When I read the part of the RC findings commenting on the biblical basis for some of their beliefs I thought immediately "that is something the WTS will pick up on"
Since their policies are loosely based on the bible, I think the ARC was trying to show them (and the world) that there is a biblical basis for adjusting policy. If they solely focused on policy, the JW response would have been that they follow the bible, that their policies are bible based, and that freedom of religion allows them to establish policies as they see fit. Of course they can come back that their interpretation is correct. All religions would. The ARC has demonstrated that the WT is unwilling to change even when there is ambiguity.
