My research and publications have two focuses. First, Jewish contexts of nascent Christianity. Here, I continue an already traditional direction of investigating patterns of Jewish thought from late Second Temple period as possible background for the beliefs of Jesus' followers. I am also interested, however, in a complementing track, namely, mapping early Christian traditions as potentially bearing witness to broader Jewish tendencies – tendencies, which otherwise are attested only in later rabbinic sources. Second, I study the strategies of early Aramaic-speaking (Syriac) Christianity, employed it its search for self-definition vis-à-vis, on the one hand, the dominant Greek Christianity and, on the other hand, Babylonian Jewry, to which it is close geographically and with which it shares the same language of religious discourse. In my research, I also enjoy the collaboration, and joined publications with colleagues outside the Department of Comparative Religion – both from the Hebrew U. and from other Israeli universities.
