BTW, chag sameach.
“Messianic Jews” are a cult of former Lubavitch Hasidim who believe that the late Rebbe is the Messiah.
The “Messianics” referenced in this article are Christian. They may be Jews by ethnic origin, who converted to Christianity.
If an ethnically Jewish person converts to Islam, can they also claim Israeli citizenship according to the “Law of Return”?
Israel has already accepted over a million non-Jewish Russians from the former Soviet Union, who are not Jews ethnically nor by conversion.
The Supreme Court of Israel also REJECTED poor Jews from India and Peru, because they are Orthodox converts.
