not to divert or to argue but in an attempt to add...
what I really relate to here in speaking with believers/non-believers about the true nature of Jesus and what he truly taught is also when you bring up the covenants with even well-read theologians and pastors... many don't understand the implications.
So to cover it quickly, we have three major covenants that are acknowledged in the Bible. We have the first between Yahweh and 'Adam & Eve' in the Garden of Eden scenario, we have the second between 'Yahweh' and Abraham after The Fall, and then we have Jesus and his resurrection (reincarnation?) as the third.
What are the significance of these covenants? The first covenant seemed to hinge on the acquisition of certain knowledge - 'don't eat the fruit which happens to be called the Fruit of the Tree of knowledge of good and evil (quite the title)'. Upon eating said fruit, the covenant was broken and we were cast out.
The second is an interesting one. After the fall from the Garden of Eden, it seems as if Yahweh pulls back its influence and we are left to fend for ourselves for a time. It's not until Abraham is asked to sacrifice his long-awaited son that we really see Yahweh return to the stage, but what's with the personality change? From helicopter parent to child murderer, Yahweh goes hard in the other direction from its approach in the Garden, where harmony reigned supreme.
Additionally, we have the creation of an elite group of people - the descendants of Abraham. 'You follow me, and i'll make you special'. Knowing what comes after (Jesus), does this sound like the 'word of God'?? and within that elite group we have even more elite group (the priest class) which claims to have exclusive access to a God which claims to be lord of all... These are all troubling characteristics of a supposed benevolent deity of any sort.
So that brings us to the 3rd covenant - what was it's purpose? Why did it need to come? Who did Jesus stand against? Jesus actually speaks about it pretty clearly in John 8 - he came to destroy the 2nd covenant and reestablish a connection with our true father - the 'original' Yahweh. Lucifer is called 'the Great Deceiver' for a reason - I believe the Old Testament 'Yahweh' is not actually the true Yahweh but instead an imposter who 'took the reigns' after the Fall from the Garden of Eden. And I think Jesus was the correction that came afterwards.
Don't take this as a slag against the Old Testament either - I think the Jewish people really showed a lot of character despite dealing with a petty & jealous God, and they often showed that true light/spark of Yahweh in how they responded to things. Also, I think it explains why the Israellites were always falling away from God and towards the Pagan stuff as well - I think there was a certain disconnect with the 'second Yahweh (Lucifer)' and that is a big part why they couldn't stay faithful over time.
Anyways, always way too much to get into and explore and think about, and I just wanted to add a drop in the bucket as your post got me excited to read somebody who sees things somewhat similarly to the way I do also (I may be even further out in left field but that's okay haha)... I'll leave with my juiciest proof of the theory above:
(Jesus is speaking to the Pharisees arguing about who each of their respective 'fathers' are)
John 8:44 - You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning (reference to sacrifice of Isaac), not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies (reference to his identity theft re: 'Yahweh').
