High Quality Content by WIKIPEDIA articles! Mainline or mainline Protestant also sometimes called mainstream denominations are those that comprised the vast majority of American Christianity from the colonial era until the early 1900s. Most were brought to America by their respective historic immigrant groups. Today, most are rooted in the Northern United States. As a group they have maintained theologies that stress social justice concerns together with personal salvation and evangelism. They have been credited with leading the fight for social causes such as racial justice and civil rights, equality for women, rights for the disabled and other key issues. Many of the issues that such groups have advocated for have been embraced by American law and society, but at the same time mainline denominations have been somewhat marginalized. In addition, mainline churches and laity founded most of the leading educational institutes in the US.In typical usage, the term mainline is contrasted with evangelical. Mainline churches tend to be more liberal in terms of theology and political issues. This places them to the ideological left of the evangelical and fundamentalist churches.
