I've been involved in a small debate over at iMonk about women in church leadership. The question at hand is women leading churches, and Paul's prohibition thereof. I have given the relevant Scriptures.
Thinking about the discussion more, I wonder how much the opposing side is driven by the notion of "Pastor as CEO". That is, most every manager wants to be CEO, and city councilman wants to be mayor (or president of the USA). It is a sign of accomplishment, to oneself and the world. The fulfillment of one's career (which may be reasonable, or sinful/prideful).
This is where the passage in Matthew 20:25 comes in. A leader of the church is not a position of power to be envied. It is a position of great responsibility (see James 3:1). It is a position of total servitude (often the Greek word "slave" is translated "servant").
Forbidding women from leadership is not a "glass ceiling". It is the duty of men to serve others, and to protect women from the onerous burden of Christian leadership. To allow a woman to lead one's church is not "open minded", it is men slacking in their duty, a grave disservice to the woman, and dishonoring God.
