This is a good explanation (even though it's wikipedia...) Evangelicalism - Wikipedia, the free encyclopedia Other categories: Fundamentalism (to the right of evangelicalism) Conservative (generally synonymous with evangelical) Mainline (generally middle-of-the-road to liberal) Liberal (sometimes lumped in with mainline) In general, as one goes from liberal to fundamentalist, one becomes more "orthodox" in theology. On the fundamentalist side, other cultural distinctives arise, such as not attending movies, dances, etc. Some representative denominations/groups: Fundamentalist: independent fundamental Baptist churches, many pentecostal churches Conservative/Evangelical: Assemblies of God, Southern Baptist Convention, Wesleyan Church, Presbyterian Church in America, many nondenominational churches, Lutheran Church (Missouri Synod) Mainline: United Methodist Church, Presbyterian Church (USA), American Baptist Churches, Evangelical Lutheran Church in America, the Episcopal Church, United Church of Christ Liberal: United Church of Christ, Unitarian Universalists Of course, there is variance in theological orienation within each denomination/group/church. For instance, you will find some conservative Methodists and some relatively liberal Southern Baptists. In the Episcopal Church this is also common, as the conservative, evangelical wing of the denomination and the liberal wing of the denomination have clashed over the issue of homosexuality. Similar conflicts are occurring in the ELCA, UMC, and PCUSA.
