So now the elders know that your father has chosen to reject your help to your parent...so are these elders then going to pick up the slack and does your father know and expect that? Or are they going to back off and leave him in a Catch 22 situation? Does your father view these elders and apostate dangers since they are not obeying the GB/FDS?
Is there someone who can keep an eye on them for you and report back and you can help through them?
