The above video says they follow the lineage of Bp. Williamson, who was not an FE.

What does Hebrews 8:1 have to do with FE, St. Crysostom 

You know, Matthew, I realized something today. Years ago, when I was watching this one offshoot Transformers computerized animated cartoon called Beast Wars, it, of course, shows that the characters are on a global earth in the paradigm of evolution with primitive man. In a few episodes though, they come across a floating island kept afloat by what they call energon in the show that now would remind one of a flat earth kind of place. Eventually, the floating island sadly gets destroyed. Perhaps it was symbolic of mocking and trying to hide the flat earth reality.

Later on, I would actually for fun, draw floating islands. I wasn't the best drawer. My sister is good at it. Perhaps I was instinctively beholding the flat earth reality unconsciously?
