In the Christian tradition, there is a division of churches (buildings in which worship is carried out). So, you can highlight the usual parish churches, cathedrals and cathedrals.
Most often, cathedrals are called spacious, majestic Christian churches. In addition, some cathedrals have the status of cathedrals. This means that in a particular cathedral there is a chair of the ruling bishop (bishop). The pulpit is understood as a certain elevation in the middle of the temple, on which the ruling bishop stands during the divine service. Simply put, a cathedral is a temple in which the head of the diocese (metropolitanate) carries out his ministry.
Cathedrals are the main temples of the ecclesiastical area (diocese). Some cathedrals have or have had patriarchal status. For example, the Cathedral of Christ the Savior in Moscow, the Epiphany Cathedral in Yelokhovo (he was patriarchal until 1991). Accordingly, the patriarch of Moscow and All Russia often carries out his ministry in these churches.
It is noteworthy that cathedrals are called not only Orthodox, but also Catholic churches in which the ruling bishops serve. It is worth noting that services are held daily in such churches. Many priests and deacons carry out their ministry in cathedrals. The ruling bishop on Sundays or other holidays leads the divine service.
Many cathedrals are very ancient. For example, the Orthodox cathedrals of Vladimir, Suzdal, Moscow. Other cathedrals became such relatively recently (these churches were built specifically for the main place of ministry of the ruling bishop).
