Barney, I’m a little puzzled by your identification of “dogma” with “presuppositional framework”. The Oxford Dictionary of English defines “dogma” as “a principle or set of principles laid down by an authority as incontrovertibly true”. You don’t lay down presuppositions—they are already there. Surely a religious text is interpreted on the basis of presuppositions, and then an authority derives dogmas from that reading, which it lays down as incontrovertibly true.
These dogmas then become the presuppositions for subsequent readings of the text within the tradition, but historically they remain interpretive outcomes rather than starting points. The aim of a historical hermeneutic would be to establish the presuppositions of the community that originally produced and read the text. Those presuppositions, I would have thought, are clearly different from the conclusions reached by later interpreters.
