Google translate renders it fairly coherent.
The essay is largely based upon a book authored by Pope Benedict XVI’s favorite rabbi and one of the world’s most respected authorities on Orthodox Judaism, Rabbi Jacob Neusner titled, Jews and Christians: the myth of a common tradition.
The lengthy introduction is in English at Google books here:
The thesis of the book is stated plainly at the outset in refreshingly direct and concise language:
The thesis of this book is that Judaism and Christianity do not form a common tradition, “the Judeo-Christian tradition.” They are not compatible … only now, for reasons of politics and sociology, have some representatives of Judaism maintained otherwise.
While I agree with the learned rabbi in his statement of fact that Judaism and Christianity are entirely incompatible, I must add proselytism to the ‘Noahide’ religion to his list of reasons that some representatives of Judaism would claim otherwise (even Maimoides suggested that Christianity and Islam could be viewed as directing ‘the Goyim’ towards the ‘Noahide laws’) and I observe this ‘Noahide’ proselytism beginning many centuries prior to the “only now” of 2001 (the date Neusner’s claim was published) that Neusner identified as the genesis of a claimed “Judeo-Christian tradition.” In Neusner’s book, Historical Synthesis, he references the 18th century Brit-ish Rabbi Jacob Emden and his thesis that the Gospels were written to teach the ‘Noahide Laws’ to ‘Gentiles.’ Perhaps it was for political or sociological reasons that Neusner overstated his case here. Perhaps it is for the same such reasons that he has more recently apparently softened the hard line evident in his 2001 thesis.
