The "Gospel of Thomas" is a non-Canonical (Gnostic) "gospel". It is with good reason it is not included in the Bible.
As for the last part of what you wrote, you have seriously deviated from the Biblical Christian faith. The serpent was a deceiver. You are bordering on some form of Luciferianism to even suggest that the serpent is the one that was correct, and that God was wrong to forbid Adam and Eve to eat from the tree of the knowledge of good and evil.
I think you may also need to re-read the rules of this forum.
This IS the Orthodox teaching. What part of unorthodox are you not getting? Only the Orthodox can be Christian? I do not believe the catholic tenet, I believe on the side that didn't accept the catholic tenet of the 1-3 centuries. I've studied them. I see both sides. I choose the side that didn't use deception to build a "church".
I read and know the forum rules. To refer to my thoughts as Luciferianism is basically saying I am anti-Christ. Clean your own mind. I use scriptures from the Gospel and Paul to refute. I haven't even brought much in from the non Canon books, usually I show the a Canon scripture and a non Canon one to prove that they align.
You follow the OT. And Christ told the Jews that they were lied to. That they followed a deceiver. And those very books (of thought) were essential in killing Jesus. The Jews were ignorant (of truth) yet you believe that they are the word of God. They were a battle of angels, before truth.
Was God in the Burning Bush? Better tell Stephen. He backs up what I say about angels.
Acts:
30 And when forty years were expired, there appeared to him in the wilderness of mount Sina
an angel of the Lord in a flame of fire in a bush.
31 When Moses saw it, he wondered at the sight: and as he drew near to behold it, the voice of the Lord came unto him,
32 Saying, I am the God of thy fathers, the God of Abraham, and the God of Isaac, and the God of Jacob. Then Moses trembled, and durst not behold.
33 Then said the Lord to him, Put off thy shoes from thy feet: for the place where thou standest is holy ground.
34 I have seen, I have seen the affliction of my people which is in Egypt, and I have heard their groaning, and am come down to deliver them. And now come, I will send thee into Egypt.
35 This Moses whom they refused, saying, Who made thee a ruler and a judge?
the same did God send to be a ruler and a deliverer by the hand of the angel which appeared to him in the bush.
There is only Christ, who taught us the way. There is nothing in the OT that shows the way, or the Jews would have known it. They wanted a worldly warrior.
I wish you would use Gospel scriptures (as I do) to make your point. Use the OT if you like. But most of all open your mind to see all things before just following a gang who created creeds. Creeds aren't scriptural. They are beliefs of understanding. Based on what a few want the many to see.
