Titus 2
4 and so train the young women to love their husbands and children,
5 to be self-controlled, pure, working at home, kind, and submissive to their own husbands, that the word of God may not be reviled.

1 Peter 3
5 For this is how the holy women who hoped in God used to adorn themselves, by submitting to their own husbands,
6 as Sarah obeyed Abraham, calling him lord. And you are her children, if you do good and do not fear anything that is frightening.

1 Timothy 2
9 likewise also that women should adorn themselves in respectable apparel, with modesty and self-control, not with braided hair and gold or pearls or costly attire,
10 but with what is proper for women who profess godliness—with good works.
11 Let a woman learn quietly with all submissiveness.
12 I do not permit a woman to teach or to exercise authority over a man; rather, she is to remain quiet.
13 For Adam was formed first, then Eve;
14 and Adam was not deceived, but the woman was deceived and became a transgressor.
15 Yet she will be saved through childbearing—if they continue in faith and love and holiness, with self-control.

1 Corinthians 14
33 For God is not a God of confusion but of peace. As in all the churches of the saints,
34 the women should keep silent in the churches. For they are not permitted to speak, but should be in submission, as the Law also says.
35 If there is anything they desire to learn, let them ask their husbands at home. For it is shameful for a woman to speak in church.

A Sunday school lesson sparked some interest into the last verses here. Can women really speak in church? Is this somehow another example of what was accepted in the bible times?
It seems to me that the spirit of the teachings regarding women is one thing - submission. We are to submit to God first and to our own husbands second and never, ever, ever (unless it would cause us to sin) step out of those boundaries... But I really don't know.
