There is an account of that conference in a parchment MS., consisting of 409 fols., in Sto. Lorenzo del Escorial, entitled, "Hieronymi de Santa Fide Medici Benedicti XIII. Processus rerum et tractuum et Europæ, Rabbinorum ex une parte, et Catholicorum ex alia, ad convicendos Judæos de adventu Messiæ." Contemporary Jewish writers are ominously silent about it. The story of Joshua Halorki is full of suggestive matter for serious thought for the Rabbis of modern synagogues, and for Christian ministers of modern churches. John, of Valladolid, born 1335. An able speaker and acquainted with rabbinical literature, he persuaded King Henry of Castile that he could convince the Jews of the truth of Christianity if they were obliged to listen to him and to answer his questions. An order was accordingly issued, compelling the Jews to attend John's lectures in their synagogues and to discuss them with him. In company with another Jewish convert, John travelled throughout the Castilian provinces, lectured and debated in the synagogues, but with lack of success. At Avilla, he assembled the Jews four times and discussed with them the tenets of Christianity before numerous Christian and Moslem audiences. At Burgos, he summoned Moses ha Cohen, of Tordesillas, to a religious controversy in the presence of Archbishop Gomez, of Toledo, but he made no impression upon his opponent. Just because he was not content in bringing arguments from Scripture to prove Christian doctrines, but in imitation of the rabbinical method, he tried to base a doctrine on the form of a letter. Thus, for instance, he claimed that the final closed "mem" in the word [Hebrew: lemarbeh] (Isa. ix. 6), is an allusion to the immaculate conception. Levi Barach (Joseph Jean François Elie), born at Hagenau, Elssas, 1721, embraced Christianity in Paris, 1752. His wife refused to live with him, and he refused to divorce her according to Jewish law. He obtained from the Bishops of Verdun and Metz canonical opinions that a baptized Jew might marry a Christian if his wife refused to be converted with him. Levi Ben Shem Job, Portuguese convert, lived at the end of the fifteenth century. He is identified by some scholars with a certain Antonio, who was chief surgeon of King John II., and who wrote a pamphlet entitled, "Ajudo da Fé Contra os Judaeos." Mandl Christof, a Hungarian Jewish convert, baptized in 1534. His godfather was George, Margrave of Brandenburg, to whom Mandl dedicated his tract entitled, "Dass Jesus sey das Ewig Wort" (1536). He also wrote two other tracts on the "Seventy Weeks of Daniel," and "Jesus is the Messiah" (1552-7).
