Wiccan ritual is worked inside a circle marked out at the start and dissolved at the end, the space itself treated as the temple. The quarters are greeted, the Goddess and God invoked, the working done, and food and drink shared before the circle is closed. Sabbats, the eight festivals of the Wheel of the Year, mark the solar round: the solstices and equinoxes together with Samhain, Imbolc, Beltane and Lughnasadh. Esbats are usually held at the full moon.
The two deities are typically understood as a Goddess associated with the moon, the earth and the cycle of life, and a Horned God associated with the sun, the wild and the hunt. Traditions differ widely on whether these are literal persons, two faces of one divinity, or archetypes, and Wicca has no creed that settles the question.
Initiatory lines descending from Gardner and from Alex Sanders work in three degrees and require an initiator. Membership is by invitation, covens are small, and a Book of Shadows is copied by hand from initiator to initiate. The Great Rite, the ritual union of Goddess and God, is normally performed symbolically with blade and cup rather than in the flesh. Some lines work skyclad, meaning naked; others do not.
Two ethical formulas circulate widely. The Wiccan Rede, in the couplet "an it harm none, do what ye will", was published in that form only in the 1970s and has no earlier attestation. The Threefold Law holds that what is sent out returns magnified. Neither is binding doctrine, and Wiccan writers argue over both.
There is no scripture, no clergy above the coven, and no central authority of any kind.
