Bobby, there is a distinction between dialectical and dialogical theology. Your thesis seems somewhat confused in that regard.
Also, not sure how you can claim that theological exegesis should be the 'only' way Christian thinkers and readers engage scripture. This comes across as nonsense when we consider the ways in which Bultmann's theology grew out of his historical-critical methods and interaction with existentialism -- he did not do theological exegesis as such. More often than not theological exegesis looks like isogesis in that there is a reading of the creed back into the text in a rather unhelpful way.
In response to this "commenter's" first gripe on the distinction between dialectical and dialogical theology. The really strange (presumptuous) thing about this, is that this commenter has never read what Myk and I develop in regards to this thesis. Beyond that, this commenter simply makes an assertion, and then presumes that he has made some sort of substantial point by simply asserting something without explanation!
As far as Bultmann. At the end of the day, I don't really care whether or not Bultmann did theological exegesis or not; I am simply reporting what Rowe and Hays "argued" (V. asserted) in their essay.
As far as theological exegesis usually leading to isogesis; this is just a ridiculous assertion. This presupposes that an exegete can come to the text of scripture without informing theological suppositions. But the fact that a person (any person) comes to the text of scripture to interpret it, presupposes that said exegete has already committed themselves to a particular theological grid (whether it be 'Christian' or not is another story). Furthermore, the fact that orthodox Christians believe in the Trinity etc., commits the Christian exegete, at least, to a fundamental theological principle that will shape their interpretive endeavor both dialectically and dialogically!
