Let us consider the actual, worldly Jew - not the Sabbath Jew, as Bauer does, but the everyday Jew. ... What is the worldly religion of the Jew? Huckstering. What is his worldly God? Money. Money is the jealous god of Israel, in face of which no other god may exist. Money degrades all the gods of man - and turns them into commodities. The bill of exchange is the real god of the Jew. His god is only an illusory bill of exchange. The chimerical nationality of the Jew is the nationality of the merchant, of the man of money in general.
