This is from the discussion here (Marcion’s non-Jewish Jesus):
Prof. Neil Godfrey:
We do not know the details of what Marcion’s gospel contained. Tertullian tells us that he writes from memory (his first draft was lost or stolen), and Marcion’s gospel was said to have been regularly being revised even after Marcion’s time. So by the time we are reading accounts of Irenaeus and Tertullian we cannot know what version of Marcion’s gospel they were reading. Nor can we know how much they were paraphrasing accurately from memory.
But there is good reason to think that Marcion’s gospel was closer to the gospel of Luke’s than it was to the other canonical gospels — discussed in Did Marcion Mutilate the Gospel of Luke.
There must have been some overlap between Marcion's gospel and canonical Luke for Marcion's opponents after Justin to have thought it was canonical Luke he had mutilated. Most notably Luke is the only gospel containing that passage so central to Marcionism — the statement in Luke 6 about the 2 trees and fruit of good and evil.
Marcion's Alien (Top) God did not create the physical world, but left this to his subordinate Demiurge, the god of the Jewish bible. It is correct that the idea does not originate with Marcion — Marcion embraced it from well known philosophical speculations.
How are your Old Testament polytheism chops? Are you familiar with the notion that the God in the Old Testament is actually a conflation between Yahweh and the gods of the Canaanite pantheon?
This hypothesis asserts that the original god of Israel was a bull-god called El, and that Yahweh was considered a separate deity. – But that over time these two gods were combined to create one monotheistic god. It involves a divine family, and all kinds of gods and ‘Sons of God’.
I can’t help but wonder if Marcion’s theology is based on that knowledge, or at least based on some naïve screwed up misconstruction related to it. He wouldn’t have to invent a new god with a new son, he would only have to read the OT with a different slant.
Well this makes sense too… maybe Marcion simply read the LXX version of Deuteronomy 32:8-9 (and similar other places):
32:8 When the Most High gave to the nations their inheritance, When he separated the children of men, He set the bounds of the peoples according to the number of the sons of god.
32:9 For Jehovah's portion is his people; Jacob is the lot of his inheritance
[The god] Jehovah received the tribe of the Jews from the Most High god. Jehovah gave the Jews their law and prophets and will give them their messiah, but the Most High god was a totally different god – and Jesus is the son of this Most High god, not the son of Jehovah.
Notice that this verse is corrected to remove the inherent polytheism and to reflect monotheism in current Bibles.
Just figure out who Melchizadek (sp?) was worshiping and you got it!
The one in Genesis 14 was a high priest of El [Elyon – i.e. the god most high]. He [Melchizedek] never heard of Yahweh. Genesis 14 is an old Canaanite story. The ‘Yahweh’ in verse 22 is a insertion. The entire chapter (14) is an insertion.
Melchizedek was the King of Salem – named after S[h]alim the god of dusk. Shalim was Shahar’s brother. They were both sons of El but Shahar was mothered by As[h]arah and Shalim was mothered by Anat.
Now, just for fun, whose god do Christians actually worship?
The Jewish God or Marcion's?
Marcion called the god of Jesus, god the father, the good god – the god of goodness. 1 John 8:4 (i.e. “god is love”) is closer to Marcionism than Judaism. There's nothing in Jewish scripture that says that YHWH is love. If anything, he's the god of justice — see Isaiah 30:18 — exactly what Marcion said he was.
Of course, I think that Marcionism was assimilated (along with Judaism) by the later Catholics so that we get the contradictory modern Christian god. A god who is both love and justice. Both all forgiving and jealous. One is Marcion’s god, the other is the Jewish god.
