I currently have a Verbum package and I love it. I am currently working through the NT using TDNT. Having spent several years in academia I always do my best to check my sources and to learn about the authors and editors of works I am utilizing. While looking into the background of the editor of the TDNT, I discovered that G. Kittel seems to have been an Anti-Semite in the Nazi Party, advocated for the extermination of the Jews, wrote several academic papers on the "Final Solution", and was held by the International War Crimes Tribunal in Nuremberg, and Wlliam F. Albright is quoted in Wikipedia as stating to the Tribunal "In view of the terrible viciousness of his attacks on Judaism and the Jews, which continues at least until 1943, Gerhard Kittel must bear the guilt of having contributed more, perhaps, than any other Christian theologian to the mass murder of Jews by Nazis."
I also found this comment on a website, Biblical Research, http://biot500.wordpress.com/lessons/lesson-4-the-historical-study-of-the-bible/732-2/ : "Here’s an irony of history: This approach to getting at the Hebrew concept behind Greek words is best exemplified in Gerhard Kittel’s Theological Dictionary of the New Testament. Sadly, we have to acknowledge that Kittel was a Nazi, and there are anti-Jewish elements in his great work (he was the editor, other scholars wrote the individual articles). His teacher was Adolph Schlatter, a devout Christian with a love for the Old Testament and an appreciation for Israel’s testimony to Jesus Christ in the Old Testament. Schlatter developed the word study method in conjunction with his colleague Cremer and exemplified it in his 500 page study of Faith in the New Testament. The method, which Schlatter taught to his student Kittel was to study the usage of each NT word exhaustively including its use in the NT, in the papyri and Greek inscriptions, in classical Greek, and in the Septuagint—then to study the Hebrew word underlying the Septuagint concept. Each usage was studied in context, then various uses were categories, and the underlying theological concepts were clarified.
So, it wasn’t actually Albright’s students who produced Kittel’s TDNT, but it illustrates their way of doing theology."
While this does not, in itself, eliminate the TDNT as a good resource, I am cautious about what kind of influence this may have had on this work. I would appreciate some thoughts on this and on the reputation of the TDNT.
