Love for the family? Come on. I'm not suggesting that her actions placed the health and welfare of the kid at risk, and I don't suggest that it isn't her right to decide who to have as her patients and who not. But let's not suggest that her motivation was anything but disgust for them and their lifestyle.
So now you say she is lying, as too much like liberals, you cannot conceive of a Christian struggling to deal with Biblical conviction that they should not foster an immoral arrangement or life, while Christian love also wants the best for the person?
I have faced that often. For instance my former landlady took up separation from he husband (a nice man) and living with another man. I told them it was wrong, but would try to help them in ways i hoped did not infer sanction of their relationship. One time they asked me to help them move a new mattress to their house. And i wrongly did, but then said i was not going to take it upstairs.
I have had people ask me to fix their computer, while the reason it was infested with viruses was because of the immoral sites they visited. I want to help them, but probably should not, unless perhaps at least they promise me to stop using the PC for that purpose.
