And so you're suggesting that Adam was thrown out of Eden because he did exactly what the "us" did?
Read the text yourself. God states his reasons for expelling Adam and friend from the Garden ─ lest Adam get to live forever. At no point does God offer any other reason.
Or possessed something they had?
The text has God say he fears they'll get to live forever and become like him, so he expels them. That is, he possesses something that they do not possess.
The need for a redeemer was mentioned 7 verses before that, Genesis 3:15.
With respect, I don't see that verse calling for a redeemer. And if it does, then it calls for a redeemer for the snake, not for anyone else ─ an interesting theology, that.
To sin means to miss, as in this case, the mark set by God. Adam did this.
The text gives you no support for that. (Nor should it ─ the ideas you mention are from many centuries later.) It makes no mention of missing, sinning, &c. Instead it has God state clearly that he's expelling them because he doesn't want them to live forever and become like him.
Man fell in as the account reveals, death of man began then.
You simply aren't reading what the text says. I repeat, the text makes no mention of sin, original sin, the Fall, death entering the world, 'spiritual death' or anything of the kind. If you disagree, quote me the words that say those things.
And reconcile them with Ezekiel 18:20 and the rest of Ezekiel 18, where it's clear stated that each is responsible for his or her own sin, and is NOT responsible for the sin (if any) of his ancestors.
It's all there, does it have to be spelled out to you?
It's all there. I've already spelt it out for you.
In that case don't complain to me. Take it up with Zeke.
How could you give a verse on sin and say it isn't about sin. That it was only invented later? Who doesn't die?
Dear oh dear. Okay, I'll spell this out for you too.
The Garden story never mentions sin, original sin, the Fall of man. You know that because you've reread the text with a clear mind, laying aside what other people have told you it should say.
The idea of original sin is much later theology. That doctrine is expressly contradicted by the whole of chapter 18 of Ezekiel, which I trust you've now read in full. I cited one verse which (like the rest of it) makes it perfectly clear that sin is
not inherited. Therefore the Tanakh expressly rejects the notion of original sin.
Got it?
