I have read in the ENGLISH language converage that the German expert on Islam mentioned by the Pope during his Regensburg Address, Prof. Adel Theodor Khoury, distanced himself from the Pope’s remarks. However, if you read the story, he didn’t do that. Here is what he said to the "Reuters of Germany" the DPA:
«Ich hätte mir ein paar Worte der Differenzierung gewünscht. Zwei, drei Zeilen hätten viel bewirkt» … "I would have wished for a few words of differentiation. Two or three lines would have accomplished a great deal."
«Ein unkluges oder gar fahrlässiges Verhalten des Papstes kann ich nicht erkennen», … "I do not see any imprudent or reckless behavior on the Pope’s part."
So, the prof is saying that this might have been softened a bit had the Pope said a little bit more about that citation, but that he didn’t see any thing in the use of it, per se, as being thoughtless or negligent. The professor even made the remark in that article that he himself has had to say at times that once upon a time people spoke in way that didn’t reflect his own point of view.
