Priesthood Keys, Authority, and Power

As I listened to Elder Oaks' talk about Priesthood this past conference there was one little bit that made me jump up and down and do a happy dance:

"We are not accustomed to speaking of women having the authority of the priesthood in their Church callings, but what other authority can it be?"

It immediately reminded me of reading Sheri Dew's book, Women and the Priesthood, which I reviewed and blogged a detail notes/summary/discussion.  I loved her description of the Keys/Authority/Power of the Priesthood, and it very closely echoed Elder Oaks' talk with a few exceptions noted below:

Understanding The Keys, Authority, and Power of the Priesthood
Only certain priesthood holders hold certain keys in the Church.  Keys authorize the ordinances, authority is required to perform the ordinances, those who receive ordinances have priesthood power available to them.  Those men with keys can give some women authority, in the temple women have priesthood authority.  After going to the temple, women have direct access to priesthood power.  Women don’t have keys but preside over organizations.  Sister missionaries and women in the temple have been given authority to perform works by those with keys.  Elders have power to baptize, but can’t unless given authority by someone using keys.  Ordinances and covenants are our credentials for admission into his presence.  With the exception of female temple workers, only men have authority to officiate in ordinances of priesthood.  Authority and priesthood are two different things, women have been given divine authority.

She was very clear in her book that women did not have priesthood power, but ACCESS to it.  She also was very clear that women only are given divine authority - whatever authority they hold, it is not priesthood authority.  Below I had a note with a sincere question about the difference between the two:

 (so if the priesthood means the Power of god, the Authority of God, and the Keys of God; and women receive divine authority (which is from God) what makes divine authority different?  It's a sincere question)

 I love how Elder Oaks talk further clarifies and builds on our previous knowledge and understanding.
