Everything asked and stated here in the post and in the responces can be easily looked up and researched. Nothing is super secret.
Between the death of Christ and the formation of a United Church by Rome, some 200 to 300 years after Christ, there were many many widely different beliefs and perspectives about Jesus and his teachings. Dogma, belief, and practices ran a spectrum all over the place. For example, I heard recently that one of the early sects believed Jesus had become a 100 foot angel.
Just think about the crowds that learned from Christ, each gleaning one thing or another from a gathering. And then, inspired by His Words, they taught from His teachings and the miracles they witnessed, and humans being humans, filled in the gaps of all things they did not know with each new generation of that sect. And multiple sects did this.
The Gnostic texts came from this diversity of material. It may be completely false or completely true or some mix in between. But as Conservative Christians we don’t embrace any of these other texta as truth because they are considered fringe and go against a united view of Dogma, Belief, and Practice. The more we embrace the alternative view the further we move away from what is safetly and widely accepted as true, whether that is wrong or right.
The Dead Sea Scrolls were a bunch of scrolls- books and letters- that were found in a cave or tomb that predated many of the ones held by the church up until that point. Including the ones that make up the Bible.
Because they are older, the dead sea scrolls reveal edits and add ons to the original texts of the Bible that occured over time. The older versions found amongst the dead sea scrolls have largely become accepted as closer to the original text. Because of this, many modern Bibles translate the text according to the dead sea scroll versions with notes indicating what the Bible said after it was altered.
Some Churchea cling to the King James Bible, which remains altered from the older texts, holding the King James version as truer. This may be because of the belief in the unerring nature of God’s Word, confusing God’s Gift to men, which is unerring, with man’s handling of that gift, which is erring and self serving As man also sacrificed the Son. And the Bible itself hints that weeds were sown with the wheat, and as the Prophet Jeremiah says to his own people, the scribes have lied.
There comes a point where we must examine and decide for ourselves what is Truth and whst is not. And my personal compass as I have said many times before is Christ’s statement on the two Highest Commands. LOVE is the compass when any questions arise. How we should behave, the direction we should move, the goal we should strive for. Whether angels are servants of God, other dimensional beings, or aliens. Whether Gnostic texts or Mainstream belief is correct or far from it. No matter what may be the physical or spiritual reality of any of it, if LOVE does not show the way then it is not a way worth going.
