For those interested in the discussion, Jim Hamilton has a good post tracing his own discoveries in this area. I think Jim is right when he writes: "I have come to the conclusion that people who question the way that the apostles interpret the OT, for all their protestation about reading it 'on its own terms' and 'in its own context,' have actually failed to understand the OT itself!" Jim also hints that he'd like to write a book on this someday.
I don't have immediate plans to post again on this topic, but those interested in digging deeper might want to check out some of Jim's articles:
“The Messianic Music of the Song of Songs: A Non-Allegorical Interpretation”
“The Virgin Will Conceive: Typology in Isaiah and Fulfillment in Matthew”
“The Seed of the Woman and the Blessing of Abraham”
For what it's worth, here's an idea-challenge for some of you to consider: start a group blog solely devoted to the issue of the OT in the NT, with the goal of turning it into a book. It would take someone with the motivation and knowledge to facilitate it. It would be a good chance for younger scholars and old scholars to collaborate. And I think it would serve the church--if it's pitched at a level that has some accessibility. If someone can get it rolling, I'll plug it.
