I have a question that I would like to get input from you all on. I've been reading some of Richard Hays work on intertextuality and also am taking a course in biblical theology where this issue came up. When an New Testament writer alludes to or quotes the Old Testament, how often do they intend to pull in a wider context than the verses they just cited? To use a modern example, if you were delivering a speech on social justice, and you uttered the phrase, 'I have a dream' you probably would be doing more than just quoting a small phrase from Dr. King. You would probably be attempting to pull in the wider context of his speech and the moment in history and perhaps even of the character of Dr. King, himself. How often do biblical authors do the same thing and how integral is it to their arguments?
I am incluned to think that the above scenario does happen, so my follow up questions are, how conjectural should our exegesis be and what role this conjectural exegesis should have in the formation of our theology?
