So can you explain how not having one thing or other makes one faulty, or blemished.
As I said, ignorance of relevant things is a blemish. You don't want to put your money in a bank if the manager has no concept of right and wrong, for instance.
Eve ate the fruit at a time when she couldn't tell right from wrong. Since God imposed that ignorance on her, no one can accuse her of choosing to do wrong, deciding to sin, since she had no idea what wrong or sin were. This changed when she ate the fruit of course, but the same was still true of Adam when he ate the fruit ─ he too was incapable of wrong, of sin.
And sin, the fall of man, death entering the world, are nowhere in the text. No, God is quite frank about why he kicked them out ─
Genesis 3:22 Then the LORD God said, "Behold, the man has become like one of us, knowing good and evil; and now, lest he put forth his hand and take also of the tree of life, and eat, and live for ever" ─ 23 therefore the LORD God sent him forth from the garden of Eden, to till the ground from which he was taken.
For example, say Adam and Eve are perfect. Would Eve not having testicles make her imperfect?
If we consider Eve to be, as the story says, the first female H sap sap, then her having testicles and lacking ovaries would be a major design fault / blemish / imperfection, yes.
Does Adam and Eve not being like God,make them imperfect?
The God of the Garden story is a long long way from perfect ─ his untrue claim that if you ate from the tree you'd die the same day (2:17), and changing his story about the tree from Don't eat from it, it'll kill you (2:17), to Don't eat from it because I said so (3:11), and from his petty, vindictive, Trumplike punishment of Eve, that thereafter human birth should be painful (3:16), and of course his ignoble motive for kicking them out (above, 3:22-23).
Adam and Eve were not to eat of the tree of knowledge of good and bad, because they were not created with the right to decide for themselves what is good and bad.
That last bit isn't in the story ─ in particular they were never told, Don't make your own choices ─ but if it were, it would underline their innocence of the charge.
Rather than submit to this, Adam and Eve rebelled against that authority.
Nope. Each was incapable of that when each ate the fruit.
What blemish is their fault? They both knew it was wrong to take fruit from the one tree.
If there's one thing the story is perfectly clear about, it's that they did NOT and could NOT know it was wrong to eat the fruit.
On the contrary, the account of Adam and Eve sinning against God, is supported by scriptures running fro Genesis through to Revelation.
I'm not defending the NT. I'm defending the Garden story against the NT. It does NOT say what Christians keep wanting it to say. Paul can't change that. Augustine of Hippo can't change that. Nor you nor I can change that. It is simply so.
