The priesthood can work many miracles and do many things if the person holding it has the faith and is worthy for example here is a talk given by Elder Holland of the Seventy...http://lds.org/pages/mormon-messages-gallery?lang=eng
Enjoy and see how the priesthood was used and the faith that was required. I know it works and the priesthood is the power and authority to act in Gods name.
