The Latin "Sola Scriptura" means "Scripture Only," or "Scripture alone." This was one of the distinctive features of the Protestant Reformation and signaled the Reformed departure from alleged Papal infallibility and the authority of Romish tradition. The Reformers claimed the principle of Sola Scriptura or the all-sufficiency of Scripture was the only rule of both faith and practice.
We reaffirm the inerrant Scripture to be the sole source of written divine revelation, which alone can bind the conscience. The Bible alone teaches all that is necessary for our salvation from sin and is the standard by which all Christian behavior must be measured.
We deny that any creed, council or individual may bind a Christian's conscience, that the Holy Spirit speaks independently of or contrary to what is set forth in the Bible, or that personal spiritual experience can ever be a vehicle of revelation. - Cambridge Declaration
