So ... I listened to that sermon, and I really have no idea what you're talking about. It was weak and soft, with some general explanation of the error of Modernism, with a passing mention or two of Bergoglio. He spoke of Benedict in a very positive light, and very softly discussed the errors that Bergoglio taught (mentioning even his name in passing), and then say about Prevost that they were hopeful, are now somewhat disappointed, and that Prevost is at a crossroads.
If YOU think this is some kind of hard-hitting sermon "against the Modernist Church", then you've been percolating like a frog in the waters of SSPX too long and have no clue. While this is undoubtedly the strongest you're going to get out of SSPX, it was weak and utterly pathetic, and for you to tout this as if this was SSPX on fire against the Modernists, that's a very poor reflection on where you've ended up.
