Scripture As the Written Word of God (Sailhamer)

I've been reading a book by John H. Sailhamer that discusses Old Testament theology: it seems to be one of the more thorough OT theology introductions. In any event, Sailhamer makes this point about calling written scripture, the Word of God:

We will argue that both Scripture itself and the classical formulations of the doctrine of Scripture in the church lay the stress on the written Word of God as the locus of special revelation. In 2 Timothy 3:16 Paul writes, “All scripture is inspired by God.” In calling Scripture “inspired,” Paul gives it the highest claim to authority. It is specifically “Scripture” that Paul points to as the locus of God’s revelation. We should add that it was the OT that Paul was primarily referring to in this passage as Scripture. Moreover, in 2 Peter 1:20-21, Peter says, “First of all you must understand this, that no prophecy of scripture is a matter of one’s own interpretation, because no prophecy ever came by the impulse of man, but men moved by the Holy Spirit spoke from God.” Passages such as these in the NT have been primarily responsible for the classical identification of Scripture (sacra scriptura) and God’s Word (verbum dei) in Protestant theology.¹⁴ Although such an understanding of the nature of Scripture cannot claim universal acceptance among modern theologians,¹⁵ it remains the hallmark of those theologians who call themselves evangelical.¹⁶
