The Confessing Movement is a largely lay-led theologically conservative Christian movement that opposes the influence of theological liberalism and theological progressivism currently within several mainline Protestant denominations and seeks to return those denominations to its view of orthodox doctrine or to form new denominations and disfellowship (excommunicate) them if the situation becomes untenable. Those who eventually deem dealing with theological liberalism and theological progressivism within their churches and denominations as not being tenable anymore would later join or start Confessional Churches and/or Evangelical Churches that continue with the traditions of their respective denominations and maintaining orthodox doctrine while being ecclesiastically separate from the Mainline Protestant denominations. Youth aligned with the Confessing Movement have viewed their project as being an 'Operation Reconquista'.
