Working with angels & Demons
Ceremonial magic (ritual magic, high magic or learned magic) encompasses a wide variety of rituals of magic. The works included are characterized by ceremony and numerous requisite accessories to aid the practitioner. It can be seen as an extension of ritual magic, and in most cases synonymous with it. Popularized by the Hermetic Order of the Golden Dawn, it draws on such schools of philosophical and occult thought as Hermetic Qabalah, Enochian magic, Thelema, and the magic of various grimoires. Ceremonial magic is part of Hermeticism and Western esotericism.
Demonolatry--not to be confused with Demonology (the study of Demons)--means, literally, the worship of Demons. Although the word is old, it was originally used (like the label Satanism) as a term of derision to refer to a variety of different religions that the early Church persecuted. It was not adopted as a term of self-reference until relatively recently (late 1950's/early 1960's). Even then, Demonolatry was clandestine. It was not until 1998 when the Guild of Demonolatry (now defunct) finally funded a website--Tezrian's Vault--devoted to the religion that Demonolatry came out-of-the-closet. That site closed in 2001. Previously, many sects simply referred to themselves as followers of [insert name of Demon here].
Modern Demonolatry is a polytheistic or pantheistic religion (depending if you see some Demons above others or all of them equal) in which Demonic entities are worshiped and worked with as wise divinities. Each Demon is the wellspring of a single energy source. These energies can be defined as universal elements, emotions, or ideas. The most common pantheon of Gods used are Demonic--from Christian mythologies about diabolical beings, which were formerly the Gods of pre-Christian pagan religions. However, Roman, Greek, Egyptian, and other pantheons have been used. - From The Complete Book of Demonolatry by S. Connolly
For Luciferians, enlightenment is the ultimate goal. The basic Luciferian principles highlight truth and freedom of will, worshipping the inner self and one's ultimate potential, and to encourage and celebrate the same within all. Traditional dogma is shunned as a basis for morality on the grounds that humans should not need deities or fear of eternal punishment to distinguish right from wrong and to do good. All ideas should be tested before being accepted, and even then, one should remain skeptical because knowledge and understanding are fluid. Regardless of whether Lucifer is conceived of as a deity or as a mere archetype, his presentation within Luciferianism is a representation of ultimate knowledge and exploration as well as humanity's savior and a champion for continuing personal growth. - Wikipedia
Satanism is a group of ideological and philosophical beliefs based on Satan. Although several historical precedents exist, the contemporary religious practice of Satanism began with the founding of the atheistic Church of Satan by Anton LaVey in the United States in 1966. Prior to that time, Satanism existed primarily as the subject of accusations by various Christian groups toward perceived ideological opponents rather than a self-identity or expressed religious belief. Satanism, and the concept of Satan, has also been used by artists and entertainers for symbolic expression. - Wikipedia
Hermeticism is a set of philosophical and religious beliefs based primarily upon the writings attributed to Hermes Trismegistus, a syncretic amalgamation of Hermes and Thoth. The movement is generally traced to Alexandria in the first centuries of the Common Era, where it unified elements of Jewish and Christian mysticism with Hellenistic philosophy and Egyptian occultic beliefs. The resulting composite tradition proved to be both persuasive and perdurable, as it proved compelling to both Muslim scholars in the early Middle Ages and European intellectuals at the dawn of the Renaissance. In particular, the notion that the universe operated based on orderly principles — in this case, represented as cosmic vibrations in the substance of the All — was instrumental not only to western occultism, but also to the development of the modern scientific method. This connection can be seen most clearly in the hermetical and alchemical treatises written by some of the most influential thinkers of their respective eras, including Giordano Bruno, John Dee, Francis Bacon, and Isaac Newton. - from New World Encyclopedia
