Black Mass

The Black Mass is an obscene and deliberately sacrilegious parody of the Catholic Holy Mass, performed for magical, diabolical or anti-Christian purposes. It has long occupied a sinister place in the popular imagination, where it became inseparably associated with Devil worship, witchcraft, forbidden magic and the deliberate inversion of Christianity. During the centuries of the European witch hunts, inquisitors and Demonologists frequently claimed that witches and heretics celebrated obscene masses during their Sabbats, worshipping the Devil while defiling Christian symbols. Yet the historical reality is far more uncertain. Black Masses have certainly been performed at different periods, and versions continue to exist in some modern Satanic traditions, but there is little evidence that they were ever as widespread, organised or grotesque as witch hunters, sensational writers and later fiction suggested.

There has never been a single definitive Black Mass ritual. The basic principle is inversion and desecration. Elements traditionally attributed to the rite include performing the Catholic Mass, or portions of it, backwards; displaying an inverted crucifix; stepping or spitting upon the cross; stabbing or otherwise desecrating the consecrated Host; substituting urine for holy water or wine; and replacing the Host with objects such as rotten turnip slices, black leather or triangular black wafers. Black candles may replace white ones, while the celebrant may wear black vestments or robes the colour of dried blood, decorated with inverted crosses, goat heads or magical symbols.

The Black Mass derives much of its occult significance from the Catholic doctrine of transubstantiation, according to which the bread and wine of the Eucharist become the body and blood of Christ. Within the magical interpretation of the Black Mass, the priest is therefore regarded as possessing the ability to perform a genuine transformation through ritual. If sacred power can be invoked during the Holy Mass, then, according to this reasoning, that same power might be deliberately redirected towards magical, destructive or blasphemous purposes.

Magical uses of the Mass and accusations of its deliberate corruption are almost as old as Christianity itself. In the second century, Saint Irenaeus accused the Gnostic teacher Marcus of perverting Christian ritual. The Gelasian Sacramentary, dating from approximately the sixth century, contains masses intended for purposes such as weather control, fertility, protection and love divination. Masses intended to bring about the death of another person were condemned by the Council of Toledo as early as 694. Such practices became increasingly associated with forbidden magic during the Middle Ages, when the boundaries between religion, folk magic, sorcery and ritual power were often far less clearly defined than they would later become.

The Mass of Saint Secaire

One of the most infamous forms of the Black Mass was the Mass of Saint Secaire, said to have originated in medieval Gascony. Its purpose was not simply blasphemy but murder by magic. The rite was supposedly performed in order to cause an enemy to waste away slowly until death.

Montague Summers gave one of the most atmospheric descriptions of the ceremony in The History of Witchcraft and Demonology:

The mass is said upon a broken and desecrated altar in some ruined or deserted church where owls hoot and mope and bats flit through the crumbling windows, where toads spit their venom upon the sacred stone. The priest must make his way thither late, attended only by an acolyte of impure and evil life. At the first stroke of eleven he begins; the liturgy of hell is mumbled backwards, the canon said with a mow and a sneer; he ends just as midnight tolls.

The rite was said to require a triangular black Host and brackish water drawn from a well into which the corpse of an unbaptised infant had been thrown. Whether the Mass of Saint Secaire ever existed in precisely the form described is uncertain, but it became one of the most enduring examples of the imagined inversion of Catholic ritual.

The Templars, Gilles de Rais and the Medieval Black Mass

The development of the Black Mass as an organised form of alleged Devil worship coincided with the growth of the Inquisition and increasing fear of heresy and witchcraft. During the fourteenth and fifteenth centuries, accusations involving Devil’s Pacts, Sabbats and obscene parodies of Christian worship became increasingly common.

In 1307, the powerful Knights Templar were arrested and accused of conducting blasphemous rites in which Christ was renounced, the cross was spat upon or trampled, and mysterious idols were worshipped. They were also accused of worshipping the Devil in the form of a black cat. These rites were not originally described as Black Masses, and the reliability of many of the accusations remains deeply disputed, especially because confessions were extracted under torture. Nevertheless, the destruction of the Templars became permanently entangled with later legends of secret diabolical ceremonies.

In 1440, the French baron Gilles de Rais was arrested and accused of conducting Black Masses in the cellar of his castle in an attempt to obtain riches and power. He was also charged with the kidnapping, torture and murder of more than 140 children. He was convicted and executed. His crimes and alleged occult practices later became one of the darkest legends associated with ceremonial Satanism and were repeatedly revived in nineteenth and twentieth century literature.

Witchcraft and the Black Mass

During the European witch hunts, accused witches were frequently said to participate in obscene ceremonies at Sabbats in which Christian worship was inverted, the Host was desecrated, the cross defiled and the Devil himself appeared as priest. Accounts described black or red Hosts, urine used in place of sacred liquids, sexual acts, dancing, Devil’s Pacts and grotesque parodies of Christian sacraments.

