Here is a nifty paradigm for understanding scripture that I picked up from Pratt. I go to RTS-O so obviously it is going to be Triperspectival.
Scripture = Painting- Window- Mirror
(I wanted these to form a triangle but WordPress hates me)
Normative: Scripture is a painting because it is a literary object of art that the Biblical authors/ Holy Spirit shaped and molded to present a message to their people. A.K.A. Literary Analysis
Situational: Scripture is a window in which we see God’s work and word in which he redeems the cosmos. A.K.A. Biblical Theology
Existential: It is a mirror because we subjectively see things in scripture that will uniquely stand out to us as individuals or communities. A.K.A. Systematic/Thematic Theology
All three of these perspectives on scripture are in a constant relationship with each other as we forge our theologies. In wisdom its best not emphasize one over the others but to understand how they work together. In fact it is impossible to do one theology without the other.
