ABSTRACT
The author's work in the history of religions, with special emphasis upon formative Judaism, required that the author sets Judaic systems within the context of Jewish history over time - besides the Rabbinic one that has predominated. A Judaic system is a religious system - ethos, ethics, ethnos - that identifies the Hebrew Scriptures or 'Old Testament' as a principal component of its canon. For a religious system works out, in vast detail, a few simple ideas. In the principles of selection and exegesis - the making of connections and drawing of conclusions that, in the case of Judaism, embody the faith's applied logic and practical reason - God lives. Writings such as those in the Judaic canon of the dual Torah have been selected by the framers of a religious system and the community that embodies the system, and, read all together, are deemed to make a cogent and important statement of a system, a Judaism.
