It's the same for "Free Christians" in general, that is ex-JWs now enjoying Christian freedom. There's unity via what the Bible calls the greatest bond "love" (Colossians 3:14) rather than forced uniformity of views on all Bible doctrinal matters. Or to translate that a bit, while most for example may believe in some going to heaven and others resurrected on Earth, no one can speak for everyone else's views on such things, and yet we still present a united group against Watchtower dictatorship by staying friends (having Love) anyway.
There's two Christians. One knows all the Bible answers but is unloving. The other is totally unsure of any answers but is loving. Which do you prefer? Which does God prefer??
You know the answer. Love is the Way. The movement is a "fellowship" rather than a new church. The WTS laughs thinking "a movement" can't do anything to its Tower. Wrong!
Bill has freedom to believe however he wishes. The important thing is not what he believe so much as what he has done and continues to do to help the children, and yes, also the adults, whether JWs, exJWs or of the public.
