Christian Church (Disciples of Christ)

The Christian Church (Disciples of Christ) is a mainline Protestant Christian denomination in the United States and Canada. The denomination started with the Restoration Movement during the Second Great Awakening, first existing during the 19th century as a loose association of churches working towards Christian unity, then slowly forming quasi-denominational structures through missionary societies, regional associations, and an international convention. In 1968, the Disciples of Christ officially adopted a denominational structure at which time a group of churches left to remain nondenominational.

The denomination is referred to by several versions of its full name, including "Disciples of Christ", "Disciples", "Christian Church", and "DOC". The Christian Church was a charter participant in the formation of the World Council of Churches (WCC) and of the Federal Council of Churches (now the National Council of Churches), and it continues to be engaged in ecumenical conversations.

The Disciples' local churches are congregationally governed. In 2008 there were 679,563 members in 3,714 congregations in the United States and Canada. By 2015, this number had declined to a baptized membership of 497,423 in 3,267 congregations, of whom about 306,905 were active members, while approximately 177,000 attended Sunday services each week. In 2018, the denomination reported 380,248 members with 124,437 people in average worship attendance. By 2022, membership had dropped to 277,864 members, 89,894 of whom attended worship on average.
