This question presupposes that the pope only has three jobs or roles. Depending on how you define a job or role the list may be longer or shorter.
In generally the pope is the head of the Roman Catholic Church.
The current titles for Pope Benedict XVI are:
* Bishop of Rome
* Vicar of Christ
* Successor of the Prince of the Apostles
* Supreme Pontiff of the Universal Church
* Primate of Italy
* Archbishop and Metropolitan of the Roman Province
* Sovereign of the State of the Vatican City
* Servant of the Servants of God
Many of these are laudatory but some have separate and specific responsibilities, and it is election to "Bishop of Rome" that actually confers papacy. Sovereign of the State of the Vatican City is a political title and confers him as a head of state, albeit for a very small country-Vatican City.
Most would agree that Popes have three major roles:
Politically and Diplomatically they are the head of state for Vatican City.
Managerially they run the Roman Catholic Church, an extensive global organization.
Theologically they are the ultimate authority on theological matters for the Roman Catholic Church.
A complete description of each of these roles is beyond this answer, but Wikipedia has a good section that covers it. http://en.wikipedia.org/wiki/Pope
in my own words i think that the pope teach people about god and praying to the people

Pope Benedict IX was pope three times and was, perhaps, the most vile and disgusting individual to ever fill the shoes of Saint Peter.
