She is wrong because all of mankind (did) still would have fallen. Her fall might have transcended over to Adam, thus making him more susceptible to her corrupting him, subsequently, his eating of the apple.
All of nature fell because of Eve.
Considering you are on Cathinfo, I presume you to be "Resistance", SSPX, or some flavor of Sede. With this in mind, I would mention that clerics teach the way I mentioned above. A particular Risistance bishop I have heard say it more than once with my own ears. And considering he was SSPX trained and insists he has changed nothing from the way he was taught and formed, we can conclude the SSPX and resulting Resistance clerics hold this position/opinion.
Many theologians would disagree with you.
That's what I would be inclined to think as well. I have never heard a cleric suggest God would obliterate Eve, as Ladislaus suggested as a possibility, or any other conclusion of what might've happened. In general, this thread is the first time I've actually seen anyone bring up different ideas to this subject. It seems Universal to me so far that Adam would help Eve do penance/contrition and make some form of reparation, but the human race as a whole would not have fallen. That's the position I currently hold on the matter as well.
Frankly, while it is interesting to speculate on, what good does it benefit us to think of the "what ifs" on this subject? We cant change our current reality by the speculation, and we may simply be wasting time on it. Please explain to me if one thinks otherwise.
P.s. I'm not certain if yall were referring to me as "she", but just to be clear, this poster is a "he".
