Sola scriptura (Latin for 'by scripture alone') is a Christian theological doctrine held by most Protestant Christian denominations, in particular the Lutheran and Reformed traditions, that posits the Bible as the sole infallible source of authority for Christian faith and practice. The Catholic Church considers it heterodox and generally the Orthodox churches consider it to be contrary to the phronema of the Church. While the scriptures' meaning is mediated through many kinds of subordinate authority—such as the ordinary teaching offices of a church, the ecumenical creeds, councils of the Catholic Church, or even personal special revelation—sola scriptura in contrast rejects any infallible authority other than the Bible. In this view, all non-scriptural authority is derived from the authority of the scriptures or is independent of the scriptures, and is, therefore, subject to reform when compared to the teaching of the Bible. Sola scriptura is a formal principle of many Protestant Christian denominations, and one of the five solae. It was a foundational doctrinal principle of the Protestant Reformation held by many of the Reformers, who taught that authentication of Scripture is governed by the discernible excellence of the text, as well as the personal witness of the Holy Spirit to the heart of each man. Some evangelical and Baptist denominations state the doctrine of sola scriptura more strongly: Scripture is self-authenticating, clear (perspicuous) to the rational reader, its own interpreter ("Scripture interprets Scripture"), and sufficient of itself to be the final authority of Christian doctrine. By contrast, the Protestant traditions of Anglicanism, Methodism and Pentecostalism uphold the doctrine of prima scriptura, with scripture being illumined by tradition and reason. The Methodists thought reason should be delineated from experience, though the latter was classically filed under the former and guided by reason, nonetheless this was added, thus changing the "Anglican Stool" to the four sides of the Wesleyan Quadrilateral.
