Interesting that your paradigm of family life defaulted to parental permission. I had more in mind a relationship between brothers and sisters. 

It's a circular argument to say that the Church has no authority because it claims it has no authority. Eventually, absent a clear Scriptural directive to the contrary, I believe the Church will indeed  accept the authority to ordain women. 

In any event, since neither you nor I are the Holy Spirit and can predict the future, we'll have to leave it there for now. I'm moving on.