Most of these descriptions came from inquisitors, Demonologists or tortured prisoners and must therefore be treated with considerable caution. Historian Jeffrey Burton Russell observed in A History of Witchcraft that:

“the black mass is unknown in historical European witchcraft. . . .”

There is no convincing evidence that the Black Mass formed an established part of historical European witchcraft. Many accusations almost certainly reflected the fears and theological expectations of the authorities rather than the practices of those being prosecuted.

The first recorded mention of a witches’ Sabbat in a trial occurred at Toulouse in 1335. By the fifteenth and sixteenth centuries, elaborate accounts circulated describing gatherings in which infants were roasted and eaten, witches kissed the Devil, participants engaged in sexual rites and obscene masses were performed. Such stories became central to the Demonological image of witchcraft, but their historical reliability remains highly doubtful.

France and the Seventeenth Century

The Black Mass reached the height of its notorious reputation in seventeenth century France, particularly during the reign of Louis XIV. At this time, grimoires, fortune-telling, ceremonial magic, poison, love magic and clandestine ritual flourished beneath the glittering surface of aristocratic society. Black Masses were said to have become fashionable among certain members of the nobility, who hired priests to conduct erotic or magical ceremonies in secret rooms and dark cellars.

One priest, Gentien le Clerc, tried at Orléans in 1614 and 1615, confessed to performing a “Devil’s mass” followed by drinking and sexual revelry. In 1647, during the Louviers Possessions, Ursuline nuns claimed that they had been bewitched and forced by chaplains to participate naked in Black Masses, trampling the Host, defiling the cross and engaging sexually with Demons.

The most notorious scandal, however, centred upon Catherine Deshayes, better known as La Voisin, a fortune-teller, poisoner and seller of love philtres who became one of the central figures in the infamous Affair of the Poisons. La Voisin employed priests to conduct magical masses for wealthy clients, among them the priest Abbé Guiborg, who was described as wearing elaborate vestments trimmed with gold and lace.

According to accusations made during the investigation, Madame de Montespan, mistress of Louis XIV, sought La Voisin’s assistance when she feared that the king’s affection was turning towards another woman. Guiborg was said to have celebrated several Black Masses over Montespan’s naked body, invoking Satan together with Beelzebub, Asmodeus and Astaroth in order to secure the king’s desire.

The most horrifying testimony claimed that children were sacrificed, their blood collected in chalices and mixed with flour for the Host. Guiborg was accused of consecrating the Host over Montespan’s body and performing extreme acts of sacrilege during the ceremony. These accounts were obtained in an atmosphere of fear, scandal and torture, and their details cannot simply be accepted as unquestioned fact.

When the scandal erupted, Louis XIV ordered the arrest of hundreds of people. Some 246 men and women were implicated, including members of the highest levels of French society. Many confessions were obtained under torture. Thirty-six commoners were executed, including La Voisin, who was burned alive in 1680, while many aristocratic defendants escaped with imprisonment or exile.

The Black Mass in Literature and the Occult Revival

By the nineteenth century, the Black Mass had become as much a creation of literature and occult imagination as a historical ritual. The Gothic fascination with Satanism, decadence and forbidden religion transformed it into a powerful symbol of spiritual rebellion and deliberate blasphemy.

Joris K. Huysmans gave the Black Mass one of its most influential literary treatments in his 1891 novel Là-bas. The novel combines the story of Gilles de Rais with contemporary rumours of Satanic rites. Its protagonist, Durtal, attends a Black Mass in a decaying former chapel filled with choking incense made from substances including henbane, datura, nightshade and myrrh. The ceremony descends into obscenity, blasphemy and sexual frenzy, culminating in what Huysmans describes as:

“a monstrous panDemonium of prostitutes and maniacs.”

Such fictional accounts strongly influenced later conceptions of Satanic ritual, helping to create a standard image of the Black Mass that would be repeated throughout twentieth century novels, occult literature and horror films.

The Hell-Fire Club has also frequently been associated with Black Masses, though surviving accounts suggest that its rites may have involved more theatrical anti-Christian mockery, sexual libertinism and heavy drinking than serious Devil worship.

Aleister Crowley and the Black Mass

Aleister Crowley was frequently accused during his lifetime of practising black magic and conducting Satanic ceremonies, yet he explicitly rejected the Black Mass. Crowley’s magical system was often anti-Christian in symbolism, but that did not make it Satanic in the conventional sense. His Gnostic Mass, for example, became an important ritual within the Ordo Templi Orientis and bears little resemblance to the popular conception of the Black Mass.

In 1933, Crowley discussed the subject in an article on black magic published in the Sunday Dispatch. His comments reveal an important distinction between genuine belief in the Eucharist and mere theatrical blasphemy:

In Paris, and even in London, there are misguided people who are abusing their priceless spiritual gifts to obtain petty and temporary advantages through these practices. The “Black Mass” is a totally different matter. I could not celebrate it if I wanted to, for I am not a consecrated priest of the Christian Church. The celebrant must be a priest, for the whole idea of the practice is to profane the Sacrament of the Eucharist. Therefore you must believe in the truth of the cult and the efficacy of its ritual.

