A theological system and structure form foundations of, and are realized in detail by, the Rabbinic Midrash. That system, comprised by active category formations, turns facts into knowledge and knowledge into propositions of a theological character. The structure embodies the paradigm that solves new problems. So, the Rabbinic Midrash exegesis pertaining to theological matters proves coherent. Rabbinic Midrash follows a cogent theological program and sets forth an orderly theological construction. This work defines the principal parts of the theological system that animated the Rabbinic sages encounter with Scripture as embodied in the Rabbinic Midrash; and shows how these parts form a theological system.
