I seized on this book when it had a review in Our Sunday Visitor newspaper. That was a couple years ago and I've forgotten the details of what is in the essays, but overall it is worthwhile.
I like the independent assessment of the statements in the NT.
One of the astute observations in there is that Paul did not suggest that Jewish Christians had to drop their Jewish customs, although he elsewhere says that the Gentile converts should not fall prey to the Judaizers, committing them to the precepts of the Law.
This general concept is expanded in Scott Hahn's Letter and Spirit, Vol 7. (there is no index in these publications, for some reason [probably cost]).
The OTHER inexpensive source of Jewish perspectives at a reasonable price is the Jewish Study Bible, from Oxford U. Press.
