Nonconformity to the world, also called separation from the world, is a Christian doctrine based on Romans 12:2,[1][2] 2 Corinthians 6:17[3] and other verses of the New Testament that became important among different Protestant groups, especially among Wesleyans and Anabaptists. The corresponding German word used by Anabaptists is Absonderung.[4] Nonconformity is primarily expressed through the practices of plain dress and simple living.
