The "parish church" of all of us, I guess. And the seat of the Bishop of Rome. American Catholic:
Unlike the commemorations of other Roman churches (St. Mary Major, Sts. Peter and Paul), this anniversary is a feast. The dedication of a church is a feast for all its parishioners. St. John Lateran is, in a sense, the parish church of all Catholics, for it is the pope's parish, the cathedral church of the Bishop of Rome. This church is the spiritual home of the people who are the Church.More photos, from last year's post.
