i believe the bible has many examples of the woman's role in the church. in the new testament men lead the church that's how Jesus set it up, and the women were co-leaders/helpers to the men, they did pretty much what the men did, except as in a household God calls the man to lead (although that don't always happen
, so i think that's why most do not agree with women leading men/entire churches, since man is susposed to be the head under Christ of course, although women play a tremendous part and can certainly help them on out in their leadership of the church
in my church we have men evangelist who lead the entire church especially the men (since they have needs that a woman can not meet) and women ministry leaders who lead the women's ministry (cause we have special needs that a man can not meet). so in essence they lead the church together
