Kevin DeYoung quotes Moises Silva:
In contrast , I want to argue not only that the exegete may address theological issues and suggest what bearing the text may have on theological reflection–I go a daring step further: my systematic theology should actually inform my exegesis. To put it in the most shocking way possible, my theological system should tell me how to exegete. (Interpreting Galatians, 207)
They fall back on, only when it suites them, postmodernism:
“Third, and finally, my proposal will sound a lot less shocking once we remember that, as a matter of fact, everyone does it anyway” (209). If postmodernism has taught us anything it is that none of us comes to a text with a completely unbiased, blank slate.
I disagree. I do think you can approach exegesis without bias.
If you approach exegesis only to support your theology, this is the basis of presuppositionalism, and in my opinion shows a lack of faith.
