The Pope governs the Church through the Roman Curia. The Roman Curia consists of the Secretariat of State, nine Congregations, three Tribunals, eleven Pontifical Councils, and an assortment of offices that conduct church affairs at the highest level. The Secretariat of State, under the Cardinal Secretary of State, leads and supervises the Curia. The current Secretariat of State, Tarcisio Cardinal Bertone, acts as the Holy See's prime minister. Archbishop Dominique Mamberti, Secretary of the Section for Relations With States of the Secretariat of State acts as the Holy See's foreign minister. Bertone and Mamberti were chosen to hold these positions by Pope Benedict XVI in September 2006.
