If role distinctions for men and women are rooted in God's created order, why don't you apply the rules everywhere in secular life as in the home and the church?
John Piper and Wayne Grudem (edited by David Kotter)
As we move out from the church and the home we move further from what is fairly clear and explicit to what is more ambiguous and inferential. Therefore our emphasis moves more and more away from specific role recommendations (like the ones made in Scripture), and instead focuses on the realization of male and female personhood through the more subjective dimensions of relationship like demeanor, bearing, attitudes, courtesies, initiatives, and numerous spoken and unspoken expectations.
We believe the Bible makes clear that men should take primary responsibility for leadership in the home and that, in the church, the primary teaching and governing leadership should be given by spiritual men. We take this to be a Biblical expression of the goodness and the wisdom of God concerning the nature of leadership in these roles and the nature of manhood and womanhood. That is, rather than leaving to us to judge for ourselves whether mature manhood and womanhood would be preserved and enhanced through the primary leadership of men or women in these spheres, God was explicit about what would be good for us. However, when it comes to all the thousands of occupations and professions, with their endlessly varied structures of management, God has chosen not to be specific about which roles men and women should fill. Therefore we are not as sure in this wider sphere which roles can be carried out by men or women in ways that honor the unique worth of male and female personhood. For this reason we focus (within some limits) on how these roles are carried out rather than which ones are appropriate.
