- Q. Can one invite a guest home, that one is not sure if he is truly Jewish, since his mother is very assimilated?
A. There are many cases of kiruv of assimilated people in which doubts of the true Halacha of Jewish identity are common.
In general, our Rabbis maintain the common proper idea is, that each case is different and there are no real strict rules to follow, yet common sense and correct dedicated consulting each separate case with the proper Rabbonim and experts is the best rule.
One must always remember that Kiruv is a most important and critically vital mitzva for saving many spiritual lives. Experience and reality will teach everyone involved in Kiruv that there are no invariable and exact rules, as many cases of true successful Kiruv for many future generations can testify.
