What the Archbishop neglects is that people do the exegesis. Exegesis most often follows from what the people doing the exegeting believe, not the other way around... When people accept same-sex love as legitimate, exegesis will provide the biblical foundation for it.
What Christians who approve of same-sex love need most is not more and better exegesis but to find non-exegetical ways to change hearts and minds. When that happens, the foundational and sustaining exegesis will be forthcoming. Selah!
Hint: The best, but not unfailing, way to change minds is to demonstrate the deep and immense suffering caused by the church's traditional attitude.
(Kenneth Cauthen at LIBERAL TO LEFT MUSINGS)
COMMENT: This is a hypothesis that I have put forward at OCICBW... in the past. The Bible may teach us how to do theology but, even so, only if we accept its contextual nature. But it was never intended to be the last word on every religious and moral question. If that was its intention then somebody would have done a much better job of editing it.
