A Question of Method...
Just clear something up for me. This is a mediation on the painting? Or an exegesis of Isaiah? Or are you using the painting as an illustration of your exegetical points? (Not being critical, just wanting to understand.)
Let me respond briefly, and then invite reader comments:
Thanks for this question, PamBG! No, I have no idea whether the painter had in mind Isaiah or any of these particular theological reflections. Responding to the painting, the art brings up Isaiah's theology for me and seems to express it visually. I guess what I have written is my "viewer response" as a theological thinker. Do you think this mode of reflection is legitimate? I am trying to craft a way of studying an artwork such as this as an exercise that is both spiritual and disciplined. Comments on method are most welcome... ---Steve
