I could not concur with Mike more on his comments on Gal. 6:16. Especially the comment: "Thus using "Israel" in a non-ethnic sense is possible for Jewish authors." It seems almost absurd to think that Paul, having argued for the unity of Jew and Gentile would as a finishing blow undermine his entire argument but separating the two. G. K. Beale's article: Peace and Mercy Upon the God of Israel was very helpful in explaining much of the backdrop to Paul's argument. This does lead to the vexing question of what to do with Romans 11:25-26. I part ways with many of my friends when reading this section. Wright has hit the mark for me on the whole of Romans 9-11, as opposed to Dodd - who thought it was just a separate sermon added in for good measure!
