Banned texts, works of Biblical criticism, and otherwise deemed heretical books are all work a look in the Bible study thread. Just know that the ultimate conclusion might not be completely satisfactory as it will ultimately be judged by not only merit, but if the Bible supports the narrative presented.
In the case of Gnosticism, it argues the Bible is completely wrong and the texts they provide are both secret information from the authors or the best guesses at what the authors would have wrote as I don’t think anyone believes that Adam, which they are arguing is a metaphorical entity anyway, wrote a book and it was preserved by people and yet the texts date to the same era as the other works of the Gnostics.
The denial of the Bible will ultimately lead to a stalemate in the texts where one cannot win over the other and the winner would be a combination of logic and trust in one or the other, and my bias will lean to the Bible being true. However, I will still attempt to the best of my ability to view the opposing viewpoint and discuss as many logical conclusions that can be drawn from the text and how it could be true. For an example of my notes so far, the concept that the book is a metaphor falls apart a bit when dealing with the characters from the Bible and then putting them in a completely different story than what is presented in the Bible, becoming a curated place for your own narrative… yet things still do not compute in such cases as the metaphorical implications of the divine mind beings that come down and save a portion of humanity from the Flood outside Noah’s ark.
This makes no literal sense in that should that be the case, why didn’t those beings save Noah and deny the evil god of the material world the leverage for an eternal servant. It also makes no metaphorical sense in that this is a form of inherited racial superiority of a hidden race as the mind beings chose to reject the descendants of the metaphorical Noah, meaning the people that the stories would promote Noah as having, which is larger than the Jewish population, including peoples all over the Middle East, Cyprus, many African lands, possibly Greece, and Russia. From there the Biblical text focuses on the Mediterranean area, but the conclusions of this is that many people could be descendants of Noah as Biblically acknowledged, and if the text is to be fully believe, all people are, then the response is that most people are disposable to the divine mind as only the chosen by divine mind grace are worthy to be kept from the evil god of the material world.
Metaphorically, this might just be an expression of how the world is typically not concerned with matters of the mind and instead worried about the physical, but it logically implies superiority of those that are one with Gnosis and the damnation of those that are not, equating them to a God that hates the world it made and the people therein. Somehow has the potential to be even worse than the most self-righteous of Christians, which is displayed in the presenter concluding not only are Christians wrong, but the founders worship death and suffering and promote it against the wishes of Christ, and those today that follow it are like them in service to this version of God proclaimed to be true.
In my breakdown I will go over as many implications I can possibly over the resulting theology that comes from a God that is actually Satan and how that would have effected a literal history, a Biblical narrative, the world today, and metaphorical considerations to cover my bases. Unfortunately I am a bit pressed for time with other commitments, but I will still work on this and finish it despite the length of time that elapses.
