What's wrong with that? He basically just articulated what the vast majority of Trads believe. When he added the next sentence about making the unity "visible", that's what nearly every singe one of the Feeney-hating Trads hold (barring a small handful of exceptions), that we were invisibly united even if it's not visible, eh? Otherwise, non-Catholics cannot be saved. So they're somehow invisibly within the Church. Leo Prevost is therefore, according to them, mostly Sedevacantists, ironically ... repeating what they consider to be Trad doctrine, and if you don't believe this you're a "Feeneyite heretic". So all this proves is that Prevost is not a Feeneyite heretic.
