Of course, the correct answer was Russelites, but you and I know the REAL answer was "Bible Students", but that wasn't an option.
I believe they called themselves Russellites either before they called themselves Bible Students, or maybe at the same time. When they started to splinter into sects after Russell died, one group continued to call themselves Russellites. But according to them, they were the REAL chosen ones!
But you will never find this information in the Proclaimers book! They would have to admit that they follow man.
