According to
Jewish law, a child born to a Jewish mother or an adult who has
converted to Judaism is considered a Jew; one does not have to reaffirm their Jewishness or practice any of the laws of the Torah to be Jewish. According to
Reform Judaism, a person is a Jew if they were born to either a Jewish mother or a
Jewish father. Also, Reform Judaismstresses the importance of being raised Jewish; if a child is born to Jewish parents and was not raised Jewish then the child is not considered Jewish. According to the
Orthodox movement, the father’s religion and whether the person practices is immaterial. No affirmation or upbringing is needed, as long as the mother was Jewish.
