Excerpt of Carl Trueman regarding Luther:
“The dark side of Luther is nowhere more evident than his later writings on the Jews. This is a difficult subject, not simply because of the venom with which he writes but also because of the problems of writing about such from a post-Holocaust perspective. Three books in particular should be consulted. The first is Oberman’s The Roots of Anti-Semitism in the Age of Renaissance and Reformation, a classic articulation of the Jewish issue as one of religion. Eric Gritsch’s Martin Luther’s Anti-Semitism: Against His Better Judgment is also worth reading, in part because Gritsch himself was a member of the Hitler Youth. Finally, the recent volume by Christopher J. Probst, Demonizing the Jews: Luther and the Protestant Church in Nazi Germany deserves the widest possible readership, both for its brilliant analysis of how Luther was used by Nazi propagandists, and for the judicious questions it raises about Oberman’s central thesis. Paul Althaus (whose work The Ethics of Martin Luther is still worth reading) does not emerge with any great honour, I am afraid.”
