Honestly I think we're missing the mark here on the whole bread thing. Yes it is poor from the perspective of too much explanation but the connection that's being made most prominent in this JWB is far more interesting to me.
Note that it starts out talking about grieving the Holy Spirit. it zeros in on what ways one could do that. Notice the early stress on deceit. Then notice the brother they show talking during morning worship.
It is clear they are tying in or making a point of grieving the Holy Spirit with speech. Deceitful or harmful speech. Note the stress on "not having all the facts". The stress on pulling back to get perspective.
It is clear to me that many are speaking badly against the organization. There's been a large contingency now after seeing the ARC.
Really feels to me like they're putting the fear in folks that are speaking basically the truth but it looks disparaging on the organization. They're saying your asking for the second death.
Agree the bread illustration a bit drawn out but the point being driven home here? To me stop talking about what you've seen you don't have all the facts if you don't stop it's an E-Ticket (Disney reference ) to Gehenna.
