The Church of the Nazarene is an evangelical Christian denomination that emerged from the 19th-century Holiness movement in North America. With its members colloquially referred to as Nazarenes, it is the largest Wesleyan-holiness denomination in the world. At the end of September 2014, the Church of the Nazarene had 2,295,106 members in 29,395 churches in 159 different "world areas". The Church of the Nazarene uses "world area" to describe countries and areas that are a part of a country, but may be known by a different name. More than 20 of the denomination's 159 world areas fall into this category, such as Guam, a U.S. territory on the Asia-Pacific Region.
