Concordia Publishing House has just published a new biography of Frederick the Wise, the powerful Duke of Saxony who was Luther’s protector. I was able to read an advance copy, and it is excellent. The book, by the multi-faceted biographer Sam Wellman, puts the reader in the middle of the life and times of late Medieval Saxony, with all of the intrigue and high-stakes politics that characterized the Holy Roman Empire. And Frederick emerges as a formidable figure, someone the Emperor relied on so much that he dared not arrest the Duke’s pet theologian. Also, contrary to other things I had read, Frederick was very much a “Lutheran” who appreciated above all Luther’s emphasis on the Scriptures. After the jump, a link to the book, and the endorsement I wrote for it.My endorsement for Sam Wellman, Frederick the Wise: Seen and Unseen Lives of Martin Luther’s Protector (CPH):
