In the strictest sense, only those Christian denominations with an episcopal hierarchy possess cathedrals.
However, in common use, the term "cathedral" is often used for notable churches which were formerly part of an episcopal denomination.
A cathedral may in fact be a relatively small building, particularly in sparser or poorer communities.
Modern cathedrals frequently lack the grandeur of those of former times, having more focus on the functional aspects of a place of worship.
Some cathedrals were purpose-built, whilst others were formerly parochial (parish) churches which were subsequently promoted in status due to ecclesiastical requirements such as periodic diocesan reorganisation.
