I'm still thinking about Walter Kaiser's post at Koinonia and trying to understand what he means when he ends with:
If the "Dead Sea Scroll in Stone" exhibits any message similar to what the prophet Isaiah laid out in the Third Servant Song, we are in for some very interesting Jewish-Evangelical dialogues! Perhaps the Church can pick up where it broke off from the Synagogue in the second to fourth Christian centuries! This would be one giant step forward for all who take Scripture and history seriously.
What is he trying to say? He never really talks about the "Dead Sea Scroll in Stone", despite the title of the blog post, aside from using it to bring up the suffering messiah idea. It seems like he's implying that if it talks about a suffering messiah (like he believes Isa. 50 does), then Judaism needs to rethink its rejection of Jesus as the messiah. If that's what he's saying, it seems like a bold non sequitur to me. It might not be what he means. After re-reading this paragraph several times, it just keeps getting more unintelligible.
First, the suffering messiah idea in the "Vision of Gabriel" itself is a weak interpretation. Second, reading it into Isa. 50 just perpetuates the type of category-mixing that is all too common in Old Testament interpretation, especially in dealing with the issue of messianic expectation.
