6) At one level you are arguing that if we pay attention to the broader OT contexts of the OT texts that are cited, paraphrased, alluded to or echoed, we will better understand what the Gospel writers are saying about Jesus and his ministry. That would seem to presuppose a very sophisticated audience that has ‘the requisite encyclopedia of reception’ (to use your phrase) for any or all of the canonical Gospels, or at least an audience with a few persons very knowledgeable of the OT who could explain it to others. How would you account for this if, for instance Mark is mainly writing to Gentiles (who need periodic explanations of Jewish customs), or say Luke is mainly writing to a particular Gentile, or John, who often has to explain Jewish customs and seems to be writing to Gentiles? Are they writing well over the heads of their majority audiences, or are their audiences considerably more sophisticated than most scholars think they are?
***Yes, I get this question a lot. I suspect the answer is threefold: (1) Yes, the Evangelists may be writing over the heads of (at least some of) their audience; (2) Yes, the dissemination of the Gospels may have presupposed the presence of preachers and teachers in the community who were able to help congregations understand more; (3) Yes, the audiences (at least some in the audience) may have been more sophisticated than we suppose. ….It ought to be noted that authors do not always write for the lowest common denominator. Authors who know Scripture in their bones will simply allude to Scripture without stopping to explain. And sometimes authors simply delight in intertextual echo, whether the audience will get it or not. Example: Tom Wright’s Paul and the Faithfulness of God is full of echoes of Shakespeare, Jane Austen, etc. I have tested some of these passages on audiences and confirmed that for the most part these readers have no clue about these echoes, but they still love the book and can understand what Tom is arguing with or without the echoes.
***Interesting suggestion. This would correspond to point 2 in my answer to the previous question.
