I've recently studied the 1 Timothy 2:11-15 passage and am looking at this perhaps very differently than what I've seen others may be focusing on, given the context in the chapter. I'll be brief...
I think the verse that is the key verses for the chapter is 2:2,3 - the rest is all about helping that cause. Actually, the Apostle is adamant about not violating that cause ("I urge", "I want", "I do not permit"). He is not mad at men or women here, he is jealously safeguarding both and the church as a whole. Let me explain.
These admonitions above are the Apostle's commitments to hold together a new liberating faith so that it could continue to speak that faith in Christ to a hostile culture. His sense of how Christian liberated women could again (just like Eve began Adam's and our destruction) undo God's purposes for the Church was so acute that he issued stern exhortations. One to men about not arguing and being holy, and to women about propriety. Propriety is defined in Webster's as "behavior that is accepted as socially or morally correct or proper". When he says "women will be saved through childbearing", I believe he meant that they would be physically saved from harm, as the culture would more readily accept them. In that culture, unbridled liberality would have been not only unacceptable, but also physically dangerous to the women - and to the message to the community by the Church as a whole. Just as the Apostle did not crusade against slavery, likely for the same reasons (leading to the demise of his mission), he also wasn't about to lead a women's rights campaign at that point of their culture for both Jews, Greeks and Romans.
So, the passage in Genesis is not used to show that man is above woman, but that just about how the same destruction caused by Eve's being deceived could also destroy the Church. There is room to grow this thought, but I think that is enough for now.
Also, this passage isn't about roles or being saved through childbearing or being saved by the Christ-child, but about saving the mission of the church during that specific time.
The implications of this for now? The Church and each one of us must put the Mission first, the Great Commission. Propriety means living in such a way, by the Spirit of Christ, that our lives individually and in community speak of peace, quiet, godliness and holiness. Let the world hate us for the same message it also hated Jesus - but not from either extreme legalism (arguments about all those gray areas/doctrines) or liberalism (I don't know how we could be more liberal than our present day culture, so we may be safe here :) )
Another implication of these thoughts is that this passage, interpreted in this way, is not a proof-text on roles at all. The whole direction of the chapter is not at all about that issue. In fact, what may be viewed by women who read this passage as objectionable and from a woman-hater, instead should be viewed as the Apostle trying to preserve the lives of women, knowing well his times and the nature of man. There was a desperate need to intervene - not only to curtail the possibility of bad doctrine, argumentation and deception, but for the safety of the Church and its people in Christ.
I'll look forward to your thoughts on this and hope I've provided enough thought to share from what is perhaps a different way of viewing this section.
