What is Black magic ?

Black magic has traditionally referred to the use of supernatural powers or magic for evil and selfish purposes. With respect to the left-hand path and right-hand path dichotomy, black magic is the malicious, left-hand counterpart of benevolent white magic. In modern times, some find that the definition of "black magic" has been convoluted by people who define magic or ritualistic practices that they disapprove of as "black magic"

The influence of popular culture has allowed other practices to be drawn in under the broad banner of "black magic" including the concept of Satanism. While the invocation of demons or spirits is an accepted part of black magic, this practice is distinct from the worship or deification of such spiritual beings.

Those lines, though, continue to be blurred by the inclusion of spirit rituals from otherwise "white magicians" in compilations of work related to Satanism. John Dee's 16th century rituals, for example, were included in Anton LaVey's The Satanic Bible (1969) and so some of his practises, otherwise considered white magic, have since been associated with black magic. Dee's rituals themselves were designed to contact spirits in general and angels in particular, which he claimed to have been able to do with the assistance of colleague Edward Kelley. LaVey's Bible, however, is a "complete contradiction" of Dee's intentions but offers the same rituals as a means of contact with evil spirits and demons. Interestingly, LaVey's Church of Satan (with LaVey's Bible at its centre), "officially denies the efficacy of occult ritual" but "affirms the subjective, psychological value of ritual practice", drawing a clear distinction between. LaVey himself was more specific:

The links and interaction between black magic and religion are many and varied. Beyond black magic's links to organised Satanism or its historical persecution by Christianity and its inquisitions, there are links between religious and black magic rituals. The Black Mass, for example, is a sacrilegious parody of the Catholic Mass. Likewise, a saining, though primarily a practice of white magic, is a Wiccan ritual analogous to a christening or baptism for an infant.

17th century priest, Étienne Guibourg, is said to have performed a series of Black Mass rituals with alleged witch Catherine Monvoisin for Madame de Montespan
