The archbasilica and Lateran Palace were re-dedicated twice. Pope Sergius III dedicated them to Saint John the Baptist in the 10th century in honor of the newly consecrated baptistry of the archbasilica. Pope Lucius II dedicated them to John the Evangelist in the 12th century. Thus, Saint John the Baptist and Saint John the Evangelist became co-patrons of the archbasilica, while the primary Patron is still Christ the Savior, as the inscription in the entrance indicates and as is traditional for patriarchal cathedrals. Consequently, the archbasilica remains dedicated to the Savior, and its titular feast is the Feast of the Transfiguration. The archbasilica became the most important shrine of the two Saint Johns, albeit infrequently jointly venerated. In later years, a Benedictine monastery was established in the Lateran Palace, and was devoted to serving the archbasilica and the two saints.
