A discussion of how Israel's immigration law treats Jewish identity, framed as a hard line against Jewish converts to Christianity.

• Under Israel's Law of Return, anyone Jewish by blood can move to Israel and get citizenship.
• But Jews who say they believe in Jesus lose that right, even if they face persecution at home.
• A Jew who openly rejects Judaism or calls themselves an atheist still keeps the right to return.
• The cutoff is about joining another religion, and atheism is not counted as one.

Outlook: The policy is long-standing and unlikely to change soon, but it keeps fueling debate over who counts as Jewish.
