Stanford University Press. He returned to San Francisco State in 1966, where he completed a master's degree in creative writing in 1968. From then, until 1973, Kelly worked for publisher
W. H. Freeman and Company. At the end of 1973, he left W. H. Freeman to begin working on a Ph.D. at the
Graduate Theological Union (GTU) in Berkeley. He also started his own business as a consulting editor at this time. as well as a manuscript titled “Ye Bok of ye Art Magical” from Gardner's former
Museum of Witchcraft, then owned by
Ripley's, now owned by the
Wiccan Church of Canada. He hoped to use these materials to reconstruct a history of how Gardner founded modern
Wicca. The resulting manuscript was used to satisfy his comprehensive examination topic in Sociology of Religion for his doctorate program at GTU. In 1976, Kelly sought help from
Alcoholics Anonymous. He withdrew from participation in the Neo-Pagan community in 1977 and became a practicing Roman Catholic from 1978 until 1987. However, as Kelly explained in a 2006 interview with Lisa Harris of
Widdershins, he "never stopped being a witch; I just stopped practicing for a while." Kelly received a Ph.D. in Theology from GTU in 1980. For the next eight years, he taught at schools in the San Francisco Bay area, including the
University of San Francisco and Holy Family College. He was active in scholarly professional societies, and from 1987 to 1990 co-chaired the steering committee for the
American Academy of Religion's Group on New Religious Movements. Llewellyn published Kelly's previously rejected research as
Crafting the Art of Magic in 1991, revised and expanded as
Inventing Witchcraft in 2007. After moving to Seattle, Washington, in 1997, Kelly worked for several companies related to

Lakewood, Washington, in 2001. In 2008, Kelly and his family moved to New Orleans, where he taught for
