I along with Matt do not recall this clear, forthright list of "errors" of the SSPX. Like I said, he just drops the line. I do recall challenging him in the past to put up or shut up, but his hit and run posts haven't cleared anything at all. So, I'd like to see a list of these alleged errors. Mike's a great social commentator, he's very good at analyzing human behavior, but he is theologically inept, he doesn't understand even basic theological concepts or principles and his scriptural exegesis is equally unsound. I suspect that's why I've never gotten more than two posts out of him when directly challenged on a theological topic.
SS, your example of an "error" is absolutely ridiculous. SVism is an opinion regarding a contingent fact; rejeccting this conclusion doesn't even come close to the censure of theological error. No one likes a dogmatic sedevacantist, even most sedevacantists don't like dogmatic sedevacantists so really, you should try to confine your list to offenses against Catholic doctrine, not mere opinions.
