There are a number of other books in the rabbinic corpus—for example, Sifrei to Deuteronomy, Sifrei to Numbers, Sifra to Leviticus, Pesikta de-Rav Kahana—but I limit myself in this article to those books which are most relevant to my thesis relating to the parallel development of Judaism and Christianity. Other books of the rabbinic corpus responded to other issues and agendas relating for the most part to concerns internal to Judaism.
