It is the organization so it must be under the rule of governing body and that governing body should explain the Bible the way it will uphold the existence of the organization. Matthew 24.45-46 proves that there must be some over other who give spiritual food to those who are under the rule of that faithful servant.
Luke 9.49-50 allows for exception one may be a servant of God without belonging to any local church organization that is biblical but that servant cannot be against the true religious group.
I am not against Jehovah's Witnesses while being an indpendent christian for some 36 years .This can be done by you as well .
I don't have exactly the same interpretaion of the Bible like Jehovah's Witnesses share but recognize them as the only true christian church organization.
