Another interesting point I found is its not just letters but there is also verbal instruction as well as instruction given at elders school that has even less of a paper trail.
This point was brought out in the Richard Ashe deposition this is Zalkin reading from a paragraph in an outline for a elders school.
Q. In that it says, "When one fills his mind with the many wholesome, good, virtuousand loveable things of God's word, such a one is strengthened and refreshed," and it cites Psalms 19, 7, 8, and 14. "Experience proves that constant rehashing of past abuse has a discouraging effect. It is not wise for one to indiscriminately divulge ones past bad experiences to others in the congregation, nor to get together with others for what some view as group therapy. Talking indiscriminately to others about child abuse, may result in circulating damaging and harmful talk. Such talk may be slanderous if proof of alleged wrongdoing is lacking."
Interesting is the last point Slanderous comments is a disfellowshiping offence, so if a victim of abuse was to continually talk about the case with others in the congregation (non-elders that is talking to elders about anything even if there is little evidence is not slander, this would also include talking with authorities) they could face a judicial committee if they were "LACKING" in evidence of the wrongdoing.
