Hi John
I'd love to help you in anyway I can   but I don't live in the USA. But yes it happens in Aust as well!
I've had some experiences with xain counselling. For example: I did a 3 mth contract working  with the Salvation Army Family Services on a group project for Adult Survivors of Sexual Abuse (in Aust) You may not know but the Salvo's are fundamentalists ( I didn't know at the time)   That was the one and only time I ever worked with christians -   It was shocking. I complained to other agencies.  In fact made no offer to look into it.
On another  unrelated occasion,   I  needed to find out some info and sought the 'advice' from christian leaders - all I got was crappy 'cult' talk - that any 'church' that was dodgy or abusive was naturally a 'cult' and they the 'good' christians had no jurisdiction over them.
I'm also aware that in some denominations - the 'paster' is the only person who apparently has the 'authority' to counsel people but you know the drill.
So anyway...I know a little bit of the abuses people suffer at the hands of christians - counsellors, pastors etc. Its an incredibly vulnerable position to put yourself in. There are no accountability checks or any of the 'normal' client care systems in place. Amazing betrayals!

I wish you all the luck in the world! Hope your project gets the attention it deserves! I believe ANY kind of christian based counselling is going to offer an unethical   biased at the very least and when they start talking 'hell' and devil possession its outrageous! Most christian counsellor are not sufficiently trained & receive in house christian training.
