I think the majority of JW's would know the language Jesus spoke and that the bible was written in, but the last names of Jesus and Paul? Wouldn't have a Danny. Unless it's a trick question and they had a system like the Russian patrynomic - so Jesus Josephus, for example?
Btw didn't know you where Plymouth Brethren!Very exotic!You must tell US more about it....similarities, differences that sort of thing.
Fully agree that these so called Bible teachers have very poor knowledge, but what can you expect when all their critical facillities are locked down...they are spoon fed only what they need to know to recruit more workers, no more no less.
