How Many Jews Are Alive Today?

Jesus and Mary.

Henoch was a pre-Flood man, Elias was a Samarian, and they remain so until they return.

The other guys who worshipped in the Second Temple (or the first) have died and not yet resurrected. Jesus and Mary are the last Jews alive in the body, through Final Resurrection, and the guys who are called Jews these days are another religion.

In the Gospel of St. John, they are, or their precursors in the life of Jesus are, diplomatically called Jews.

In the Apocalypse, Christians who were Christians of Jewish origin, were told that (at least some of) those guys, in the eyes of the King of the Jews, are not Jews./HGL
