Hi, Annie,
Maybe you should ask whoever posted that statistic where they got it from. Then you could make the point that bapmom advises, that even if a majority have that view, that doesn't make it right.
You can ask them this: How can the Bible say that a man is to be the spiritual head of the home and yet we can have women who are spiritual heads in the church?
If what Paul said was just cultural for that time, why not point out that then we could say the passages against homosexuality are just cultural as well. Where is the line drawn? I think cultural issues are clear from the context, and the teaching on women is not one of them.
In fact, I've heard somewhere that early Christianity treated women with much more equality than the surrounding culture. You might want to check into that. So not having woman pastors is not a restriction of early Christianity but results from the biblical role and model given in scripture.
