The Archbasilica of Saint John Lateran is the Catholic cathedral of the Diocese of Rome in the city of Rome, and serves as the seat of the bishop of Rome, the pope. The only "archbasilica" in the world, it lies outside of Vatican City proper, which is located approximately four kilometres northwest. Nevertheless, as properties of the Holy See, the archbasilica and its adjoining edifices enjoy an extraterritorial status from Italy, pursuant to the terms of the Lateran Treaty of 1929. Dedicated to the Christ, in honor of John the Baptist and John the Evangelist, the place name, Laterano (Lateran) comes from an ancient Roman family (gens), whose palace (domus) grounds occupied the site; the adjacent Lateran Palace was the primary residence of the pope until the Middle Ages.

In the history of Christianity, the first seven ecumenical councils include the following: the First Council of Nicaea in 325, the First Council of Constantinople in 381, the Council of Ephesus in 431, the Council of Chalcedon in 451, the Second Council of Constantinople in 553, the Third Council of Constantinople from 680 to 681 and finally, the Second Council of Nicaea in 787. All of the seven councils were convened in what is now the country of Turkey.
In the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God. The Council rejected Nestorius' view causing many churches, centered on the School of Edessa, to a Nestorian break with the imperial church. Persecuted within the Roman Empire, many Nestorians fled to Persia and joined the Sassanid Church thereby making it a center of Nestorianism. By the end of the 5th century, the global Christian population was estimated at 10-11 million. In 451 the Council of Chalcedon was held to clarify the issue further. The council ultimately stated that Christ's divine and human nature were separate but both part of a single entity, a viewpoint rejected by many churches who called themselves miaphysites. The resulting schism created a communion of churches, including the Armenian, Syrian, and Egyptian churches, that is today known as Oriental Orthodoxy. In spite of these schisms, however, the imperial church still came to represent the majority of Christians within the Roman Empire.
Christianity is an Abrahamic monotheistic religion based on the life and teachings of Jesus as interpreted in the Bible. It is the largest religion in the world, with 2.4 billion people, known as Christians, that adhere to the religion.
