I know (and knew) several people who knew the Archbishop personally. They ALL attest that he was mentally sound and that he celebrated mass perfectly. Anything but sedevacantism, right Sean?
Damn right, QVD, anything but schismatic, heretical sedevacantism.
Now back to the topic:
I don't care if you know 30 people with letters from their mommies who say Thuc was steady as a rock.
When bishops and cardinals, sedes, and trad priests say he was off kilter, your buddies' opinions don't amount to a hill of beans.
And I might ask, "Where is your common sense?" The man flies off at the drop of the hat to go consecrate some strangers becaause some other stranger arrives to tell him the BVM sent him to fetch him to go do some consecrations!?!?
Sorry but if you can't see that is crazy, I don't think I can help you.
