Tell them that you will be more than glad to discuss anything if they can answer 1 Thess 4:11-12
11 and to make it YOUR aim to live quietly and to mind YOUR own business and work with YOUR hands, just as we ordered YOU ; 12 so that YOU may be walking decently as regards people outside and not be needing anything.
Why are they here bothering you? Why did Paul say that we should all work with our own hands to provide for ourselves and family but they are taken care of by the Society off others contributions? Because, according to Paul, they are not walking decently in doing either one.
If they can answer both without Society literture, they are welcome to discuss anything on their minds.
