Here is the situation. I have 2 friends. A man and a woman and they are in a relationship with each other. They live together but are not married and have 2 young kids together. Neither are practicing Catholics. They just found a new apartment together. I am hoping they do not ask me to help them move because I am not quite sure that if I did, I would be sinning myself considering I know it is a sin to cohabitate. I have already been asked to help them with the move in a minor way but I said I did not think I could. They will most likely ask me to help with the move itself. I don't know if either of them even know it is a sin to live that way without being married but at the same time, what person has not at least head that pre-marital relations is a sin? I think most people do, but just don't care.
I am not going to preach to them about how co-habitation is wrong and all that, I am more than sure no matter what I would say, in any way shape or form, would not change their minds about anything. I really want no part of it all because I think I could be sinning if I did help and I scrupulous enough as it is without having that on my mind. Also of-course, I don't want to offend God. Would it be right if I just told them "Sorry, cant help you" if they ask me to help but give no explanation why. Also, what if they move in by themselves but ask me if I can help with the big stuff only (I have a truck) after the fact that they have already moved in?
