A Jewish woman had an intimate relationship with a moslem man. What is her status? I do not wish to associate with her. A jewish female relative is marrying a goy. We are not attending and will not congratulate them. It is likely to cause a permanent break.It is Hillul Hashem. What is the halacha in both cases? Thank you.
You should be cordial and decent, but you certainly have the right to cut off ties with these people. To do so is not a chilul Hashem. However in our day and age most people do these things out of ignorance and being completely disconnected from Judaism. It remains a mitzva to be mekarev these people to their roots and religion as much as possible. If maintaining a relationship with them may have such an effect it would be worthwhile not to cut off ties with them.
