Unfortunately I lack the free time necessary for reading that book -specially in german version, because being able to speak and read in german it would be a shame for me not to read such a book in its native language-, but with your comments I somehow confirm my impressions about Ratzinger's doctrines and views so far. IMO he believes in Jesus as a concept (Something that if didn't exist, would need to be invented) and not as a historic figure. In all the speeches from him I have heard and the documents from him I have read (Mainly short ones and newspaper articles - letters) I started long ago to believe that he in fact does not care too much if Jesus really was historically what he wants him to be.
This Pope remains me more than any other to Dostojewsky's tale (In the Karamazov brothers) about the Chief Inquisitor in Sevilla confronted to a resurected Jesus:hmm:
Sadly, I would need to read this book to make a fair judgement about that, and as already said, I can't. So take what I have said before as simple superficial impressions.
Thanks for the "Fassung" of the book Skybird
