That is the name ascribed by Jason Kettinger to the problems for Protestantism presented in my article The Accidental Catholic at Called to Communion. You can find a direct link to the article here. Since I am drawing attention to the article again, and since others have made the mistake of supposing it relies upon Catholic presuppositions, I suppose that I should point out once again that I was a convinced Protestant at the time that I realized the problems I present in the article, and that I had absolutely no interest whatsoever in investigating the Catholic Church. The point is that the problems I identify are intrinsic to Protestantism and do not rely upon an external point of view.
Thanks to Jason for the cool name, even though I have since learned that St.Francis de Sales made essentially the same argument a long time ago. :-)
