passed from generations before.
Kitchen/Cottage witchcraft: A Kitchen witch, or Cottage witch, practices magick around the hearth and home. The home is a sacred place, and the use of herbs is used often to bring protection, prosperity and healing. Kitchen witches often follow more than one path of witchcraft.
Pennsylvania Dutch hexcraft or "Pow-wow": When the Germans first arrived in Pennsylvania, Native Americans were there, so the term "pow-wow" to describe this practice may come from observations of Indian gatherings. Pow-wowing includes charms and incantations dating back to the Middle Ages, as well as elements borrowed from the Jewish Kabbalah and Christian Bible. Pow-wowing focuses on healing illnesses, protecting livestock, finding love or casting or removing hexes. Pow-wowers consider themselves to be Christians endowed with supernatural powers.
Traditional witchcraft: Traditional witchcraft often follows science, history and the arts as its foundation. While sharing the same respect for nature as the Wiccan witch (see below), traditional witches do not worship nature nor the god or goddess of Wicca. They contact spirits that are part of an unseen spirit world during rituals. Magick is more practical than ceremonial and focuses greatly on herbs and potions. This sect of witchcraft also has no law of harming none, but does believe in responsibility and honor. Hexes and curses, therefore, can be used in self-defense or for other types of protection.
Wicca: Wicca is one of the modern Pagan religions that worships the Earth and nature, and it is only about 60 years old. It was created in the 1940s and '50s by Gerald Gardner. Gardner defined witchcraft as a positive and life-affirming religion that includes divination, herblore, magic and psychic abilities. Wiccans take an oath to do no harm with their magick.
