The Bible has precious little to say about shunning. Write a scripture on each finger and you'll still have one clean hand.
But the Watchtower has managed to read into it a myriad (are non-JW's allowed to say "myriad"?) of rules about who to shun, how much, under what circumstances, etc.
One that caught me sideways a day or so ago was the fact that a wife with a DF'd husband doesn't have to shun him. They aren't supposed to talk about "spiritual things", but there's no straight out shunning. This is also true of DF'd children still living in the home. But as soon as the kids move out, they are supposed to be shunned. Why the kids and not the hubby? There are plenty of husbands that don't live with their wives, perhaps due to work. They drive to their worksite, live there for a month, then come back for a few days. Or they're truckers. Whatever.
The point is that when your DF'd spouse doesn't live with you, you don't have to shun them. But if your DF'd children don't live with you, they are off-limits.
What scriptural "justification" (excuse) do they have for this contradictory stance?
