I think Matthew was refering to cc23's membership, not his salvation. But with extreme views like that, I do worry about him.
He was a nice guy, but like I said, he should have made his retraction and then stopped. Instead he goes on to say that most Traditional priests are heretics and that people who accept BOD and/or aren't sede can't be saved, then says he will pray for our "conversion". Pure insanity. He may have retracted his pro-MHFM stance, but his views sure didn't change. Again, nice guy, but needs prayers.
