While I was at Bethel I had heard of thes sauna discussions. I had an opportunity to chat with Fred Franz on a couple of occasions (non-sauna)and enjoyed the intelectual excahnge. One of the things we discussed was the generation understanding which led me to help write the 1995 Watchtower article about the change in belief about "this generation".
Fred had a bit of an ego but was a bible student. This current GB is all about Organizational structure but less about being students of the bible. Franz was really one of the last actual students of scripture within the GB
