A portion of the outline to be considered with the the elders, looks like they just can't ignore the problem anymore:
Remain alert to dangerous and divisive influences [Read 1 Peter 5:2, ftn.]
Disruptive ones may threaten the life or safety of those at congregation meetings
Question: What can be done to render assistance to a publisher who is distressed after reading a negative report about God’s organization? [Help him to remain united with the congregation. Reason with him on appropriate Bible principles and published material (Pr 14:15; Isa 28:16; 2Th 2:2; g 12/13 5-7; w95 4/1 27-28)]
