Totally agree with your assessment of the purpose of power/authority according to the Gospels. I am totally open to the idea of women being the heads of Vatican dicasteries and other important ministries at macro and micro levels in the Church. I would welcome women being in charge of Vatican financials, special commissions, and many other things.

On a more personal level I really have powerful women parish ministry leaders to thank for my own personal relationship with Christ and the Church. Without my female high school youth minister's vision, outreach, and care I probably would not practice my faith today.

That said, the relationship between ordained ministry and "authority" in the Church is mostly accidental. Only at the level of bishop does governance enter the equation as specific duty in Holy Orders. Nevertheless the overwhelming dynamic of ordained ministry is not leadership but the making present of Christ in the sacraments for the salvation of souls.
