This basilica is the seat of the Bishop of Rome, the pope, and that, as we celebrate its dedication, we are reminded of the people the building represents: the pope and all God’s people throughout the world.
: When we celebrate the dedication of this great church, we are reminded of our own parish church where we gather to celebrate and, even more so, of our domestic church, our home, where we encounter God every day.
