Martin Luther was a German priest, theologian, author, hymnwriter, professor, and Augustinian friar. Luther was the seminal figure of the Protestant Reformation, and his theological beliefs form the basis of Lutheranism. He is regarded as one of the most influential figures in Western and Christian history.

Sola scriptura 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.
