I would like to ask David how he can possibly believe that the doctrine of disfellowshipping and its consequence of shunning can be based on love? Have you taken the time to read the many heartbraking stories of how families have been torn apart because of this? Is it right to tell a mother that she can no longer see/associate with her daughter? Is it right that a daughter decides to no longer see her mother? Is it right for a father not to be invited to his daughters wedding? Is it right that a son decides not to attend his fathers funeral? And all of this because a person may decide that he/she can no longer agree with the societies teachings (not necessarily that a person is an unrepentant sinner!) Is it right that a teenager gets disfellowshipped and is driven to suicide through guilt and despair?
Is it right that a person who still lives by high moral principles, who still loves God/Christ and has faith in the Bible, to be treated as if they were dead...even by their own family? It is noteable that Jesus allocated much of his time to the outcasts of Jewish society, those that were shunned and viewed as nothing.
If you have ever shunned someone, did it feel natural to do that? The reason it did not feel natural is because it was going against the very feelings and image of God that you were made in.
