A Christian church is a group of people who share a set of beliefs, practices, and identities. They usually meet in one particular location called a cathedral, temple, tabernacle, or simply a church building.
A church group follows a set of teachings and traditions. A group of Christian churches that use the same name and share the same beliefs is called a denomination.
A church that is not part of a larger group is usually called nondenominational.
There are estimated to be over 41,000 denominations worldwide. They mostly fall within three general groups: Orthodox, Catholic, and Protestant Churches.
