1tim2 11 Let a woman learn in silence with all submission. 12 And I do not permit a woman to teach or to have authority over a man, but to be in silence. 13 For Adam was formed first, then Eve. 14 And Adam was not deceived, but the woman being deceived, fell into transgression. 15 Nevertheless she will be saved in childbearing if they continue in faith, love, and holiness, with self-control.
Emphasis mine.
In another book Paul makes it very clear that when he says "I" he does not mean "The Lord."
My personal belief, and I am not an M. Div., is that Paul had this rule in Ephasus because of discipline problems he encountered there. Ephasus was a center of Diana worship. It is not inconceivable that women converts were having trouble accepting their new lowered status as equals to the men in the Church and Paul found this approach important for discipline.
I will not hold people who disagree with this interpretation as unChristian. I have heard their arguments and find them (both men and women) to be thoughtful and based on their notion of Biblical fidelity.
Shalom.
