My own proposal in Divine Discourse was that, instead of thinking of the Bible in terms of revelation, we think of it in terms of speech; second, instead of giving priority to speech as symbol-system, we give priority to speech as action, as discourse; third, that within discourse we distinguish between locutionary acts and illocutionary acts; and fourth, that we introduce the concept of double agency discourse; thereby enabling us to understand how it might be that God speaks- that is, performs illocutionary acts- by way of the writing and speaking of the biblical writers.
