Ok here is what I think: Jesus was very broad in making his statement to Nicodemus about being born-again. It simply includes being born of water (as in baptism) and spirit (aren't we told that all JWs have the holy spirit--as much as the anointed do?) And at baptismal talks, the candidates are told that from that day on, they are ordained ministers being ordained by God. Doesn't that include some holy spirit there?
OTOH, Paul, I believe is narrowing this down to a specific part of being born again, because his points were for those who had received a heavenly calling as adopted sons of God. That would be the anointed. Whatever I understand, from the Insight book, on this subject about the anointed having righteousness imputed to them, yadda, yadda, yadda, I hear the same thing from born-again Christians.
However, this one particular scripture really drives home the point for me and I feel the society should address it:
1 John 5:1 "Everyone believing that Jesus is the Christ has been born from God, and everyone who loves the one that caused to be born loves him who has been born from that one."
So by stating that only the anointed are born-again, the society is implying that the great crowd hate and disbelieve in Jesus and his Father. I don't like that implication and I think it needs to be addressed by them soon.
