The Calvinists Strike Back: The Infidel Delusion
I should very quickly point out that, although the authors are all, I think Calvinists and Triabloggers, none of this is about what is at issue between Calvinists and their opponents. From what I have seen, it does make some strong points. See especially Manata's discussion of the Outsider Test. (I'm not going to vouch for the tone of this document, though).
