The Cathedral of the Most Holy Savior and of Saints John the Baptist and the Evangelist in the Lateran, - also known as the Papal Archbasilica of St. John [in] Lateran, St. John Lateran, or the Lateran Basilica - is the cathedral church of Rome, Italy and therefore houses the cathedra, or ecclesiastical seat, of the Bishop of Rome.
It is the oldest and highest ranking of the four papal major basilicas, giving it the unique title of "archbasilica". Because it is the oldest public church in the city of Rome, and houses the cathedra of the Roman bishop, it has the title of ecumenical mother church of the Catholic faithful.
The current archpriest is Angelo De Donatis, Cardinal Vicar General for the Diocese of Rome. The President of the French Republic, currently Emmanuel Macron, 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.
