I just recently read this essay, and found it really interesting. I brought it up with some of the people n a group I attend at church, and they didn't seem to see much point in it. Now this is funny, because they are all rather older than I am, and so remember when the essay was actually written, and the "new" theology was really new.
It doesn't seem to be a well known essay but it would be great if anyone wanted to discuss it.
