On page xxxi it says (emphasis mine)
The Christian Apostle Paul, himself a Jew by birth, proposed in his writings a new view of the Torah. Its innumerable commandments, he held, constitute an overwhelming burden; no one can ever fulfill them properly. The “law” in fact, was given by God to make us conscious of our sinfulness, that we may despair of attaining salvation by our own strivings. Now, Paul taught, salvation is available through faith in the crucified and risen Jesus; the “law” has served its purpose and, for Christian believers, it is abrogated. This view has profoundly inflenced Christian thought, though the churches rarely adopted Paul’s teaching in its radical form and usually asserted the validity of the ethical laws of the Pentateuch.
In contrast, to and perhaps in reply to, the Pauline doctrine Jewish teachers insisted on the continuing authority of the Torah and on its beneficient character. “The Holy One, blessed be He, desired to confer merit on Israel; that is why he gave them a voluminous Torah and many commandments”. Failure to obey the Torah fully does not result in damnation; rather it calls for repentance (return) and a fresh start.
