John Webster on the theological interpretation of scripture
The task of biblical interpretation is a function of the nature of scripture; the nature of Scripture is a function of its appointment as herald of the self-communicative presence of the risen one. […]
Proposals about “theological interpretation” of the Bible commonly lack an ontology of scripture. Theological interpretation is often described as a distinct hermeneutical strategy or interest — a matter of reading for certain theological themes (rather than proceeding no further than historical or literary content), or, perhaps, a matter of reading under the tutelage of the church’s traditions of interpretation, or of reading virtuously. Much can be said in favor of these claims, but they will only prove fruitful if grounded in a theological account of what Scripture is. Questions about interpretive methods can only be settled “metaphysically,” that is, by working out what the text is, who we are as its interpreters and what ends we are to pursue as we read it. The core of such an account is, of course, the doctrine of the triune God, who alone is the ratio essendi et cognoscenti [the logos of being and knowing] of all creatures.
