Ah, Bishop Robinson!
This Episcopalian does not agree with him. I think he is on the outer edges of theological and scriptural thinking. Frankly, however I am glad he is making these efforts. We need someone to stretch the limits of theological thinking, so we can more carefully understand what those limits are. I frankly wish, however, that he did so as a scholar or theologian, not as a bishop.
Bishop Robinson is using standard scriptural exegetical practice of contextualizing the scriptures. This is an important part of exegesis. Unfortunately, I think is overstating the context. Homosexual activity was a common practice in the Graeco-Roman world, and he is probably right about the idea that “sexual orientation” as a recent concept to our time, is not directly applicable to the time of Paul. It seems he is taking whatever “wiggle room” he can find.
But as well as he draws out his argument, I just can’t see any warrant in scripture for sanctioning homosexual union or activity, period. If Jesus or Paul had wanted to, they would certainly have said so overtly.
First he tries to show that St. Paul was not talking about committed homosexual relationships, so, in his argument, St. Paul is silent on the topic.
Next he argues that since there is silence, there is no prohibition.
Finally he argues that in the absence of a prohibition, homosexual activity is permitted.
