Papal infallibility
Evangelical churches do not believe in papal infallibility for reasons similar to those of Methodist and Reformed Christians. Evangelicals believe that the Bible alone is infallible or inerrant. Most evangelical churches and ministries have statements of doctrine that explicitly say that the Bible, composed of the Hebrew Scriptures and the New Testament, is the sole rule for faith and practice. Most of these statements, however, are articles of faith that evangelicals affirm in a positive way, and contain no reference to the papacy or other beliefs that are not part of evangelical doctrine.
Christianity in the United States
Note that the term "Evangelical" does not equal Fundamentalist Christianity, although the latter is sometimes regarded simply as the most theologically conservative subset of the former. The major differences largely hinge upon views of how to regard and approach scripture ("Theology of Scripture"), as well as construing its broader world-view implications. While most conservative Evangelicals believe the label has "broadened" too much beyond its more limiting traditional distinctives, this trend is nonetheless strong enough to create significant ambiguity in the term. As a result, the dichotomy between "evangelical" vs. "mainline" denominations is increasingly complex (particularly with such innovations as the "Emergent Church" movement).
