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.
Evangelicalism in the United States
In the United States, evangelicalism is an umbrella group of Protestant Christians who believe in the necessity of being born again, emphasize the importance of evangelism, and affirm traditional Protestant teachings on the authority and the historicity of the Bible. Nearly a quarter of the US population, evangelicals are diverse and drawn from a variety of denominational backgrounds, including Baptist, Mennonite, Methodist, Holiness, Pentecostal, Reformed and nondenominational churches.
