Let's say that a person has a reason to think his mother might be Jewish (there is some evidence, but only a little), and it is likely that the person will never be able to know for sure. In such a case, does he sin if he is Jewish and does not keep Mitzvot?
Is there a precedent or a standard ruling as to what a person like this should do? Should he convert? Or do you say that maybe it does not matter because if a person is unaware they do not need to follow the law?
(I am not writing about myself even thought I was in such a situation, as I have already made a decision what to do next. It is because I am curious about my family members.)
The question is not about conversion, it is about being unsure about whether one is a Jew and living like a gentile and if that is wrong.
