In 1962, two of his students, Raymond and Rosemary Buckland (religious names: Lady Rowen and Robat), emigrated to the United States and began teaching Gardnerian Witchcraft here. At the same time, other groups of people became interested through reading books by Gardner and others. Many covens were spontaneously formed, using rituals created from a combination of research and individual inspiration. These self-created covens are today regarded as just as valid as those who can trace a "lineage" of teaching back to England.

In 1975, a very diverse group of covens who wanted to secure the legal protections and benefits of church status formed Covenant of the Goddess (CoG), which is incorporated in the State of California and recognized by the Internal Revenue Service. CoG does not represent all, or even a majority of Wiccans. A coven or an individual need not be affiliated with CoG in order to validly practice the religion. But CoG is the largest single public Wiccan organization, and it is cross-Traditional (i.e. non-denominational).

Covens can be of mixed gender, or all female or male, depending on the preferences of the members. Every initiate is considered to be a priestess or priest. Most covens are small. Thirteen is the traditional maximum number of members, although not an absolute limit. At that size covens form a close bond, so Wiccans in the military are likely to maintain a strong affiliation with their covens back home. There are many distinct "Traditions" of Wicca, just as there are many denominations within Christianity.

The spectrum of Wiccan practice can be described as ranging from "traditional" to "eclectic," with Traditions, covens and individuals fitting anywhere within that range. A typical difference would be that more traditional groups would tend to follow a set liturgy, whereas eclectic groups would emphasize immediate inspiration in worship. These distinctions are not particularly important to the military chaplain, since it is unlikely that enough members of any one Tradition would be at the same base.

Worship circles at military facilities are likely to be ad-hoc cross-Traditional groups, working out compromise styles of worship for themselves and constantly adapting them to a changing membership. Therefore, the lack of strict adherence to the patterns of any one Tradition is not an indicator of invalidity. While many Wiccans meet in a coven, there are also a number of solitairies. These are individuals who choose to practice their faith alone. The may have been initiated in a coven or self initiated. They will join with other Wiccans to celebrate the festivals or to attend the various regional events organized by the larger community.

Some, but not all, Wiccan covens worship in the nude ("skyclad") as a sign of attunement with Nature. Most, but not all, Wiccan covens bless and share a cup of wine as part of the ritual.

Almost all Wiccans use an individual ritual knife (an "athame") to focus and direct personal energy. Covens often also have ritual swords to direct the energy of the group. These tools, like all other ritual tools, are highly personal and should never leave the possession of the owner.

Other commonly used ritual tools include a bowl of water, a bowl of salt, a censer with incense, a disk with symbols engraved on it (a "pentacle"), statues or artwork representing the Goddess and God, and candles. Most groups will bless and share bread or cookies along with the wine. All of these items are used in individual, private worship as well as in congregate rituals.

None.

It is desirable for a Wiccan priest or priestess to be present at the time of death, but not strictly necessary. If not possible, the best assistance would be to make the member as comfortable as possible, listen to whatever they have to say, honor any possible requests, and otherwise leave them as quiet and private as possible.
