“Each Jew has the duty to work to burn down and exterminate Christian churches. The saints must be insulted and the priests killed.” (Schulchan-aruch, Jore be’ah, Page 146, 14. Aboda zarah and Hilschoth.) The Shulchan Aruch, sometimes dubbed in English as the Code of Jewish Law, is the most widely consulted of the various legal codes in Judaism. It was authored in Safed by Joseph Karo in 1563 and published in Venice two years later. Together with its commentaries, it is the most widely accepted compilation of Jewish law ever written.
