Lucifarianism is constantly evolving.
Even the origination of the name Lucifer comes from a bastardization or misinterpretation of certain passages in Latin texts.
Many think he is the masculine representation of Venus — possibly created as a representation of the morning star that shines brightly on the horizon even with the sunrise well on its way.
Others believe he is the ruler of Hell, never really mentioned in older Goetic texts because controlling him or commanding him was not something to be attempted.
He has been called Satan, even though often that actually refers to Samael or even just a separate entity altogether. Mark Twain's short story The Mysterious Stranger, which purportedly inspired the anime classic Evangelion, never mentions the name Lucifer but the famous claymation of the story under The Adventures of Mark Twain brings the name into the fold of the many names the fallen angel is called.
It seems to me that any bad thing is blamed on him while giving credit to the exalted "forces of good" that shun and belittle him, but honestly, he doesn't seem to care.
Who or what is Lucifer?
According to most modern lore, Lucifer is a fallen angel and the leader of the hoard of Goetic demons, angels, and devils. It is widely accepted that the archetype originally stemmed from a son of the Roman Goddess of the Dawn, Aurora (in Greek called Eos and Rigvedic called Ushas, which continues the name of an earlier Indo-European deity, Hausos).
He was also pulled into Christianity as one of the many names of the devil, as seems to be the tradition with any polytheistic deity they run across. They now translate the Bible passage ridiculing a Babylonian King where his name was used (Isaiah 14:12) as "morning star" or "shining one".
As an edgy teenager who was somewhat outcast from neurotypical society, I definitely had a phase where I formed a relationship with my perception of this rebellious archetype and found an interesting idea surfaced while communing with that energy.
Lucifer was the first to disobey Yahweh or Jehovah (the Supreme Archetype or Consciousness of the Universe or Great "I Am") and be cast out of heaven. He was also not spoken about much in the actual Hebrew texts but when he was mentioned, he was represented by the Hebrew translation from the Latin word for "light bringer" or the planet Venus ("lucifer" not the proper noun/name but uncapitalized.) *
In Canaanite mythology, the same archetype is represented as Attar, who tried to take the throne of Ba'al but could not do so and ruled the underworld instead.
Or possibly the even older story of Helel trying to dethrone El ("El" meaning god and "Hell El" being the god of Hell). Hermann Gunkel reconstructed the myth to be of a hero Hêlal who's ambition to ascend above all the other stellar deities was thwarted, as the light of Venus never reaches its peak before the light of the Sun hides it away.
Most of the Hebrew religious leaders have rejected the idea of fallen angels, but the idea still sticks strong in the minds of rebellious youths and those who have devoted their lives to an edgy arrested-development.
I've always found that the best way to define Lucifer is as the Deviant Principle.
The creation of the cosmos is the product of the deviant principle.
The word "deviant" means to depart from accepted standards, usually regarding social or sexual expectations. In Lucifer's case, he tries to usurp the throne, rise above the others, or be a shining star that competes with the sun rather than being chased away by it. Always the rebel of the story or the one who acts differently than the rest.
For me, this really represents the creation of the universe, or reality in general. If everything was one giant thing (God or Universal Consciousness or Supreme Archetype) then there would be no change within it. It would exist but appear as if nothing was happening, no conflict or boundary where edges of energies meet.
This would be the same as a giant nothingness or void because if everything is the same and unchanging then it is the same (in a practical sense) as nothingness.
Time is also analogous to change.
Without changes, we would not know that time is passing, even our heartbeats and breaths help us measure the time passing. In a space where there is no change, time is both infinitely long and not in existence at all.
On an infinite timeline, the probability that any event will happen approaches infinity. So at the moment of the end of a universe where everything stops, (because of thermodynamics or the consumption of everything by a gravitational well similar to a colossal black hole) that moment will both seem like an infinity and an instantaneous moment before the chance that something will deviate from the nothingness and bring back existence reaches near infinite probability.
This rebellion from the infinite nothingness seems logically to be what Lucifer represents. As was mentioned previously, the Big Bang or morning star or light bringer is literally translated as lucifer in Latin as well, so it also connects with those stories.
The war of the angels could also be represented in this paradigm.
What defines a fallen angel or demon or angel is a hotly debated topic among the occult and religious communities. That being said, I'd like to offer an explanation for this paradigm.
The nature of angels is to obey God or the Supreme Consciousness. They bring people to heaven or the underworld, where everything is new every day and where everyone is after they return to non-existence.
Demons fight to destroy that order and maintain the disarray or conflict that is existence instead of returning to non-existence, which could represent Hell if looked at metaphorically.
Fallen angels want to dissolve the great "I Am" and be at peace, which involves the destruction of creation down to the last mote.
Angels and fallen angels are basically at war in order to bring everything into God, or kill God entirely, but the result would be the same from a practical standpoint. They both would achieve the same end of the universe and have a single, homogenous being or entity or reality that is the only thing to exist.
Their fight to destroy or to assimilate and build up is the basis for all of reality and it could be said that our existence within this universe are the battles of that war of the angels.
Lucifer draws in outcasts and those that are different purely for the sake of being different.
The devotees of Lucifer are a mixed lot of people. From theoretical physicists with a punk streak, to deviants that move beyond the accepted moral and social norms in place (like white supremacists, jingoists, or serial killers), to many people in between with other paths, all find a camaraderie with the one who is outcast because they were created to do so.
In my opinion, ethical and moral philosophy dictates that we should do what is good for the whole, but there is a paradoxical nature that makes that assumption more complex.
What if deviating from the norm creates possibilities yet unexplored to come to light or opens the path to new possibilities that are better than the current zeitgeist? Is it ethical to go against the whole if in the long run it will create a better world for the many or, as with Lucifer, create the very existence we experience?
One question that hounds Christian creation stories about original sin is that an omnipotent god which created the world and spoke, "Let there be light" also made the paradox that he would create something which was at odds with that god's very existence.
I would say that on a long enough timeline everything desires change and that only by experimentation with principles and ideas that are deviant in nature can we truly move forward into a new existence. Even if those actions may seem morally or ethically corrupt at the time or if the intent behind them is not pure.
The trodden path yields no new discoveries but being a trailblazer or lightbringer is a path that takes you deep into the shadows in order to find new light.
Be cautious what archetypes you choose to follow lest you be brought into the fold of similar nefarious entities.
*Not to be confused with noctifer or the "night bringer" of the famous poet and admirer of Sapphos, in his poem Carmina LXII (Nuptial Song by Youth And Damsels #62) which is definitely a banger.
"Hymen O Hymenæus: Hymen here, O Hymenæus!
View ye the Youths, O Maids unwed? Then rise to withstand them:
Doubtless the night-fraught Star displays his splendour Œtéän."
