The Cathedral of Christ the King, dedicated in 1927 and rededicated in 2005 after a major restoration serves as the official seat of the Diocese of Superior.
The cathedral is the primary or "mother church" of the diocese, even though it was not the oldest or first church established (cf. St. Joseph in La Pointe).
As the diocesan cathedral, the Cathedral serves as the church where the Bishop.
The cathedral of the Diocese of Superior, like most cathedrals in the United States, is also a parish church, with its own local community of Catholic faithful who come together for daily and weekend Masses. The rector of the Cathedral (equivalent to pastor), handles the day to day administration of the parish. Father Ricci has been the rector of the cathedral since 2009.
In the canon law of the Catholic Church, the relationship of the bishop to his cathedral is often compared to the relationship of a parish priest to the parochial church.
