For some quick definitions (in usual satirical mode):
Reformed Christianity: The progression of historic orthodox Christianity that is in submission to Christ through His external authority, the Bible interpreted through the historic Christian Church.
Liberalism: The secular progression of the religion of the Self that views the Self as the primary interpretive authority of reality (whether it admits or not).
Fundamentalism: Really conservative, and even legalistic, liberalism.
Evangelicalism: Moderately conservative liberalism.
Emerging Church: Full blown liberalism that views itself as more moderate than liberalism.
All of these incorporate some orthodoxy into them, but often have radically different definitions or are merely a hybrid between Christianity and the religion of the Self.
