The economy of the gospel involves revelation and redemption alike: (1) Jesus “exegetes” the Father; (2) the apostolic testimony, preserved by writing in Scripture, “exegetes” Jesus; (3) preachers and theologians exegete the Scriptures that bear witness to Christ. The purpose of all this exegesis, and hence of Scripture itself, is not to displace Christ but to serve as the means for offering appropriately “thick description” of him. The Bible is the means by which the apostolic memory of what God was doing in Christ is given specificity and substance. For, as Calvin rightly says, the only Christ we have is the Christ of Scriptures. Hence the ground of Scripture’s indispensable role in the economy of the gospel is ultimately christological. The Bible-not only the Gospels but all of Scripture-is the (divinely) authorized version of the gospel, the necessary framework for understanding what God was doing in Jesus Christ. Scripture is the voice of God that articulates the Word of God: Jesus Christ.
Interesting, but i don’t feel comfortable with the term “exegete” in reference to the Father or the Son since the word has to do with text as opposed to person.
