Who qualifies as a Jew?
share.google/aimode/RfA0ehz4…
Traditionally under Jewish law, a person qualifies as a Jew if their mother is Jewish or if they undergo a formal conversion to Judaism. Because the Jewish people are an ethnoreligious group, Jewish identity functions like a tribal citizenship. A person born Jewish remains a Jew under traditional law regardless of their personal religious beliefs or actions. [1, 2, 3, 4]
However, exact qualifications differ depending on the religious movement and civil context: [5]
Religious Movement Definitions

Orthodox and Conservative Judaism: These branches strictly adhere to traditional Halakha (Jewish law). They only recognize individuals born to a Jewish mother or those who convert through an accepted Rabbinic court (Beit Din).
Reform and Reconstructionist Judaism: These liberal branches recognize patrilineal descent. A person qualifies as a Jew if either parent is Jewish, provided the child was raised with a Jewish identity and underwent formal Jewish life milestones.
Karaite Judaism: This distinct, non-rabbinic movement determines Jewish identity strictly through paternal lineage, requiring a Jewish father. [1, 2, 4, 5, 6, 7]

The Conversion Process
Anyone can theoretically become a Jew, though Judaism does not actively proselytize or seek out converts. A formal conversion typically requires extensive study, immersing in a ritual bath (Mikveh), and circumcision for men. Orthodox authorities generally do not recognize conversions performed by Reform or Conservative rabbis. [2, 5, 8, 9]
Civil Definition: Israel’s Law of Return
For secular, legal, and immigration purposes, the State of Israel uses a broader framework. Under the Israeli Law of Return, any person qualifies to immigrate to Israel and gain automatic citizenship if they have at least one Jewish grandparent, are married to a Jew, or have converted through an recognized Jewish community (including Reform and Conservative movements). [10, 11, 12]
