Konceptual99 you provided a clear reason where you feel the policies has problems. I agree having more of a single policy would be better in the long run.
I don't think its possible to to have a single cohesive policy in a religious setting. There's too many variables and too many different circumstances. In a setting such as a school or youth club it's a lot more straightforward, in a religious setting less so.
i think that's reflected throughout different religions; I'm not sure Catholics have an if A then B type procedure. I would imagine their procedure is to phone the Bishop. Which is much the same as what the elders are told to do.
