Yes sir I have, though I have not thought about Satan even close to the degree that Heisner has. I only know what I have been shown and not more. That said I will give you the hypothesis, not conclusions, that I have. I think the serpent is Satan. Perhaps his original and intended role was to track the misdeeds of humanity and report to God. I can see how doing that for a few tens of thousands of years would give one a low view of humanity. And then to hear that God was going to make them in His own image? Its’ pride would not let it serve these creatures whose venal misdeeds had been his area of study.
The plan to uplift humanity started with this Adam kid, whom the LORD God was building all kinds of hedges around. Maybe he was like a prosecutor who crossed the line and went from catching and reporting misdeeds to entrapment. Nevertheless, God’s wisdom will prevail and it has all worked to His glory in Christ.
I believe Job 1:6 and 2:1 describes Satan being among the “sons of God” who present themselves, unless you are reading the Septuagint in which case it says “angels” (while retaining “sons of God” in Genesis 6). I believe I had that on the board on the 2nd half of the video.
Regarding the book of Enoch I feel more certain. It is not canon and there is a reason that it is not canon. If you will research the origins of the book you will learn that there was an original first chapter, which seems to be what is referenced in Jude. Its origins were in the distant past- though that does it make it from the original Enoch. That first chapter is orthodox and I believe was an inspired prophecy (hence Jude using it).
But the rest of the “book of Enoch” was added in stages later. There is a sharp break between chapter one and the succeeding chapters. The subject changes completely. I don’t give the rest of it any weight at all. I don’t consider them inspired writings- nor did those whose job it was to identify the canon. So I know it is “fun” reading, and titillating, but none of that makes it true.
I think Heisner goes off the rails when he views early Genesis through the lens of the book of Enoch. The only way early Genesis makes any sense is to view it through the lens of Christ. When we do, it is astounding how much more sense it makes. The ancient Jews did not have that advantage, we do. We should use it!
