I can vouch for the part of only using scriptures that are in the WatchTower lesson. I conducted the WT for 10+ years. It's drummed into your head by the Circuit Overseer, no extra research, even if it is JW literature, and no extra scriptures. We were told that the slave knew all of the extra research that we want to bring out, and the FS decided to leave it out and so should we! "We don't know more than the slave, do we? So leave it on the cutting room floor," was the C.O.'s words.
Now comments are to be 30 seconds or less. On the WT dealing with child abuse, no personal experiences were to be given.
