The crucial question is simply this: “Which interpretation is right?” The easiest response would be to immediately say that the right interpretation is that which is most loyal to the original author’s intention. I think that this answer is right on in many ways.
However, to be honest, we must admit that such an answer is still situated within a certain interpretative framework. Authorial intention has not always been the flag flown throughout the church’s interpretation of Scripture. Besides how accurate we think such a framework may be, we cannot pretend as though this framework did not come within an interpretative community in the same way that other frameworks have. Authorial intention and reader-response and speech-act theory and the medieval four-fold sense have something in common: they are all products of a certain epoch within church history. They have not always existed. They have come to be.
To simply revert to the author’s intent would create the contention that we are claiming our interpretative community to be superior to other interpretative communities. It is not merely about which interpretation is correct, but would be about which method of interpretation is better. The question, “Which interpretation is better?” could be restated as “Which interpretative community is better?”
Now we are at the real question: To unfalteringly close your eyes and white-knuckle authorial intention at this point is on the verge of interpretative pride. Are we willing to say that the way we read the Bible at this point in time is superior to how everyone else throughout the history of the Church has read the Bible? Perhaps? The Church is growing up into mature manhood (Eph. 4:12-15).
But what do we say? Our understanding of Scripture itself is very important. We do not refer to our interpretative community norm in order to validate an interpretation of the text. We must refer to something that transcends interpretative communities altogether. The right interpretation of Scripture is the interpretation that is most fitting to the dramatic reality of what God is doing in Jesus Christ, by the Spirit, within the history of His creation. The witness of this dramatic reality is the canon. Kevin Vanhoozer writes:
The canon is the abiding theological witness to God’s pattern of communicative action in Israel and in Jesus Christ. As theo-dramatic script, the canon is witness to what God has done. As covenant document, the canon is witness to the solemn agreement that binds God and God’s people together…
The canon, seen in light of its connection to the covenant, is much more than a theological slide rule or criterion for true propositions. It has a properly soteriological purpose as well. The notion of covenant document helps to put the canon into proper perspective, with regard to form and content alike. As to content, Scripture depicts the history of God’s covenantal relations to humanity, including those divine communicative acts—promises, warnings, commands, consolations—that witness to what God was doing in Christ. As to form, the canon is an authoritative and binding witness to the fact, and the terms, of covenant relationship. The canon is thus the instrument through which the Spirit of God ministers and administers the covenant today. The origin (and hence the authority) of the canonical Scriptures is thus far removed from that of human constitutions (Kevin J. Vanhoozer, Drama as Doctrine: A Canonical-Linguistic Approach to Christian Theology, [Louisville: Westminster John Knox, 2005], 138).
The canon is the ancient witness to what God has already accomplished and it is also the ongoing reminder of what He has yet to consummate. It is the covenant record of His past faithfulness and the unwavering promise of His faithfulness in that which is yet to come. What fits into this far exceeds the human conjectures of any interpretative community.
We must submit our (or any) interpretation of Scripture to the canon, that is, to the greater reality of what God is doing through Jesus Christ and by His Spirit.
Vanhoozer again:
Dramatic fittingness with what God has done in Christ is the supreme criterion for truth, goodness, and beauty alike…
Christo-dramatic fittingness means canonical fittingness. We must think through the canon in order rightly to think about Jesus Christ. The standard of fittingness is specification of this “whole and complete” action. Sounds doctrine is distinguished from the dross of mere opinion only because the former accords with the commissioned testimony of the biblical authors and the latter does not (Vanhoozer, Drama, 258).
