The Papal Archbasilica of St. John in Lateran, commonly known as St. John Lateran Archbasilica, St. John Lateran Basilica, St. John Lateran, or simply the Lateran Basilica, is the cathedral church of Rome, Italy and therefore houses the cathedra, or ecclesiastical seat, of the Roman Pontiff (Pope).
The large Latin inscription on the façade reads: Clemens XII Pont Max Anno V Christo Salvatori In Hon SS Ioan Bapt et Evang; which is a highly abbreviated inscription which translates to: "Pope Clement XII, in the fifth year [of his Pontificate], dedicated this building to Christ the Savior, in honor of Saints John the Baptist and John the Evangelist". The inscription indicates, along with its full title that the archbasilica was originally dedicated to Christ the Savior and, centuries later, co-dedicated to St. John the Baptist and St. John the Evangelist. in English is Archbasilica of the Most Holy Savior and Saints John the Baptist and the Evangelist in the Lateran,
As the Cathedral of the Pope qua Bishop of Rome, it ranks superior to all other churches of the Roman Catholic Church, including St. Peter's Basilica, and therefore it alone is titled "Archbasilica" among all other basilicas. It is the oldest of and has precedence among the four papal major basilicas, all of which are in Rome, because it is the oldest church in the West and houses the cathedra of the Roman Pontiff. It has the title of ecumenical mother church of the Roman Catholic faithful.
The current archpriest is Agostino Vallini, Cardinal Vicar General for the Diocese of Rome. The President of the French Republic, currently François Hollande, is ex officio the "first and only honorary canon" of the archbasilica, a title that the heads of state of France have possessed since King Henry IV.
