What is Wicca?
Wicca is one of the most influential traditions of modern Paganism. Also known by the name Witchcraft, it began to emerge publicly in its modern form in the late 1940's. It is an initiatory path, a mystery tradition that guides its initiates to a deep communion with the powers of Nature and of the human psyche, leading to a spiritual transformation of the self. Women who follow this path are initiated as Priestesses and men are initiated as Priests.
Wicca is sometimes called the Craft of the Wise, or, more commonly, the Craft.
Those wishing to be initiated to certain traditions must be at least 18 years of age. Wicca does not seek converts and initiation is never offered. Initiation must be asked for and is only given to those who have proved themselves suitable. It is traditional to wait a year and a day before being accepted into the Craft, although in practice this varies.
In Britain, there are a number of Craft traditions: Gardnerian, Alexandrian, Traditional, Hereditary (Family), Dianic and Hedgewitch. In other countries, other traditions have evolved to reflect their own culture. Gardnerians claim lineage from Gerald Gardner, who was most responsible for the revival of the modern Craft. Alexandrians descend from Alex and Maxine Sanders, who developed Gardner's ideas. Traditionalists claim their methods pre-date the modern revival and have been passed down from generation to generation. Hereditaries claim their traditions have been passed on by particular families through relations of blood and marriage. Dianic craft is based on feminist principles and Hedgewitches follow a more solitary path.
For some practitioners of the Craft, Witchcraft and Wicca are seen as two distinct paths, for others, the boundaries between the two are more blurred. Certainly, the word "Wicca" is less evocative and emotive than "Witchcraft" but whatever their perceived differences, they both share the same commonality in their beliefs and practises.
Witches celebrate eight seasonal festivals called Sabbats. Craft rituals, like all Pagan rites, are often conducted out of doors and involve simple rites to celebrate the seasons and the gift of life. Craft ritual is a means of contacting the Divine beyond our individual lives, but also a way of understanding our inner psyche and contacting the Divine within.
Witchcraft is a path of magic and love, the movement of a deep poetry of the soul, a sharing and joining with the mysteries of Nature and the Old Gods.
