A church is a building that was constructed to allow people to meet to worship together. These people are usually Christians, or influenced by Christianity. Other religious groups also call their religious buildings a church, such as Raelists, Wiccans and Scientologists.
Depending on the number of people that are in a community, the churches come in different sizes. Small churches are called chapels. The churches in a particular geographical area form a group called the diocese. Each diocese has a cathedral. In most cases, the cathedral is a very big church. Cathedrals are the seat of bishops.
