Luther’s genius was to infuse his translation with the words he heard on the street in his bit of Saxony, in east-central Germany. He obsessively asked friends and fellow scholars which dialectal words would be most widely understood. The common touch was so successful that a Catholic opponent complained that “even tailors and shoemakers…read it with great eagerness.” It was the bestseller of the century and remains the most popular German translation. Rarely has a single man had such a mark on a language.
