What's worse? Breaking confidentiality or endangering children? Because those ARE the choices.
Those are not the choices. Parents should not trust anyone to begin with.
What makes you think that church elders don't protect the flock without violating confideniality? Everyone has children that go to church. But no one is perfect and sometimes imperfect church elders screw up. Wake up call for parents. Do not trust anyone with your precious little ones. They depend on you for protection. Trust no one.
You think church leaders are stupid, they have kids of their own that go to church and so do the other parishioners and church members. Of course they have any person that poses a potential threat on their radar. But sometimes they just screw up.
