The Middle Ages
The official dedication of the Basilica and the adjacent Lateran Palace was presided over by Pope Sylvester I in 324, declaring both to be Domus Dei or "House of God." In its interior, the Papal Throne was placed, making it the Cathedral of the Bishop of Rome. In reflection of the basilica's claim to primacy in the world as "mother church", the words Sacrosancta Lateranensis ecclesia omnium urbis et orbis ecclesiarum mater et caput (meaning "Most Holy Lateran Church, of all the churches in the city and the world, the mother and head") are incised in the front wall between the main entrance doors.
The Lateran Palace and basilica have been rededicated twice. Pope Sergius III dedicated them to Saint John the Baptist in the 10th century in honor of the newly consecrated baptistry of the Basilica. Pope Lucius II dedicated the Lateran Palace and basilica to Saint John the Evangelist in the 12th century. However, St. John Baptist and St. John the Evangelist are regarded as co-patrons of the Cathedral, the chief patron being Christ the Saviour himself, as the inscription in the entrance of the Basilica indicates, and as is tradition in the patriarchal cathedrals.
Thus, the Basilica remains dedicated to the Saviour, and its titular feast is the Transfiguration. That is why sometimes the Basilica will be referred to by the full title of Archbasilica of the Most Holy Saviour and of Sts. John Baptist and John Evangelist in the Lateran. The church became the most important shrine in honor of the two saints, not often jointly venerated. In later years, a Benedictine monastery was established at the Lateran Palace, devoted to serving the basilica as a devotional to the two saints.
Every pope from Miltiades occupied the Lateran Palace until the reign of the French Pope Clement V, who in 1309 decided to transfer the official seat of the Catholic Church to Avignon, a papal fief that was an enclave within France. The Lateran Palace has also been the site of five Ecumenical councils. See Lateran councils.

Famous quotes related to the middle ages:
“Until the end of the Middle Ages, and in many cases afterwards too, in order to obtain initiation in a trade of any sort whatever—whether that of courtier, soldier, administrator, merchant or workman—a boy did not amass the knowledge necessary to ply that trade before entering it, but threw himself into it; he then acquired the necessary knowledge.”
—Philippe Ariés (20th century)
