In case anyone is interested, some of the information about Martin Luther's famous and not so famous views on the Epistle of James that is found in my James Through the Centuries commentary is publicly available, either here (at academia.edu) or here (Wiley-Blackwell; click on the "Read and excerpt" link just under the photo of the book cover). Since Wiley-Blackwell has made Chapter 1 publicly available, I also placed it on academia.edu (although the start of the discussion is found in the Introduction, which is not available online for free).
At this stage for the book on the reception history of the parables, I have written sections on both Martin Luther and John Calvin for Chapter 3. That may change, because I am already over the word count for Chapter 3 and have only written about six people (I need to limit the chapter to about 20,000 words and have written 26,000 already). The Luther, Calvin, Shakespeare, and (especially) Bunyan sections are way too long. The sections on Rembrandt and Anna Jansz are about the right length.
I have included both Luther and Calvin in the book, because Luther is a better representative (it seems to me) of the strong move against allegorical interpretations of the parables—although he does interpret some allegorically to a certain extent—and Calvin better represents detailed expositions of the parables in a non-allegorical sense.
