The Restorationist Movement is a religious movement that emerged in the early 19th century, primarily in the United States. It sought to restore the original teachings and practices of early Christianity, emphasizing a return to the Bible as the sole authority in faith and practice. This movement aimed to unify Christians by rejecting denominational divisions and promoting a simple, New Testament-based faith. Key figures in the movement include Thomas Campbell and his son Alexander Campbell, who founded the Disciples of Christ and the Churches of Christ. The movement has influenced various Christian denominations and continues to advocate for a return to primitive Christianity and a focus on community and fellowship.
