They are two bishops short of a Council; two sandwiches short of a picnic, two bricks short of a load…
There are more than a few screwballs out there. This is just one example. To get this far off the track, if one is not mentally unhinged, then it is hard to guess how they could be so thoroughly out of touch with reality. But they are clearly not part of the universal Church; for starters, they have denied the power of the Holy Spirit and the admonition of Christ that He would be with the Church always. I think the common term is apostasy.
