I'm not making the claim that women are equal to men as far as the institutional Church is concerned. That would be crazy to do so. It's obvious that ordained males have far more opportunities to exercise "power" in the Church than females as well as married males. 

My claim is why does anyone care? The whole notion I am putting forward that Sosa undermines with his quote is that power in the Church is INCONSEQUENTIAL to fully participating in the Church. 

If you conceive of the Church primarily as an earthly institution with the mission of making an impact in the world then I get why you care about everyone participating in the governing/power structures of the Church.

If you conceive of the Church primarily as the mystical body which makes Christ present and available to all people through the ministry of the sacraments then power/governance is totally unrelated to participation. 

Choose your definition of the Church and follow the logical conclusions about participating in it.
