God wants loyalty he wants to be put before a father, mother and children.
The wrongdoer changed his relationship with Jehovah and the family. It is their fault that we no longer speak to them. So the fact that the society directs family members not to associate with them is irrelevant. The fact that the disfellowshipped one still has affection for family and is not shunning them is irrelevent.
If he had remained faithful he would have a relationship with his family. So his relationship with family is conditional on shared belief. There is no relationship seperate from the religion no unconditional love.
Respect the decision. Even when it hasd been arbitrary and unjust.
Wanting to associate with family is a motivating factor to reinstatement. So belief in god is not necessary to be reinstated.
Even young oners who are disfellowshipped have a weak relationship with Jehovah. What the heck, young ones who are not old enough to marry or vote are made responsible for their own shunning because their relationship was weak. If it was so weak why didn't the elders detect this and refuse permission for them to get baptised in the first place.
When reinstated how would you feel if they asked why weren't you loyal to Jehovah. So in this fictitious world the newly reinstated person chastises their parents for a lack of loyalty. What if they never choose to be reinstated?
If we have greater affection for family members than for Jesus we are not worthy of him. I would suggest that anyone who expects their followers to be cold and hard hearted is not worthy of worship.
I like the way this talk centres around loyalty to God and Jesus rather than loyalty to the GB. In any other setting it is loyalty to the GB that is most important but in order to hate family members you have to go straight to the top.
