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.
Evangelical Anglicanism
By 1844, two-thirds of Episcopal clergy were evangelical. Nevertheless, the growing influence of the Anglo-Catholic Oxford Movement on Episcopal Church leaders worried evangelicals. They experienced a loss of confidence in the church's institutions after 1844 when the church's General Convention refused to label the Oxford Movement a heresy. Their own attempts to stem the tide through heresy trials ultimately failed as well. In response, evangelicals chose to form their own distinctly evangelical Episcopal voluntary societies to promote education and evangelism, such as the Protestant Episcopal Society for the Promotion of Evangelical Knowledge (which later merged with what is now known as the Episcopal Evangelism Society) and the American Church Missionary Society (which was modelled on the English society).
