I've figured you out, Caminus, when you get caught in a logical contradiction, you resort to ad hominem attacks, laughing emoticons, etc.
You've skirted the issue that you deny the Church's disciplinary infallibility (talking around it with a litany of equivocations about positive, negative, yada yada), say that the Church can teach errors left and right, but then somehow imbue the Dialogues of St. Catherine with a kind of infallibility, attacking me for basically not treating every statement in there as an implicit act of the infallible magisterium.
