St. Mary's Cathedral
Significance of a Cathedral
A cathedral is the home of the bishop. Since the bishop is a successor to the Apostles, it is the home of Christ's Church, just as the Vatican is the universal home of the Church on Earth. The Church of a certain area, a diocese, can claim it as their very own, no matter where they live in the diocese. It holds within it the Cathedra, the throne of the bishop, representing the power given him by Christ.
