Catholic theology
Catholic belief holds that the church exists both on earth and in heaven simultaneously, and thus the Virgin Mary and the saints are alive and part of the living church. Prayers and devotions to Mary and the saints are common practices in Catholic life. These devotions are not worship, since only God is worshiped. The church teaches that the saints "do not cease to intercede with the Father for us. ... So by their fraternal concern is our weakness greatly helped."
List of religious sites
Rome is the place from which Catholics believe the one, holy, catholic and apostolic church were formally founded and begun by St. Peter (whom they consider to be the "Prince of the Apostles") as the appointed successor and first vicar of Christ. Thus while the Holy Sepulchre is still the most sanctified of places for Catholics, the Vatican is an extremely sacred place to the faithful (those of the Latin Church, as well as the Churches "sui iuris") as the seat of their supreme authority on Earth. Important papal territories include the four major basilicas (L.: "Basilica maior", pl. "-es"; excluding St. Peter's) – namely the Archbasilica of St. John Lateran (the ecumenical Catholic mother church), St. Peter's Basilica, the Basilica of St. Paul Outside the Walls (containing the tomb of Paul the Apostle), and the Basilica di Santa Maria Maggiore.
