In this book, Christoph Ochs presents for the first time an extensive study of the use of the Gospel of Matthew in Jewish polemics. These often overlooked texts advance numerous exegetical arguments against Jesus' divinity, the incarnation, and the Trinity. Seven Jewish polemical key texts comprise the main sources for this inquiry: Qissat Mujadalat al-Usquf (c. 8/9th century) and Sefer Nestor ha-Komer (before 1170), Sefer Milhamot ha-Shem (c. 1170), Sefer Yosef ha-Meqanne (c. 13th century), Nizzahon Vetus (13-14th century), Even Bohan (late 14th century), Kelimmat ha-Goyim (c. 1397), and Hizzuq Emunah (c. 1594). Together with the relevant passages in the original Hebrew and in translation, each text is presented with a historical and exegetical introduction. Contemporary parallels are also discussed, but in less detail. The result is a compendium of arguments against the divinity of Jesus based on the Jewish interpretation of Matthew.
