JWs are required to get stuck at somewhere around stage 2 and 3, accepting 'us vs them' paradigms and avoiding paradox. Maturing beyond that is seen as 'falling away' or worse 'apostasy'. This is of course very common in many religious institutions, but there is, I believe, a more mature way to practice Christian faith, away from the dogmatism and dualism of JWism and similar churches towards contemplation and compassion.
