What Makes a Cathedral a Cathedral?

A cathedral is not defined by size, grandeur, or architecture—it is defined by one ecclesiastical function:

A cathedral is the church that contains the cathedra (throne) of a bishop.

The Essential Criteria

1. The Cathedra: Latin for "chair/throne." Symbolizes the bishop's teaching authority and pastoral governance of a diocese (geographic jurisdiction).
2. The Bishop: Resident diocesan bishop (or archbishop/metropolitan). Without a bishop's seat, it's just a large church.
3. The Diocese: The cathedral is the mother church of the diocese—administrative center, ordination site, chrism mass, synod venue.

Common Associated Features (But Not Definitive)

• Chapter of Canons: College of priests advising bishop; led by Dean (or Provost). Manages cathedral fabric/liturgy.
• Scale & Architecture: Often large, Gothic/Romanesque/Modern, with nave, transept, choir, ambulatory, crypt. But small cathedrals exist (e.g., St. Asaph, Wales – tiny; Sacred Heart, Raleigh – modest).
• Status: "Cathedral" status granted by papal bull (RC) or synod/charter (Anglican, Orthodox, Lutheran).
• Co-Cathedrals / Pro-Cathedrals: Two cathedrals in one diocese (historical); temporary seat.

What It's NOT

• Any big church (e.g., Basilica of the National Shrine in DC – minor basilica, not cathedral).
• A parish church (serves local neighborhood; priest, not bishop).
• A monastery/abbey church (abbot, not bishop—unless abbey is also a diocese, rare).

Denominations With Cathedrals

Roman Catholic, Eastern Orthodox, Oriental Orthodox, Anglican/Episcopal, Lutheran (some), Methodist (some – "cathedral" as honorary).

Bottom line: If the bishop's chair is there, it's a cathedral. If not, it isn't—no matter how magnificent.
