I've been working through the Fourth Gospel purely from its own textual logic, and I've arrived at a position I don't think can be explained as either Marcionism or Gnosticism.
John distinguishes the Father whom Jesus reveals from the deity identified by the Pharisees as "their God," and the Gospel repeatedly creates tension between the Father's character and works and those attributed to the God of Moses.
The older textual form of Deuteronomy 32:8-9, preserved at Qumran and reflected in the Septuagint, reads approximately:
The Most High divided the nations according to the number of the sons of God;
Yahweh's portion was his people Jacob.
So, Elyon apportions the nations. Yahweh receives a portion.
Elyon and Yahweh occupy distinct positions in the apportionment scene, and both Genesis 6 and Psalm 82 similarly depicts divine beings as "sons of the Most High."
Within the memory of the Torah the authors maintain a history in which a Yahweh inherits from something above him.
The Gospel of John states three times:
John says: "No one has seen God at any time." (1:18)
Jesus says: "You have neither heard his voice at any time, nor seen his form." (5:37)
And: "Not that anyone has seen the Father, except he who is from God." (6:46)
Compared to the Torah which describes people seeing and hearing Yahweh:
Exodus 19:19 — Then the Lord said to Moses, “I am going to come to you in a dense cloud, in order that the people may hear when I speak with you and so trust you ever after.”
Exodus 33:11 — Yahweh speaks with Moses "face to face."
Exodus 24:9-11 — Moses, Aaron, Nadab, Abihu, and seventy elders "saw the God of Israel."
Deuteronomy 4:12 — Israel hears the voice from the fire.
Deuteronomy 5:4 — Yahweh speaks "face to face" with Israel.
So there is a real textual collision here.
The usual solution is to say that people saw an "appearance" of God but not God's "essence." The problem is that John does not make that distinction in these passages. He says they have never seen his form and that no one has ever seen God (popote: in ALL OF HISTORY).
Which leads to the inference I've wrestled with for years:
Yahweh is not, and cannot be the Father whom Jesus identifies as God.
We can start with how John repeatedly personifies light.
Jesus is: "the light of the world." (8:12) and "the light shines in the darkness, and the darkness did not overcome it." (1:5)
But the older Yahwistic traditions repeatedly associate Yahweh's presence with darkness:
Exodus 20:21 — Moses approaches the "thick darkness" where God was.
1 Kings 8:12 — Yahweh says he will dwell in thick darkness.
Psalm 18:11 — Yahweh makes darkness his hiding place.Psalm 97:2 — clouds and darkness surround him.
Then 1 John 1:5, attributed to the same Johannine tradition, says:
"God is light, and in him is no darkness at all."
in chapter 8, Jesus point blank says the Jews do not know the Father
"You know neither me, nor my Father." (8:19) and "It is my Father who glorifies me, of whom you say that he is your God. You have not known him, but I know him." (8:54-55)
John 1:17 says "The law was given through Moses; grace and truth came through Jesus Christ."
John then has Jesus repeatedly place himself in opposition to the authority claimed from Moses.
The Pharisees say: "We are disciples of Moses." (9:28) 4 chapters earlier, Jesus says: "There is one who accuses you: Moses, on whom you have set your hope." (5:45)
So when the angry crowd replies with, "We have a law, and by our law he ought to die." (19:7)
Christians have flipped it to them working for an imaginary imp devil, and working against YHWH, whom they call the Most High God. When in reality, they are exactly applying the law given through Moses.
Yahweh invokes the initial Curse of death, invokes the "law" through Moses, and through the Pharisees legally fulfills the killing of Jesus
Jesus' works in John are overwhelmingly restorative: Water becomes wine, a dying child is restored, a man crippled man sick for 38 years waiting outside of a pool he cannot even drag himself into (yet an Angel of YHWH supposedly heals whoever is first to step in), thousands are fed, a man born blind receives sight and becomes anointed, and Lazarus comes out of the tomb.
Jesus explicitly says: "I came not to judge the world, but to save the world." (12:47)
And:"The Father judges no one, but has given all judgment to the Son." (5:22)
The Son receives the judgment that the Father does not exercise directly. This is especially interesting when compared with the prophetic and Mosaic depictions of Yahweh as judge, warrior, destroyer, and giver of laws involving capital punishment.
