Hi all! Just a quick update-- my lawyer is reviewing my letter and said he will get back to me early this week. I did add a reference to the Australian RC. Also, I incorporated some of Marvin Shilmer's language regarding social contact.
In the meantime I have made a few phone calls and used some reverse "theocratic warfare" to get the names and addresses of the current congregation secretaries involved. There is some justice in the universe. The congregation secretary in my former sister congregation is the elder that was like an older brother to my son who ultimately played a role in getting him DF'd.
