John Paul II denied the Power of the Keys.  The Church was given the power to loose and bind.  That power doesn't stop with female genitalia.  

There would be no Church to exclude women from the priesthood if a woman hadn't agreed to birth Jesus.  We need women to provide a future for the very Church that denies them entrance into the sanctuary.  That is women's call:  to insure the future, to insure evolutionary progress.  Mary certainly insured the evolutionary progress of Judaism.
