I wouldn't say the old beliefs crumbled, but that they have been expanded on significantly. The old beliefs represent probably around 10% of what is on ToZ now with all of the new knowledge revealed. Our stance and position towards the Gods did not change, but it has been tremendously improved and expanded.
As far as Satanism go, except of JoS at the time, all types of Satanism were nothing more than creating an ideology by turning the basic christian doctrines upside down, and this is how humanity will always remember it. This is exactly what christianity did at the beginnings as well, they took the ancient religions and turned them upside down by preaching that the Gods are "demons" and evil beings and that spirituality is from those evil beings to turn people against "God", and to burn and torture to death people who were caught or reported practicing spirituality and meditation.
The solution is not take christianity and its ugliness and turn it upside down into something just as ugly, but to go far deeper into the past and show that humanity venerated the same Gods in all religions. "Satanism" is a modern construct that appeared a few decades ago by the anti-christian rebellion of Anton LaVey, Zevism as can be seen now on the website is the reconstruction of ancient knowledge about the Gods and meditation, with the direct oversight of the ancient Gods. Most meditations on ToZ are ancient (especially the Sacred rituals in Hall of Osiris which Priest Alexandros is expanding about publicly), the knowledge about the Gods is ancient, there is just no comparison.
ToZ is on a whole another reality compared to all other Satanism "religions" combined because the Gods are here and see what is happening.
We have to be really objective here. Satanism was a popular reaction to the stranglehold of Yehuboric Abrahamism. It was theatricals. LaVey was doing clown theatricals to agitate Christians. Their "spiritual knowledge" was lesser Western type occultism, at best and if it even existed. As for answers on any serious topics, there were none. Just reaction based reflections.
Of all of the "Left Hand Path", only the JoS had actually any meaning at all. The rest of it is just circus with the dark forces as decided by the Hebrews and Judaism (it's their own creation, in reversed form. In many cases, these people just follow Judaism and destroy themselves by the cultural insanity of Christians, Islamics and Judaists). No value given to them, just a fake, Matrix programmed reaction. The prerequisites for this reaction are embed in already the slave program, same as the "parameters".
JoS in that case went a step further in this and discovered 3 core factual truths about this:
1. That Abrahamists reverted the Old Gods (who existed before the enemy)
2. That Spirituality aka Meditation and evolution is necessary (another nail in the coffin)
3. That these values that are perceived as "reactionary" have their own validity and extend past the "reactionary Satanic" spectrum.
4. That the Gods should be restored out of this.
5. That what was known by the enemy as "Satanism" actually has eternal roots and is an inversion of what was before.
6. That there are ethical undertones to these topics, a gap left empty because they weren ever defined on no basis in JoS but were "understood by all" regardless.
This was the core premise of the JoS.
However, this restoration could never happen in the limited matrix of the enemy as it were under any form; because you were still in their programming language. The JoS was self-defeating it's own premises. The above were the problems. JoS time was a management of these problems, a resistence, but not a solution to them. In fact, it fed the same arguments it was working against.
This moves us to the second layer of questions.
1. If these are the Old Gods, why one obsesses still with the Goetia?
2. If Spirituality and Meditation are the point, why one is restrained to lesser forms and one should not access higher forms?
3. If the values outside the spectrum of reaction have major value, why not go to the source and sit down to debate the "Satanic Forms" and all of that nonsense, if you know it's just products of that reaction?
4. If the Gods are to be restored and all of the above and this takes out all the enemy context, isn't this their restoration? It is.
5. If the original core religion which encompasses all of mankind and is proven to be such, exists, why should someone stay on the inversion sphere and all the insanity of this?
6. Why are any politics needed, especially if they are totally detrimental to the Gods and the people following them, and dead fossils, if the Ancients actually positioned better and eternally on the subjects and all their knowledge surpasses all these temporal "reactions" and cultural mini emo boy revisions?
Therefore, we want to be free and restored to the full versions.
The answer to this is ToZ.
There was no way to want these things and discover these things, and for this to not happen. It was destined to happen from day one when the Truth was restored. Now, we live testament in seeing this.
