This sort of thing brings to mind Tom Wolfe’s hilarious novel “Man in Full”. A very unchurched young man ends up in prison. He requested a book of some mindless sort, but was, by mistake, given the writings of an ancient Greek philosopher. In that book, the philosopher talks a lot about Zeus. The young man becomes a devotee of Zeus because of the book.
Ultimately, he’s released, and meets an equally unchurched former real estate magnate and salesman extraordinaire and converts the latter to the worship of Zeus. Being a promoter by nature, the former real estate magnate starts a TV evangelism program for Zeus (much like the evangelical shows on there now) and attracts thousands of followers.
The whole thing is hilarious, but as with everything Wolfe writes, there’s a razor edge to it; his point being how unchurched and ignorant people are, and how gullible they are in the hands of a talented promoter.
So Thor? No surprise at all.
