Vatican City
The name was first used in the Lateran Treaty, signed on 11 February 1929, which established the modern city-state. The name is taken from Vatican Hill, the geographic location of the state. "Vatican" is derived from the name of an Etruscan settlement, "Vatica" or "Vaticum" meaning garden, located in the general area the Romans called "vaticanus ager", "Vatican territory".
History of the Catholic Church
According to Catholic tradition, the Catholic Church was founded by Jesus Christ. The New Testament records Jesus' activities and teaching, his appointment of the twelve Apostles, and his instructions to them to continue his work. The Catholic Church teaches that the coming of the Holy Spirit upon the apostles, in an event known as Pentecost, signaled the beginning of the public ministry of the Church. Catholics hold that Saint Peter was Rome's first bishop and the consecrator of Linus as its next bishop, thus starting the unbroken line which includes the current pontiff, Pope Francis. That is, the Catholic Church maintains the apostolic succession of the Bishop of Rome, the Pope – the successor to Saint Peter.
