Hershel Shanks’ editorship of another collection50 was considered only partially successful by the reviewer Martin Goodman.51 One of its strengths lies in the detailed histories presented by such authors as Geza Vermes, James Charlesworth, and Harold Attridge. Four writers in the same volume, Louis Feldman, Lee Levine, Shaye Cohen, and Isaiah Gafni, treat the history of the Jews. That same year, Princeton University Press published Feldman's treatment of significant questions relevant to the separation of Christianity from Judaism such as proselytism.52

As the source material for the early stages of the separation leaves many questions unanswered, it is possible for commentators to come to opposite conclusions when using the same source material. One example has been included in the chapter on Sabbath and Sunday.
