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.
It overlaps with other conservative Christian movements including Evangelicalism, and within Methodism specifically, the Holiness movement. Its members have stated their commitment to work to change their home denominations from within rather than establishing new ones, even if they are unable to regain full influence. It also has overlaps with Confessionalism which is identified with the belief in the importance of full and unambiguous assent to the whole of a religious movements' or denominations' teachings such as those found in Confessions of Faith which they see as accurate summaries of the teachings found in Scripture and accurately shows their distinction from other groups. Confessionalism is most visible among Lutherans known as Confessional Lutherans. The Confessing Movement places particular weight on the role of evangelism and traditional Bible teachings concerning the deity of Christ and holds conservative, historical Christian views on sexuality, especially homosexuality.
