The Churches of Christ, also commonly known as the Church of Christ, is a loose association of autonomous Christian congregations located around the world. Typically, their distinguishing beliefs are that of the necessity of baptism for salvation and the prohibition of musical instruments in worship. Many such congregations identify themselves as being nondenominational. The Churches of Christ arose in the United States from the Restoration Movement of 19th-century Christians who declared independence from denominations and traditional creeds. They sought "the unification of all Christians in a single body patterned after the original church described in the New Testament."

Christianity is an Abrahamic monotheistic religion based on the life and teachings of Jesus Christ. It is the world's largest and most widespread religion with roughly 2.4 billion followers, comprising around 31.2% of the world population. Its adherents, known as Christians, are estimated to make up a majority of the population in 157 countries and territories. Christians believe that Jesus Christ is the Son of God, whose coming as the Messiah was prophesied in the Hebrew Bible and chronicled in the New Testament.
