In the Solas of the Reformation: The Core Doctrines of Protestantism, the author examines and defends each one of the five great mottos of the Sixteenth Century Protestant Reformation. Martin Luther used a number of Latin mottos to express the core doctrines of Protestantism. All historic and confessional Protestants confess the basic tenets of Sola Scriptura, Solus Christus, Sola Gratia, Sola Fide, and Soli Deo Gloria. As children of the Reformation, Protestants will celebrate the biblical truths expressed in the five solas. It is fitting that Protestants study and celebrate their biblical heritage as the 500th anniversary of the Reformation occurs in 2017.
