“In other words, introducing a single, unnamed woman here is causing more skepticism directed at egalitarianism, not less. Particularly when one interprets “she” as being “Eve representing all womankind,” in which case the use of the present tense is no longer so problematic.”

You lost me a little here. You are saying that some or many scholars cannot agree that “A” woman means a singular woman. Yes, I’m aware of that, yet I have trouble really thinking otherwise because of the deliberate switch from plural to singular. But, I yield some on that by including, “or a group of women”. The deliberate switch just seems so glaring to me.

As for Eve representing all womankind, I don’t think that makes sense because then when Paul says “nevertheless SHE will be saved”, it cannot be referring to Eve representing all womankind. Eve’s destiny had already been determined long ago. It seems it has to refer to A single woman and the “they” to her husband, or to a group of women. But I prefer the single woman myself.
