For my part, I tend to separate in my own mind Wicca from magick. I do so completely aware that this is my definition alone, one not to be forced upon others, and that there are plenty of folks—especially among the more traditional elements of the Wiccan movement—who would strongly disagree with me.
Still, for my purposes, it’s convenient to think of Wicca as a religion and magick as an entirely separate domain—the Craft. Within Wicca, there are many who honor the gods [in whatever form they deem best for themselves], revere Nature and the Earth, honor the Wheel of the Year through the various sabbats, and seek to advance themselves spiritually through understanding, study, worship, and fellowship. Within the Craft, we have a wide variety of people—some Wiccan, some not; some religious, some not; some who believe in Deity, many who don’t—who seek to shape or reshape reality through a variety of techniques, practices, and beliefs we call witchcraft and/or magic/k.
If I were to create a Venn diagram for it, I’d draw two interlocking circles side by side, a big one for magick, a smaller one for Wicca. Many, perhaps even most Wiccans, fall in the intersection of the two circles. But you don’t need to be a witch (a word I use here to mean an initiate in the Craft and a practitioner of magick) to be a Wiccan, and you don’t need to be Wiccan to practice magick. Indeed, the vast majority of magicians are NOT specifically Wiccan.
As always, though, there is no black or white here, and it’s hard to draw clear boundaries. Many, perhaps most, workers of magick see the first and greatest work as being the purification and improvement of self, a task usually placed in the category of religion. Gardnerian and Alexandrian witches would claim the name “Wicca” first applied to them, and point out that magick is an inherent part of their worship as Wiccans. (Many of them see the words “witch” and “Wiccan” as synonymous. I do not.)
Brief aside: it’s a matter of record that Gerald Gardner borrowed a great deal from the ceremonial magick of Crowley and the Golden Dawn and wove it into the ceremonies of Wicca as he presented them. Indeed, after Gardner put a lot of ceremonialism into Wicca, Dion Fortune took a lot of it out; Alexandrians, who (depending on who you believe) derived from the Gardnerians, retain more aspects of ceremonial magick in their rites than do modern Gardnerians.
Back to the main text. To muddy things further, most witches of whatever flavor will point out that magick is woven into the fabric of every aspect of our existence, while most who worship the gods will insist that magick is everywhere and in everyone in part because the gods are everywhere and in everyone, and there is no way to separate the two.
As the ranks of New Agers and pagans swell, we find more and more who embrace the Earth- and nature-loving aspects of Wicca, but who are embarrassed or put off by things magickal. Many are excited about their new way of belief and life and wish to share it with others, but, as was said earlier, want to be taken seriously and so downplay the magickal side of things. Many others have come to Wicca from Christianity and, while willing to throw off the shackles of that belief system, retain, still, a deep-seated, even subconscious mistrust or fear of anything smacking of “the occult.” (I find this a fascinating revelation, personally. As Susma Rio Sep rightly pointed out, many bedrock beliefs of Christianity—including not only the sacraments he mentioned but the concept of atonement through blood sacrifice, the descent of the Son of God into the underworld to triumph over Death, and the idea that prayer can change ordained reality—are nothing less than a belief in magick and very old occult principles.)
As ever, I’m for whatever works for the individual. I have no problem whatsoever with Wiccans who do not practice magick, or who do not even believe in it. Magick is above all an experiential process, something you quite literally have to see (or, at least, experience) to believe. I would take exception only to a non-magickal Wiccan trying to convert me away from what I believe and practice for myself.
My thoughts, for what they’re worth.
