"Jewish-Christianity" is a contested category in current research. But for precisely this reason, it offers 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. In this book, 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 probes the power and limits of our modern assumptions about religion and identity.
