I've discussed this before with A-G. That's not what she believes, unless I'm seriously mistaken. She believed Adam had feet in both those worlds, a with their existence being a much larger footprint on the spiritual side than now. Which is quite reasonable. God walked in the garden.
The Bible says God comes "down" in order to "see" so he can "know" what's going on, too. What does that prove?
As for A-G beliefs, I have no problems with them. I merely reminded her that what she was saying is not Christian any more than, say, LDS beliefs are. Mixing Christianity with Gnosticism or Cabala is not Christianity.
If you agree that anyone who claims to follow Christ, no matter what theology, be it Unitarian, LDS, JW, etc. then I suppose Gnostic beliefs are "Christian".
To be sure, all believers are to some extent "gnostic" in that they claim esoteric knowledge. Christians who believe only the "spiritual man" can know the Truth are also echoing Gnostic beliefs, because they are the cornerstone of Gnosticism Christains adopted as their own.
Specifically, in her post, AG makes the following statements that suggest Adam's created purpose was to live in the spiritual realm:
"Indeed, I perceive the creation of Adam and the Garden of Eden in the spiritual realm and thus see no contradiction at all in Genesis 1 to 3. The tree of life is in the middle of the Garden of Eden and Paradise (see below) and therefore not strictly physical."
"I perceive Adam was created in the spiritual realm before he was banished to mortality, the physical realm, and his mortal calendar/clock began. Or to put it another way, I do not perceive Adam as strictly physical."
"Adam was not made for a mere physical existence like a bacteria, daffodil, fish or cow. He doesn’t 'belong' in the physical realm and he knows it. But because he was banished to mortality, this peculiar creature made for Paradise/Eden, having immortality at his finger tips, now is grounded in the physical universe whose life forms were his to name."
Furthermore, AG proceeds to suggest that his sin resulted in "death death", i.e. the death of the soul and the body. Christian belief is centered around the immortality of the soul.
The only problem I see with AG's translation of the Hebrew is that, according to experts who actually know the language, the verse does not read muwth muwth (i.e. "death death"), but muwth tamuwth (to-die you-shall-die).
