Orathaic, here's the footnote to verse 15 from the New Living Translation:
2:15) Or-- will be saved by accepting their role as mothers, or-- will be saved by the birth of the Child. Another thing to remember is that Paul is giving women advice for his generation--wisdom, not necessarily a commandment from God. See I Cor 7:25, where Paul states: "Now regarding your question about the young women who are not yet married. I do not have a command from the Lord for them. But the Lord in his mercy has given me wisdom that can be trusted, and I will share it with you."
Conclusions: 1) Women are saved by the birth of the Child, Jesus, but in a special sense, since only women are capable of giving birth. 2) Paul may well just be giving advice to the women of his day. The Bible does teach that the man is the head of the household, but that the husband and wife should "submit yourselves one to another," and compares the love that the husband should give the wife to Jesus' love, a sacrificing love, willing to die to save the bride.
