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
The word "evangelical" has its etymological roots in the Greek word for "gospel" or "good news": "euangelion", from "eu" "good", "angel"- the stem of, among other words, "angelos" "messenger, angel", and the neuter suffix -"ion". By the English Middle Ages, the term had expanded semantically to include not only the message, but also the New Testament which contained the message, as well as more specifically the Gospels, which portray the life, death, and resurrection of Jesus. The first published use of "evangelical" in English was in 1531, when William Tyndale wrote "He exhorteth them to proceed constantly in the evangelical truth." One year later Sir Thomas More wrote the earliest recorded use in reference to a theological distinction when he spoke of "Tyndale [and] his evangelical brother Barns".
