I would advise against allowing them the "foot in the door" to what could lead to a JC process. This is a man-made concept and as the ARC has shown up, it is riddled with flaws -
The primary goal of any True Shepherd would be to impart love - and we know that this is not about that !
Marvin Shilmer's blog pages has an excellent check-list of what to do in prepping for a JC but the points could be used even in such a "visitation" as you can at least pave the way for any further process that may occur - eg taping the events etc having a third party present [ you don't have to tell them that this will be the case] Don't give too much info. Don't play your whole hand !
