Earlier, you had stated the existence of several antitheses (plural) in the scriptures. Have you noticed however, that Synthesis is strikingly absent from the pages of scripture?
What fellowship has light with Darkness. It seems that Special Revelation (Scripture) is calling upon the man to choose sides, and not attempt to synthesise.
"Either make the tree Good and his fruit good, or make the tree bad and his fruit bad" (please forgive me if i do not quote accurately)
Excellent point, and it goes to show how easily we fall into a dualist mentality. In fact, what the authors suggests, which I did not include when editing this part of his book, is a three factor alternative. The author gives an example of a Christian view of government.
Christian view of Civil Government On a two-factor theology, once again, the norm for political life must be located either "upstairs" or "downstairs." If one opts for the former, the same familar problem recurs. Existing governmental establishments can then be defended with an appeal to divine will. The status quo gets canonized, allowing for no meaningful address to an accessible norm in support of a call for political reforms. The spector then arises of rulers shielding themselves from public accountability by an appeal to "the divine right of kings." This approach offers an all-too-easy answer to the question of civil disobedience- it is always wrong.
If, however, we choose to sit on the other horn of this sacred/secular dilemma, then the norm for goverment gets leveled out to the idea of popular soveriegnty. The vox populi then becomes the vox Dei. The basis for political life is then located in the will of the people, taking shape in a social contract, with public policy determined by majoritarian rule. Political practive can then rise no higher than a patriotic salute to "government of the people, by the people, and for the people."
Here, too, a three-factor view of reality offers an alternative. The norm lies neither in the hidden recesses of an inscrutable divine will nor in the arbitrary judgment that "the people have spoken," but in the mediating Word of God for public justice, given with creation, reaffirmed in the redeeming work of Christ, and illumined by the witness of the Scriptures. This view holds revelation and response together, each retaining its identity, yet always in a religously charged relationship.
So, I agree, synthesis implies dualism, when in fact we should thinking in the three factor alternative of good and evil and the mediating Word of God which gives direction to the good.
