On Venus, Have We Got a Rabbi!

On Venus, Have We Got a Rabbi! is a 1974 science fiction novelette by William Tenn. At an Interstellar Neo-Zionist Congress convened on Venus, weird-looking aliens claim that they are Jews. This legal quagmire was ingeniously resolved by the Great Rabbi of Venus. The story satirizes the question "Who is a Jew?". It was first published in the anthology Wandering Stars: An Anthology of Jewish Fantasy and Science Fiction edited by Jack Dann.
