I have to admit, I have no response to Dimond's quotes of St. Bellarmine regarding heretics loosing their offices prior the formal process. The biggest homework and value in that 2h discussion for me personally.
I hated Dimond interrogation style though. For the debate itself, it really does not matter what Cassman believes or not. Reasoning itself matters, this is what I learn the most (as opposed to mere knowledge of facts and quotes), and Dimond's reasoning seems to be very primitive.
Again, it is quite obvious that Cassman totally accepts the hermeneutic of continuity. In fact, he said it expressis verbis several times during the show. This is not even FSSPX position. Once you are there, it is an end of any meaningful discussion about the Tradition. I cannot resist an impression that that was his job - in a way - to discredit the Society. A little conspiracy here. Or he is just not very smart men.
The most amusing figure was the host of this discussion. I do not know his guy, perhaps some kind of NO conservative, but his facial "I am not happy" expressions during the show and resorting to a cigar or whatever he smoked to lower stress levels were priceless.
