Temple of Set / Setianism

The theistic Left-Hand-Path organization founded by Michael Aquino in 1975, centered on Set, Xeper, and the deliberate becoming of the individual psyche.

“Setianism” can sound, from the outside, like a variant name for Satanism. Inside the current, the distinction is the whole point. LaVeyan Satanism treats Satan as a symbol of carnality, self-interest, and revolt against herd morality; the Temple of Set teaches that Set is an objective, non-natural intelligence and the patron of isolate selfhood. The difference isn’t decorative. It changes the practice from symbolic atheism into initiatory theology.

A tradition of becoming

The Temple of Set is a Lineage because it transmits a doctrine, an order structure, a body of texts, and a way of reading the Left-Hand Path. Its central word is Xeper, a Setian rendering of an Egyptian verb usually glossed as “to become” or “to come into being.” Practitioners use it to name more than personal growth. Xeper is the willed emergence of the self as a distinct, conscious, and increasingly self-created being.

That makes Setianism one of the clearest modern statements of the Left-Hand-Path ideal: not union with a god, not surrender to cosmic law, but the preservation and development of individual consciousness. Set is the figure of that separateness. In the Temple’s own language, he is the principle that stands outside the ordered natural world and gives the individual the power to question it.

Origin and historical development

The Temple was founded in 1975 by Michael A. Aquino, then a senior member of Anton LaVey’s Church of Satan and an officer in the United States Army. Aquino had joined the Church of Satan in the late 1960s and rose quickly through its hierarchy. By the mid-1970s, he and other members objected to LaVey’s sale of Church degrees and to what they saw as the reduction of initiation to a public persona and a fee structure.

Aquino’s own account makes the schism theological as well as organizational. In June 1975 he performed a working he described as an invocation of Satan and received a text he called The Book of Coming Forth by Night. In that text, the figure behind Satan was identified with the Egyptian Set: not the Christian devil, but the older adversarial and isolate principle. Aquino and the members who followed him broke with LaVey and founded the Temple of Set.

The new order therefore began by refusing the Church of Satan’s central interpretive move. For LaVey, Satan was a symbol, useful because it dramatized material appetite, individualism, and refusal of religious guilt. For Aquino, the symbol pointed to a real metaphysical presence. Setianism kept the Left-Hand-Path stress on individual sovereignty, but made it explicitly theistic.

Main figures and the order

Aquino is the founder and principal systematizer. His background mattered to the order’s style: he was a military officer, a trained political scientist, and a writer with a taste for formal structure. The Temple’s documents read less like countercultural provocation than like an initiatory manual with footnotes.

The order is organized by degrees and by local working groups called pylons. Degree systems are common in ceremonial and initiatory traditions, but the Temple uses them to mark growth in self-knowledge rather than obedience to an external authority. Pylons give members a local or affinity-based setting for study, ritual, and specialized work. The order also developed specialized groups and internal schools for particular areas of practice and research.

Stephen E. Flowers, who has written under the name Edred Thorsson, is the best-known practitioner-scholar associated with the current. His Lords of the Left-Hand Path places Setianism inside a longer history of antinomian and self-deifying traditions, from Tantric left-hand practice through Western esotericism.

Major works and institutions

Core teachings

Setianism turns on a few linked ideas.

Set as objective principle. Setians do not treat Set merely as a mask for the self. They hold him to be an objective, intelligent principle: the source or patron of isolate consciousness, the force that allows the individual to stand apart from nature, tribe, and inherited law.

Xeper as becoming. Xeper is the doctrine most associated with the Temple. It names the process by which the individual psyche becomes more fully itself through conscious choice, discipline, initiation, and self-recognition. It isn’t a one-time conversion. It’s a continuing work.

The Black Flame. The current often speaks of the Black Flame as the inner gift of isolate consciousness. The image marks the part of the self that doesn’t simply flow with nature, instinct, or collective expectation. It is the capacity to know, question, choose, and become.

Apotheosis of the individual. Setianism shares with other Left-Hand-Path currents the goal of self-deification. The aim is not worship of Set as a lord before whom the practitioner dissolves, but alliance with Set toward the development of the practitioner’s own divine-like selfhood.

Practices, systems, and beliefs transmitted

Setian practice is usually described as initiatory rather than devotional in the ordinary sense. Members read, write, perform ritual, and test their own claims through disciplined self-observation. The ritual work may draw on Egyptian symbolism, ceremonial magic, dream work, or specific pylon curricula, but the recurring question is the same: does this act sharpen the practitioner’s capacity for Xeper?

The Temple also transmitted a distinct way of reading the wider occult inheritance. It accepted much of the will-centered ritual grammar associated with Aleister Crowley, but rejected Thelema’s language of cosmic law when that language sounded like submission to a larger order. It stands near Luciferianism, because both currents read the adversarial figure as a bringer of consciousness, and near Chaos Magick, because both prize the practitioner’s agency. But Setianism is less improvisational than chaos magick and more theologically fixed than most Luciferian writing.

Some Setian and adjacent Left-Hand-Path groups also work with Nightside or Qliphothic maps. In that frame, descent into shadowed or adverse symbolic regions isn’t treated as corruption for its own sake. It is a controlled encounter with what ordinary spiritual paths avoid, used to strengthen the practitioner’s selfhood.

Influence on modern spirituality and metaphysical practice

The Temple’s membership has always been small, but its conceptual influence is larger than its numbers. It gave the modern Western Left-Hand Path a precise theological vocabulary: Xeper, isolate intelligence, the Black Flame, and the idea of Set as the adversarial principle behind self-created consciousness. Those terms now travel through Setian, Luciferian, Satanic, and wider occult writing, sometimes detached from the Temple’s own discipline.

Its sharper contribution is the distinction it forced inside Satanism itself. After the Temple, readers could no longer treat organized Satanism as one thing. There was LaVey’s atheistic-symbolic current, the Temple’s theistic-Setian current, later activist non-theistic currents, and independent traditional or theistic Satanisms. That taxonomy still structures how practitioners explain the field to outsiders and to each other.

Controversies and legacy

The Temple’s first controversy is its origin story. LaVeyan Satanists tend to read the 1975 schism as organizational dissent dressed up as revelation. Setians tend to read it as the moment when a symbolic movement reached the limit of what symbolism could carry. That dispute still matters because it asks what an adversarial religion is: a dramatic philosophy of the self, or a relationship with a real non-natural intelligence.

The second tension is hierarchy. The Temple’s degree system, pylons, and internal documents give the current intellectual seriousness and continuity. They also sit uneasily beside a doctrine of radical individual sovereignty. Setianism answers that tension by treating structure as an initiatory instrument, not a demand for submission. Whether that answer satisfies a practitioner depends on what they want from the path.

The public legacy is also shaped by confusion. Outsiders routinely flatten Setianism into devil worship, moral panic, or occult extremism, and each of those readings misses the same thing. The Temple is a small, literate, self-consciously initiatory body whose central claim is about becoming, not mayhem. Its lasting place in the field is as the clearest theistic statement of the Left-Hand Path in the modern West: a tradition where the question isn’t “what god do you obey?” but “what are you becoming?”
