Jewish-Christianity is a contested category in current research. But for precisely this reason, it may offer a powerful lens through which to rethink the history of Jewish/Christian relations. Traditionally, Jewish-Christianity has been studied as part of the origins and early diversity of Christianity. Collecting revised versions of previously published articles together with new materials, Annette Yoshiko Reed reconsiders Jewish-Christianity in the context of Late Antiquity and in conversation with Jewish studies. She brings further attention to understudied texts and traditions from Late Antiquity that do not fit neatly into present day notions of Christianity as distinct from Judaism. In the process, she uses these materials to probe the power and limits of our modern assumptions about religion and identity.
