To justify the miscarriage of justice, Father Zhukhovski and his accomplices induced a converted Jew, by the name of Serafinovich, who posed as a former Rabbi of Brest, and had testified at the Sandomir trial against the Jews, to write a book, entitled "Exposure of the Jewish Ceremonies before God and the World" (1716). The book, a mixture of a lunatic's ravings and an adventurer's unrestrained mendacity, centers around the argument, that the Jews use Christian blood in the discharge of a large number of religious and everyday functions. The Jews are alleged to smear the door of a Christian with such blood, to predispose the latter in favor of the Jews. The same blood put in an egg is given to newly-married couples during the marriage ceremony; it is mixed in the _matza_ eaten on Passover. It is also used for soaking an incantation formula written by the rabbi, which is then placed under the threshold of a house, to secure success in business for the Jewish inmate. In a word, Christian blood is used by the Jews for every possible form of magic and witchcraft. To convict Serafinovich publicly of lying, the Jews challenged him to attend a disputation in Warsaw in the presence of bishops and rabbis. The disputation had been arranged to be held in the house of the widow of a high official, and both the Jewish and Christian participants had arrived, but Serafinovich failed to appear at the meeting, where his trickery and ignorance would have been exposed. The refusal of the informer to attend the disputation was attested in an official affidavit. This fact did not prevent an anti-Semitic monk of Lemberg, by the name of Pikolski, from republishing Serafinovich's book twice (1758 and 1760) and using it as a tool to conduct a most hideous agitation against the Jews. In the large Jewish community of Posen, the slanderous accusations against the Jews were the reflection of the inveterate hostility of the local Christian population. Towards the end of the seventeenth century the Carmelite order in Posen contrived a curious lawsuit against the Jews, alleging that following upon the desecration of the hosts in 1399[154] the Jews had, by way of penance for their sacrilege, obligated themselves to accompany the Christian processions. The Jews denied the allegation, and the case dragged on for a number of years in various courts of law, with the result that, in 1724, the Jews had to pledge themselves to furnish the Carmelites with two pails of oil annually to supply the lamp burning in front of the three hosts in the church.
