There are some religions in which converting new members is written into the doctrine. But Judaism is different. While we welcome new members of the faith with open arms, we do not seek out possible new converts.
In Israel, the Law of Return has been written into the cultural and legal system for 70+ years. But not everyone agrees with the specifics of the law. According to traditional Judaism, a Jewish person is defined by the faith of their mother. If the mother is Jewish, either by birth or conversation, the child is Jewish. But if the father is Jewish, but the mother is of another faith (or no faith), the child is not Jewish.
Earlier this month, the High Court finally recognized that Reform and Conservative conversions carry as much weight as Orthodox conversions. This hopefully also extends to the marriage ceremony. Civil marriages do not exist in Israel. The only marriages that are recognized are those performed by Orthodox rabbis. More than a few couples have left the country to get married.
This change is fifteen years in the making and frankly, should have happened a long time go. It shouldn’t matter how one converted. It should only matter that they are as committed to the Jewish faith as those who were born into it.