A renegade priest gathers about him a congregation of sensation-hunters and religious fanatics; then only can the ceremonies of profanation be of extended black magical effect.

There are many ways of abusing the Sacrament. One of the best known of which is the “Mass of Saint Secaire,” the purpose of which is to cause an enemy to wither away.

At this “mass,” always held in some secret place, preferably in a disused chapel, at midnight, the priest appears in canonical robes.

But even in his robes there is some sinister change, a perversion of their symbolic sanctity. There is an altar, but the candles are of black wax. The crucifix is fixed the head downwards. The clerk to the priest is a woman, and her dress, although it seems to be a church garment, is more like a costume in a prurient revue. It has been altered to make it indecent.

The ceremony is a parody of the orthodox Mass, with blasphemous interpolations.

The priest must be careful, however, to consecrate the Host in the orthodox manner. The wine has been adulterated with magical drugs like deadly nightshade and vervain, but the priest must convert it into the blood of Christ.

The dreadful basis of the Mass is that the bread and wine have imprisoned the Deity. Then they are subjected to terrible profanations.

Indescribable

This is supposed to release the powers of evil and bring them into alliance. (It is rather the case of the mouse trying to make a friend of the cat!) In the congregational form of the Black Mass the priest, having finished his abominations—these are, quite frankly, indescribable—scatters the fragments of the Host on the floor, and the assistants scramble for the soiled fragments, the possession of which, they believe, will allow them to work their petty and malicious designs.

My most memorable personal experience of the effects of black magic occurred when I was living in Scotland. The machinations of a degraded and outcast member of the Order caused my hounds to die, my servants to become insane. The struggle lasted until the recoil of the current of hated caused the luckless sorcerer to collapse.

The explanation of its effects is that, if you believe passionately enough in your will to do something, then power to achieve it will accrue to you.

A Black Mass was reportedly performed at Crowley’s graveside following his death in 1947, adding yet another layer to the persistent association between his name and Satanism, despite his own rejection of the rite.

The Black Mass and Modern Satanism

The occult revival of the twentieth century transformed the Black Mass once again. It became an established feature of horror fiction and cinema, particularly after novels such as Dennis Wheatley’s The Devil Rides Out, published in 1934 and later filmed by Hammer in 1968. Popular culture increasingly portrayed the Black Mass as the central ceremony of every Satanic group, although actual practices varied enormously.

When Anton Szandor LaVey founded the Church of Satan in 1966, he did not initially include the traditional Black Mass among its principal rituals because he regarded it as “outmoded.” Satanism, as LaVey conceived it, was not dependent upon belief in the Christian Devil, and consequently the ritual destruction of Christian symbols had less theological significance. Nevertheless, theatrical Black Masses have sometimes been performed by Satanists as acts of parody, rebellion or social provocation.

Other Satanic or Left-Hand Path groups have incorporated versions of the Black Mass into their practices. In some traditions, the ceremony is intended to generate magical power through deliberate blasphemy, sexual ritual and the psychological destruction of Christian taboos. Accounts may include the use of a nude human altar, the inversion of prayers, desecration of Christian symbols, invocation of Demons and sexual rites.

Sensational claims concerning human sacrifice, infant sacrifice and cannibalism have repeatedly accompanied stories about Black Masses, both historically and in modern times. Such accusations should be treated with extreme caution. They belong to the same long tradition of fear, propaganda and Demonological fantasy that helped create the mythology of the Black Mass in the first place.

The Meaning of the Black Mass

The true occult power of the Black Mass does not lie simply in black candles, inverted crosses or obscene gestures. Its deeper principle is reversal. Everything considered sacred is turned upside down. Blessing becomes cursing, purity becomes pollution, reverence becomes desecration and the symbols of salvation are deliberately transformed into instruments of magical rebellion.

For this reason, the Black Mass has survived even where belief in the Devil has weakened. It functions as an act of inversion, a ritual assault upon established religious authority and, in some occult systems, an attempt to break deeply embedded spiritual and psychological taboos.

Historically, however, it remains impossible to separate the Black Mass entirely from myth. Some rites certainly occurred. Others were theatrical, political or sexual performances masquerading as diabolism. Many of the most horrific accounts were extracted under torture or invented by those already convinced that witches and heretics worshipped Satan.

The Black Mass therefore occupies a shadowy territory between ritual and accusation, magic and propaganda, history and nightmare. It is precisely this uncertainty that has allowed it to remain one of the darkest and most persistent images in the Western occult tradition.

Enter Deeper into Forbidden Magic

The Black Mass is only one doorway into a much larger and far more dangerous landscape of demonology, grimoires, ritual magic, witchcraft, spirit work and forbidden traditions. If you are tired of shallow occult entertainment and recycled internet myths, enter the Occult World Mystery School and begin studying the systems themselves. Stop circling the threshold while other people decide what you are allowed to know. There are thousands of spirits, gods, demons, magical systems, grimoires and forgotten traditions waiting beyond it, and the only thing keeping you outside is the decision not to enter.
