Mainline Protestant

Older, more establishment Protestant denominations

The mainline Protestant churches are a group of Protestant denominations in the United States and Canada largely of the theologically liberal or theologically progressive persuasion that contrast in history and practice with the largely theologically conservative evangelical, fundamentalist, charismatic, confessional, Confessing Movement, historically Black church, and Global South Protestant denominations and congregations. Some make a distinction between "mainline" and "oldline", with the former referring only to denominational ties and the latter referring to church lineage, prestige and influence. However, this distinction has largely been lost to history and the terms are now nearly synonymous.
