There are about 40,000 different Christian denominations. It's not even something that can be counted and kept track of. However, they can be roughly split into five major groups:
- The Catholic Church
- The Eastern Churches (Orthodox, Oriental Orthodox, Church of the East)
- "Mainline" Protestant and Anglican churches
- Evangelical (non-Pentecostal)
- Pentecostal churches
These later two categories include a number of "non-denominational" or independent congregations. The first wave of "non-denominational" churches are in fact the third wave of the pentecostal movement. Other independent congregations tend to be evangelical, and while may not belong to a denomination per se, often do belong to various parachurch organizations or adhere to a common set of standards and beliefs with other similar evangelical churches. Some megachurches, by engaging in 'church planting' set themselves up as a sui iuris denomination while maintaining the "non-denominational" title.
