Women's role in the church

My husband and I had an interesting day in church on Sunday. We walked out of our Sunday School class. For reasons unknown to either of us, one of the female members was teaching the class that day. (Our class is large and co-ed.) I think what upset me the most was all of the men sitting in the class, willing to be taught by a woman. I'm not sure if this is ignorance as to what the Bible teaches about women in leadership/teaching roles or whether they don't care what the Bible says. Either way, we were very saddened and plan to start looking for another class to attend, if the Lord desires to keep us in this town. (Keith has applied for a couple of positions back in GA, so we'll see what the Lord has.)
