Eve was first named in Gen. 3:20, is the technically correct answer.
Ah- Politesse, those of us who've known you for years know very well you are NOT a Biblical literalist. But you say you are (or grew up) a Lutheran; Wiki says
Lutheranism advocates a doctrine of justification "by grace alone through faith alone on the basis of Scripture alone", the doctrine that scripture is the final authority on all matters of faith.
I'm quite curious how you can manage to identify as a Lutheran if your interpretation of scripture is different from other Lutherans- some of whom, I have no doubt, are literalists. Okay, maybe you can say that 'faith alone' means 'your own personal interpretation of scripture'- but it seems to me that means you can't say there's any definitive creed or dogma that one must follow to be a Lutheran.
I identify as Lutheran because I grew up in a Lutheran church and came close to becoming a Lutheran pastor in my youth, it is no more complicated than that.
I do not agree that Lutherans ought to treat Luther's words as somehow doctrinally binding, and I think the majority of Lutherans would agree on that point. He was an important figure in the history of the church, but not a demigod; he could be wrong, and often was wrong, when his very healthy temper got the better of him. You know most of his writings have only had an English translation for a few decades? And I am certain that the translator of many of those would not recommend an uncritical read thereof; I know, because he was a professor emeritus at the school, and I was present for several of his sermons. As for Martin Luther, he is highly respected, but as a man; he isn't worshiped, or followed as a leader.
As for the "solas", those
have been very important to Lutherans across the centuries; people fought and died for them, and many of these were literalists to be certain. But I don't see how letting go of an ovely strict interpretation of these doctrines in the light of reason is any different from doing the same to the Scriptures themselves.
As for there being any creeds one must follow in order to be a Lutheran, the conservative branches (WELS, LCMS) would certainly insist on agreement with the Nicene Creed before allowing you to commune with them. But any ELCA branch church would not. You, Jobar, could walk in next Sunday and partake of the Eucharist without anyone blinking an eye, no conversions or grand statements of faith needed. Grace, and the dispensation of grace, are the province of
God alone by the very words and testimony you have quoted above. God alone decides whom to keep in his care, and he is no respecter of human denominations and customs. Hence why we called Luther's rebellion a Reformation, rather than the creation of a new church. There is only one church, and no human can dictate whether it comes or goes. From a Lutheran perspective, at least. Even a very conservative Lutheran, in barring you from the host, would be trying to protect you from the consequences of a sin made in ignorance, not themselves refusing you communion.
If I am mistaken in this, I would be interested to see a countering view from another Lutheran. But having studied at a Lutheran seminary for two years, I am fairly confident that the broad strokes here, at least, are in keeping with what most Lutheran clergy would tell you on the point.
I do not, personally, worship with a Lutheran congregation very often these days, having jumped ship to the UU a while back, though I will visit old friends from time to time, and I make sure that for Reformation Sunday and the Feast of All Saints, at least, I am only within Lutheran walls. No one else quite does that holiday right.

In another month's time, I will be dressed in red in the next-to-back pew alongside my mother and grandmother, belting out "A Mighty Fortress" at the top of my lungs.
Why? Because you do not have to be enslaved to something in order to love it.
I do wonder though- if you think that the Fall of Man- Adam, Eve, Apple, etc.- is only metaphorical, why do you believe we need salvation from an *actual* Christ?
Need? No one is
forcing you to accept it. But it is freely offered. What do you think it is a metaphor for? If not the divorce of humanity and divinity, I don't know what. Salvific grace heals that wound. No apples required, unless it helps you understand the nature of the problem, which is the purpose of any metaphor.
