Dedication of St. John Lateran

Most Catholics think of St. Peter’s as the pope’s main church, but they are wrong. St. John Lateran is the pope’s church, the cathedral of the Diocese of Rome where the Bishop of Rome presides.
The first basilica on the site was built in the fourth century when Constantine donated land he had received from the wealthy Lateran family. That structure and its successors suffered fire, earthquake and the ravages of war, but the Lateran remained the church where popes were consecrated until the popes returned from Avignon in the 14th century to find the church and the adjoining palace in ruins.
Pope Innocent X commissioned the present structure in 1646. One of Rome’s most imposing churches, the Lateran’s towering facade is crowned with 15 colossal statues of Christ, John the Baptist, John the Evangelist and 12 doctors of the Church. Beneath its high altar rest the remains of the small wooden table on which tradition holds St. Peter himself celebrated Mass.
Comment:

Unlike the commemorations of other Roman churches (St. Mary Major, August 5; Sts. Peter and Paul, November 18), this anniversary is a feast. The dedication of a church is a feast for all its parishioners. In a sense, St. John Lateran is the parish church of all Catholics, because it is the pope's cathedral. This church is the spiritual home of the people who are the Church.
Quote:

"What was done here, as these walls were rising, is reproduced when we bring together those who believe in Christ. For, by believing they are hewn out, as it were, from mountains and forests, like stones and timber; but by catechizing, baptism and instruction they are, as it were, shaped, squared and planed by the hands of the workers and artisans. Nevertheless, they do not make a house for the Lord until they are fitted together through love" (St. Augustine, Sermon 36).
