Let Scripture Interpret Scripture

In our recent podcast on Genesis and Matthew, we considered how various aspects of the ancient Near East inform our understanding of Genesis. Indeed, there are many reasons to compare the Old Testament to the ancient Near East (and the New Testament to Second Temple Judaism). In both testaments, the historical background give us insight into the Scriptures. That said, there is more insight that comes from comparing Scripture to Scripture, by reading the Old Testament with the light of the new, by reading the New Testament with the background of the Old Testament, and reading both testaments as mutually-interpreting books of God's inspired word. In fact, on that very point New Testament scholar Grant Macaskill makes this wise observation:

New Testament scholars are usually very good at examining the context and backgrounds provided by Graeco-Roman and Jewish literature, but we are generally less successful at examining that provided by other New Testament writings and bringing these to bear on our exegesis. There is a vast amount of literature that reads Paul in the light of Qumran; there is rather less that reads Paul in the light of Peter.

The objection, of course, is that we run the risk of conflating the distinctive theology of each and doing so without sensitivity to the timelines on which they are located. But these texts are the products of a movement with a certain cohesion, generated within a compact period of time. It is, then, necessary to the historical task for us to consider how they may relate to one another and to reflect upon the ways in which even their diversity may emerge from a basic unity of thought. (Grant Macaskill, Union with Christ in the New Testament, 2)

I am not a New Testament scholar, but I believe his point applies to us all. The best interpreter of Scripture is Scripture, and so we should give equal---even greater!---attention to the rest of the Bible when interpreting Scripture. Sure, let's read extra-biblical texts that inform Scripture, but even more lets immerse ourselves in the Bible, so that our interpretations are saturated with the Bible and not just the latest academic fad or archaeological discovery.
