Some thoughts on narrative and didactic genres of scripture

In begining I will open with a quick look at intended meanimg
a. Goal – “Intended meaning" is that understanding of a text which the Author/authors meant his original reader to know. After this the interpreter attempts to form a doctrine, based on the meaning of the text. That implies knowledge of weather the literary forms of of the text is set in a narrative and didactic context. No doctrine can properly be exegeted unless the frame is set.
b. What is narrative and didactic? Two genres of literature found in scripture the more common terms are story (narrative) and Teaching(didactic). It is commonly held that Narrative inform and yet does not command a normative standard for the grounding of any major doctrinal premise. Only the didactic passages teach us the foundational truths of the faith leaving the story to illustrate the truth. Yet is it dangerous to make such a hard and fast distinction. This elevation of the didactic is not absolute, we can not say, “Doctrines or ethical principles can only be derived from didactic portions of Scripture and never narrative portions of Scripture.” This is just not true, as a Baptist if I were to hold that hermeneutical principle strictly then I would not be able to give biblical grounding to the doctrine of baptism by immersion. Since the doctrine is based on the Greek meaning of baptism and the use of narrative text. Thus the key to knowing when something is worthy of grounding the truth of it in narrative sections of the text is precedence. If it is consistently found in a text as a pattern that the author is constantly revisiting, then we can begin looking at the text in a normative way.
c. Also, Paul implies that he used the Old testament narrative for didactic instruction in 2 Tim 3:16-17 and Rom 15:4. First 2 Tim 3:16-17 “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work.” Also when we look at Romans 15:4, Paul writes, “For everything that was written in the past was written to teach us, so that through endurance and the encouragement of the Scriptures we might have hope.” Historical narrative does have didactic value. So the question is how do we legitimately get doctrine and practice from narrative?
d. I think the best way is very simple. If you find in didactic portions of Scripture a minor truth then the use of narrative to flush out the simple understanding is expectable. When we say how does that look. Or what is the phenomenological understanding of that. Narrative is most helpful. Therefore the Didactic hold a first order in the text but not fully excluding the use or narrative as doctrinally defining.
