Occult Sects: Order of Nine Angles

Order Of The Nine Angles Website

The Order of Nine Angles (ONA) is a purported secretive Satanist organization, initially formed in the United Kingdom, and which rose to public note during the 1980s and 1990s after having been mentioned in books detailing fascist Satanism. Presently, the ONA is organized around clandestine cells (which it calls "traditional nexions") and around what it calls "sinister tribes".

The ONA's writings condone and encourage human sacrifice as a means of eliminating the weak: Anton Long describes it as "a contribution to improving the human stock, removing the worthless, the weak, the diseased (in terms of character)". This "culling" serves not just a social Darwinian purpose, but is also connected to the promotion of a new Aeon: "The change that is necessary means that there must be a culling, or many cullings, which remove the worthless and those detrimental to further evolution." Thus, true Satanism, they assert, requires venturing into the realm of the forbidden and illegal, in order to make contact with the "sphere of acausal, sinister forces on the cosmos." The presencing of acausal energies, such as through culling, is meant to create a new Aeon, whose energies will then create a newer, higher civilization from the energy unleashed.
Probably because of the ONA's highly radical stance, there is open animosity between the ONA and "mainstream" Satanists such as the Church of Satan.

  The ONA publicly disavows any connection to Church of Satan, claiming the Satanic Bible to be a "watered-down philosophy". The ONA eschews the religious type of approach evident in groups such as the Temple of Set and regards other Satanic groups, such as the Church of Satan, with contempt.
The Temple of Set proscribed the ONA in the early 1980s for its avowal of human sacrifice. 

The ONA has its own, unique, ontology and theology of Satanism, based on the axioms of
(1) a bifurcation of Reality into an acausal continuum and a causal continuum, and
(2) the existence of acausal beings in this acausal continuum, one of whom is the being conventionally known as Satan.
