1) Eve is not an afterthought in the endowment. The actual phrasing is, "Is man meant to be alone?" - and the answer is a resounding, "No." The message is that man needs a "helpmeet" - and "helpmeet" means, at the most basic level, "partner; one who walks beside another". We tend to translate it as "helper" - someone who follows directions, but that's not what the word means. That is the actual foundation of the rest of the story - that Eve, based on the actual word used, is a partner, not a helper, and that man is hopeless without her. That's not a knock on man; it simply says that the ideal is not an individual, but a couple.
2) When God asks what happened, Adam did not "pass the buck" - and his answer was not weak in any way. It was straightforward and honest. If I change the wording a little but keep the exact same meaning, he said:
You commanded me to stay with my wife. You said it is more important to stay with her than to continue alone without her, even if I was alone with you. She gave me the fruit, and, knowing I needed to stay with her - that I simply can not be perfect (complete, whole, fully developed) without her, I ate it.
That means Adam realized that being with Eve away from God was better than losing her and staying with God. In a very real way, that means, in the moment, Eve was more important than God - since his faith in God told him they would get back to God together, if he stayed with her, but they couldn't do and be what they were commanded to do and be without each other.
Eve was the most important thing in Adam's life, and he proved it by leaving God to stay with her.
3) When God asked Eve what happened, she also did not pass the buck - and her answer was not weak in any way. It was straightforward and honest. If I change the wording a little but keep the exact same meaning, she says:
I got tricked, and I ate the fruit.
That is exactly what happened. She was "beguiled" (tricked, deceived), and she ate the fruit. Her answer not only was honest, but it also didn't duck responsibility. She said, "It was my fault. I got tricked." She displayed a lot of strength in that answer, taking responsibility for what had happened.
Nothing in what I just wrote is a stretch in any way. It is based only on the actual wording. It shows a committed couple who each took responsibility for what they had done and, above all else, were committed to each other.
Yes, again, there are issues that I hope change, but we don't need to make more issues than there are, regardless of what others have said about it. We can interpret the presentation in a way that minimizes or eliminates, legitimately, some of the issues - and that can allow us to deal better with the other issues and hope that they change. It's the difference between some rain and an avalanche.
