The Papal Archbasilica of St. John Lateran, commonly known as St. John Lateran's Archbasilica, St. John Lateran's Basilica, and just The Lateran Basilica, is the cathedral church of the Diocese of Rome and the official ecclesiastical seat of the Bishop of Rome, who is the Pope. 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 baptistery 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.  Today’s feast celebrates our link with Pope Leo XIV and the universality of the Church and this is why it takes precedence over the liturgy for the 32^nd Sunday of Ordinary time.
