Christian Restorationism is a religious movement that seeks to return Christianity to its original teachings and practices as found in the New Testament. Advocates believe that many modern Christian denominations have deviated from the true faith, and they aim to restore the church to its early, apostolic form. This movement emphasizes the authority of the Bible and often rejects traditions that are not explicitly supported by scripture. Key figures in this movement include Alexander Campbell and Barton W. Stone, who were instrumental in the early 19th century in promoting the idea of unity among Christians. Restorationists often focus on practices such as baptism by immersion and the observance of the Lord's Supper, viewing these as essential to the faith.
