Sadly, I don't think it is obviously and overtly any of the identified formal heresies -- mostly because there's been no way to declare definitive formal heresy since the church has been in a state of schism, and there was no Prosperity Gospel or anything like it in the 6th century. I mean, even the heretics back then weren't that absurd.

Still, I'm sure there's a way to make the case indirectly ...
