Today, we recall the Basilica Saint John of Lateran, the Pope's own church, the Cathedral of Rome. The Lateran was chosen as the Cathedral Rome long before Saint Peter's was built. It is where the Papacy was housed for centuries before moving across the Tiber to where Vatican City now stands. The Gospel about the purification of the temple of Jerusalem is apt for today's feast. The Jerusalem temple serves as a symbol of the church of today. in the twenty-first century. It conveys both the idea of the temple's Sacredness and also the need for constant purification of the structures of our church.
