The second century is a crucial period for the formation of both Judaism and Christianity, but remains in important ways terra incognita. This volume brings together specialists in Jewish studies and Christian studies, two closely related disciplines that nonetheless continue to operate in relative isolation. Taking into consideration the full panoply of Jewish and Christian identities, the volume proposes fresh ways to map the interrelated histories of Jews and Christians. Contributions by leading scholars offer new insights into this period informed by a rich variety of perspectives, including theoretical, literary, thematic and material approaches.

This volume discusses crucial aspects of the period between the two revolts against Rome in Judaea that saw the rise of rabbinic Judaism and of the separation between Judaism and Christianity. Most contributors no longer support the ‘maximalist’ claim that around 100 CE, a powerful rabbinic regime was already in place. Rather, the evidence points to the appearance of the rabbinic movement as a group with a regional power base and with limited influence. The period is best seen as one of transition from the multiform Judaism revolving around the Second Temple in Jerusalem to a Judaism that was organized around synagogue, Tora, and sages and that parted ways with Christianity.

The present volume gathers up studies by Peter J. Tomson, written over thirty-odd years, that deal with ancient Jewish law and identity, the teachings of Jesus, the letters of Paul, and the historiiography of early Jews and Christians. Notable subject areas are Jewish purity laws, divorce law, and the use of the name 'Jews'. The author also examines Jesus' teachings as understood in their primary and secondary contexts, the various situations Paul's highly differentiated rhetoric may have addressed, and the causes contributing to the growing tension between Jews and Christians and the so-called parting of the ways.

The papers in this volume are organized around the ambition to reboot the writing of history about Jews and Christians in the first two centuries CE. Many are convinced of the need for a new perspective on this crucial period that saw both the birth of rabbinic Judaism and apostolic Christianity and their parting of ways. Yet the traditional paradigm of Judaism and Christianity as being two totally different systems of life and thought still predominates in thought, handbooks, and programs of research and teaching. As a result, the sources are still being read as reflecting two separate histories, one Jewish and the other Christian. The contributors to the present work were invited to attempt to approach the ancient Jewish and Christian sources as belonging to one single history, precisely in order to get a better view of the process that separated both communities. In doing so, it is necessary to pay constant attention to the common factor affecting both communities: the Roman Empire. Roman history and Roman archaeology should provide the basis on which to study and write the shared history of Jews and Christians and the process of their separation. A basic intuition is that the series of wars between Jews and Romans between 66 and 135 CE – a phenomenon unrivalled in antiquity – must have played a major role in this process. Thus the papers are arranged around three focal points: (1) the varieties of Jewish and Christian expression in late Second Temple times, (2) the socio-economic, military, and ideological processes during the period of the revolts, and (3) the post-revolt Jewish and Christian identities that emerged. As such, the volume is part of a larger project that is to result in a source book and a history of Jews and Christians in the first and second centuries.
