The Pope lives in the Vatican, a country in Rome. The Pope is the head of state of the Vatican. After being elected, he holds office for life and cannot be removed.

In the Vatican, a country where politics and religion are integrated, the Pope is also the highest head of state, with legislative power and judicial power, and can enact and abolish church laws and regulations. In the hearts of believers, the Pope's interpretation of any doctrine is always right. Francis changed the style that successive popes rarely made big moves in government affairs, and made full use of his authority to rectify the church bank and reform the professional structure of priests.
