You asked about the passage in Timothy. So, I wrote  "For 1 Tim 2:12". I did not say that I agree with everything Witherington writes. However, as for the "saved in childbearing" passage, there are numerous different interpretations about that, even among Adventists. 

Witherington gives you one that is rather widely held by conservative Christians, and has been so throughout Christian history. I tend to agree with him on that one. I do not accept the interpretation of some among us, who argue that women in general need to bear children in order to be saved (yes, there are people who think so). That is works-oriented doctrine of salvation, and as far as I'm concerned, total rubbish.

You wrote "The doctrine of equality is rooted in man's imagination, not in scripture." to Monte. That is not true. It is based on pre-Fall condition as described in Geneses 1-2. Subordination passages relate to marriage domain in the post-Fall condition, not outside it. Contra some anti-WO people.
