Infused Knowledge and Impeccability are quite impossible for Adam and Eve.
This is what I love about discussion forums. You really get a chance to poke and prod at definitions and come to a better understanding of them!
OK – how do we define ‘impeccability’? Is it an
a priori or
a posteriori assertion? In other words, do we look back on Mary’s life on earth (now completed) and say, “she
did not sin, and therefore, she is impeccable”? Or, do we say “it is a truth, able to be known at the Annunciation (or maybe, even at the Immaculate Conception) that Mary is impeccable”?
Having asked that question, here’s another: by ‘impeccable’, do we mean “incapable of sin” (in the past, present, and future), or just “has not sinned”?
They did not possess the “Knowledge of Good and Evil”.
I see where you’re trying to go. However, I think I disagree with you. The point of the allegory of the “Tree of the Knowledge of Good and Evil” isn’t that they didn’t have this knowledge – it’s that God is prohibiting them from appropriating it for themselves. They already
knew what was good and what was evil – God told them! (That is, when He said “do this but not that”, God was giving them the knowledge of good and evil inasmuch as was applicable to them.)
They would not have this knowledge until they partook of said tree.
Not necessarily.
They were alive, weren’t they? And God prohibited them from eating from the Tree of Life, too, right?
(And, lest you say "yeah, but they weren’t
immortal, keep in mind that the Church actually
does say that, among the preternatural gifts they received, immortality was one of them.

)
Since if there was a Tree of Knowledge of Good and Evil, and Genesis is the de facto first book of our Religion, then where did Evil Originate?
With the first sin of a created being.
If this tree was created before the Great Rebellion of Angels, then there is obviously a quandary.
No, not so much. I think you’re placing too much stock in this ‘tree’…
