A sound expression of a covenantal-historical reading of Moses:
Classic covenantalism recognizes that the old Mosaic order (at its foundation level — that is, as a program of individual salvation in Christ) was in continuity with previous and subsequent administrations of the overarching covenant of grace. But it also sees and takes at face value the massive Biblical evidence for a peculiar discontinuity present in the old covenant in the form of a principle of meritorious works, operating not as a way of eternal salvation but as the principle governing Israel’s retention of its provisional, typological inheritance.
Classic covenantalism seeks to do full justice to this complexity by distinguishing two levels of the old covenant, as suggested above.
