For those looking for a thorough look at the founding thoughts of the Reformation, this part of a 5-book series examines one of the iconic Solas that defined the faith of the Protestants. It offers a uniquely insightful perspective by breaking the 5 tenants over 5 books to give them the proper space. A trusted route to understanding Reformation thought, this is a source of great wisdom and the source of modern Christian identity.

Historians and theologians alike have long recognized that at the heart of the sixteenth-century Protestant Reformation were the five solas: sola scriptura, solus Christus, sola gratia, sola fide, and soli Deo gloria.

These five solas do not merely summarize what the Reformation was all about but have served to distinguish Protestantism ever since. They set Protestants apart in a unique way as those who place ultimate and final authority in the Scriptures, acknowledge the work of Christ alone as sufficient for redemption, recognize that salvation is by grace alone through faith alone, and seek to not only give God all of the glory but to do all things vocationally for his glory.

2017 will mark the 500th anniversary of the Reformation. And yet, even in the twenty-first century we need the Reformation more than ever.

As James Montgomery Boice said not long ago, while the Puritans sought to carry on the Reformation, today "we barely have one to carry on, and many have even forgotten what that great spiritual revolution was all about." Therefore, we "need to go back and start again at the very beginning. We need another Reformation."
