The Pope governs the Church through the Roman Curia. The Roman Curia consists of the Secretariat of State, nine Congregations, three Tribunals, 11 Pontifical Councils, and a complex of offices that administer church affairs at the highest level. The Secretariat of State, under the Cardinal Secretary of State, directs and coordinates the Curia. The current incumbent, Tarcisio Cardinal Bertone, is the Holy See's equivalent of a 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 have been named in their respective roles under by Pope Benedict XVI in September 2006.
