That was pretty much my thought as well. Who gives a flying F*** about scriptural rights to remarry. A child has been abused and it was never reported???
There are more important issues here than whether or not your daughter can re-marry. I am relieved you spoke about counselling and sincerely hope that you can convince your daughter to get your grand daughter into therapy. If the elders and your daughter have not reported this to the police I do strongly urge you to do so yourself.
This is not just going to disappear due to the public reproof. Pedophiles are repeat offenders. Other children in the neighbourhood and congregation need to be protected against this sick bastard.
