Dear s2srea,
I've been to a few MJM conferences in the past, myself... earlier this year Mr Matt held a conference to "unite all of Tradition" against the apostasy of Rome and to address the crisis . I suspect that was the conference where you saw Bishop Schneider speaking. He was there.
Because it was advertised as bringing ALL of Tradition together ( representatives from the FSSP , SSPX as well as some "friends of Tradition" from the Consiliar church attended ), I wrote on the Remnant comment board that Mr Matt needed to include the four Resistance Bishops if he were serious about including everyone in Tradition.
Well ...fireworks was the response from Mr Matt. ( I strongly suspect he was the comments moderator by his personal reference to Bishop Williamson and sincerely nasty response to me- I don't think a hired moderator would be allowed to go there) Needless to say he didn't feel Bishops Williamson, Faure, Aquinas and Zendejas names should even be mentioned, let alone invited. We may be critical of MJM, but he doesn't even want to acknowledge our existence however valid it is.
