"The Holy See" - Vatican

"The Holy See (Latin: Sancta Sedes; Ecclesiastical Latin: [ˈsaŋkta ˈsedes]; Italian: Santa Sede), also called the See of Rome, is the apostolic episcopal see of the bishop of Rome, known as the Pope, ex cathedra the universal ecclesiastical jurisdiction of the worldwide Catholic Church, and a sovereign entity of international law. Founded in the 1st century by Saints Peter and Paul, by virtue of Petrine and Papal primacy according to Catholic tradition, it is the focal point of full communion for Catholic bishops and Catholics around the world organised in polities of the Latin Church, the 23 Eastern Catholic Churches, and their dioceses and religious institutes."

"The Holy See is the universal government of the Catholic Church and operates from Vatican City State, a sovereign, independent territory. The Pope is the ruler of both Vatican City State and the Holy See. The Holy See, as the supreme body of government of the Catholic Church, is a sovereign juridical entity under international law."

"The Holy See is the organization that owns the Vatican, i.e. the smallest independent city-state in the world. They print their own passports, have their own media, and even maintain their own mail service, all for a population numbering no more than 1,000 people."

"To understand the Vatican: there are two people and two things that you need to know about: the famous pope, the incredibly confusing Holy See, The Country of Vatican City and along with that the almost completely unknown King of Vatican City.

But first the Pope: who gets a throne to sit upon and from which he acts as the Bishop for all the Catholics in Rome.

Actually all Bishops in the Catholic Church get their own thrones but because the Bishop of Rome is also the Pope his throne is special and has it's own special name: The Holy See."

"The Lateran treaty is crucial to the FCO's recognition of the Holy See as a state for the simple reason that it is the only basis upon which the Holy See itself claims to be a state."
