> To me, the Eden story is archetypal (neither metaphorical nor literal).
An archetype is type of symbol. You are misusing the word to apply it to an entire story, especially one that you deny is metaphorical. Please define "archetypal".
> the reason the story is told in Gn. 2-3 is to show us how Adam & Eve are archetypes of the human race.
Which would make the story a metaphor.
> The text is not addressing their material formation, but the forming of all humanity: we are all mortal (formed from "dust")
Rocks are formed from "dust" yet are "immortal". Indeed, Genesis specifically states we aren't mortal, because we didn't eat the fruit of life, despite having the opportunity to do so - it does not state it has anything to do with how we are made. And the story very clearly and specifically addresses "their material formation". Indeed, that is the entire subject of Genesis 2.
> and we are all gendered halves.
We are not clones, as described in Genesis. Further, animals that are not genedered are not described in the bible at all, such as in the flood story, so presumably it's because ancient man simply didn't know about heterogametic, gonochoristic, parthenogenic, etc., organisms.
> They are not prototypes or metaphors, but representatives of all other members of the group.
Yet you claim this to be specifically untrue, in that they are "not necessarily the first hominids". Granted, your wording there is about as evasive as possible.
> Adam & Eve (and therefore all humanity)
Were they the first humans or not??
> were not dared to disobey.
Of course not. They were told to not disobey, albeit through a lie.
> They were invited to be priests and priestesses in God's temple (the earth) and to have a personal relationship with him.
Reference? They had no "personal relationship" with him. God seems to have had no clue they were speaking to the serpent, ate the fruit, etc., nor did Eve speak to God about it until commanded to do so.
> The Tree of the Knowledge of Good and Evil (though literal), was a symbol of their choice to relate to God on His own terms, or to choose to operate according to self.
Not clear what you mean here. It seems you are suggesting that having a relationship with God and "operating according to self" are mutually exclusive. I tend to agree, however, it seems you have it backwards. They chose to be more like God, yet it was with the risk of dying... and therefore not "operate according to self". They were willing to give up their selves to be closer to God.
>the choice presented by the tree is not "Are you going to be a person who thinks for himself, or an empty-headed slave of God", but rather "Are you going to act as if you made yourself and you know how best to govern yourself, or are you going to act as if
God made you and you refer to him as the one who knows you and loves you."
What??? The tree was a tree. It didn't present a choice. It does not speak, and never directly addressed. It is only referred to.
> It was not a matter of seeking knowledge forbidden to us. "The knowledge of good and evil" is a judicial idiom; humankind was being presented with a choice to judge the legitimacy of God's claim upon him as his creator and moral ground
They were not judging the legitimacy of God's claim on a moral ground, as they were described as being inherently amoral. They literally couldn't. Rather they judged God's claim as a factual claim.
> To decide against that was to cut his ties to God and stand alone as his own Master of the Universe.
Only after the fact, as an unknown outcome. God cutting ties was something imposed by God with no fore-warning.
> Eden was an invitation to life, truth, morality, and godlikeness through
Only "life". God offered the fruit of life, so that is true. However, not truth. God lied to them. Not morality. God created them amoral. Not godlikeness. The effect of eating the fruit of knowledge is specifically described as what made them like God.
the proper means to a desirable end.
Since supposedly none but life were granted in the Garden, except by way of the fruit of knowledge, the "proper means" must therefore be disobedience to God and the desirable end to be punished by God.
