As a child,Foxman would hardly be blamed for apostasising. Although the vast majority of Jews remained loyal to their faith over a millenia of threats, torture, inquisition, auto da fe, pogroms, cultural censorship, economic repression, and material blandishments, there has indeed been a steady trickle of apostates to Christianity.
Notable apostates included Pablo Christiani, Petrus Alfonsi, Artephius, Nicholas Donin, Abner of Burgos, Petrus Schwarz, Joshua Lorki, Johann Pfefferkorn, the parents of Nostradamus, Abraham Benveniste, Pfaff Rapp, Jacob Frank, Domenico Gerosolimitano, Paul Levertoff, the daughters of Moses Mendelssohn, Felix Mendelssohn. Aloisius Wiener, Franz Wentzel, Moshe Schneerson (son of the first Lubavitcher Rebbe), Bonaventura Mayer, George Lazarus, Isaac D'Israeli (father of Benjamin D'Israeli), Michael Bernays, Heinrich Marx (father of Karl Marx), Hans Herzl (the son of Theodore Herzl), Franz Rosenzweig and the composer Gustav Mahler.
And in this century Heinrich Heine, Boris Pasternak (author of "Dr.Zhivago"), the parents of philosopher Karl Popper, the grandparents of 1964 US presidential candidate Barry Goldwater, Bernard Berenson (art historian), Marcel Dassault (French industrialist), the nun Edith Stein, Chief Rabbi of Rome Anton Zolli, Moshe Rosen (director of "Jews for Jesus" in the USA), Clifford Goldstein (leading Seventh Day Adventist), Reverend Robert Weissman (of the London "Christian Jew Foundation"), musician Bob Dylan (on and off!), British MPs Nigel Lawson, Robert Adley and Edwina Currie, Bishop Hugh Montefiore, singer Helen Shapiro, Israeli atom-spy Mordechai Vannunu, Jean-Marie Lustiger (Cardinal of Paris and possibly the next Pope), the father of former US Defence Secretary William Cohen, and James Rubin (former US State Department spokesman).
