While Joseph Smith taught that any person with a testimony of Christ is a [[prophet]], the LDS church remains a hierarchial organization with a president-prophetPresident/Prophet, usually assisted by two "Counselors", who alone possesses the "keys" to all prophetic power. Most members of the LDS church believe that their current president, Thomas S. Monson (as of 2008), is the sole person authorized to speak definitively for God on the earth today. Below this "First Presidency" are twelve "Apostles," who are also considered "prophets, seers, and revelators," but who do not exercize the prerogatives held by the president.
