Jewish polemics and apologetics in the Middle Ages were texts written to protect and dissuade Jewish communities from conversion to Christianity, or more rarely to Islam. The terms polemics (from "battles") and apologetics (from "defence") may be distinguishedRobert Chazan Fashioning Jewish identity in medieval western Christendom, page 7, 2004. "I have used the term “polemics” broadly, not distinguishing between defensive thrusts, sometimes identified as apologetic, and attacks on the opposing faith. With regard to the distinction between those works intended for insiders and those for outsiders, I also use the inclusive term polemics, although I sometimes tend to call the latter missionizing or proselytizing works." but may also be considered somewhat subjective.The Oxford Dictionary of the Jewish Religion Page 60 ed. Adele Berlin, Maxine Grossman - 2011 "Jewish apologetics is less “apologetic” than the term indicates. Occasionally, too, Jews have gone on the attack." A smaller number of proselytizing text also exists intended to convert Christians, or more rarely Muslims, to Judaism. However, the vast majority of Jewish polemical literature was written in response to Christian polemical writings and with a permanent reference to Christian arguments.Philippe Bobichon, "Littérature de controverse entre judaïsme et christianisme : Description du corpus et réflexions méthodologiques (IIe-XVIe siècle) (textes grecs, latins et hébreux)", Revue d’Histoire ecclésiastique 107/1, 2012, pp. 5-48. online article According to Philippe Bobichon: "it is the permanent rooting in the historical reality that characterizes anti-Christian Jewish literature and distinguishes it from most anti-Jewish Christian writings. In all cases, without exception, this type of Jewish texts refer to a menace for the permanence of Judaism whose reality cannot be doubted." See: Ph. Bobichon, A Bird's Eye View on the Jewish Anti-Christian Literature
Under the pre-Christian and Christianizing Roman Empire Defences of Judaism to Greek, Egyptian and Roman religionists are found in Philo's Apology on behalf of the Jews,The Encyclopedia of Judaism ed. Geoffrey Wigoder - 1989, p. 68, "Apologetics and Polemics ... when Jewish writers sought to defend Judaism against the criticisms of Hellenism and paganism. Two noted works were Philo's Apology on behalf of the Jews and Against Apion by the historian Josephus, who vindicated the Jewish " and Josephus' Against Apion as well as other Hellenistic Jewish authors.Josephus' Contra Apionem: studies in its character and context Page 143 Louis H.

"Introductory words on the nature of polemics and apologetics - Josephus, admittedly, was not the first of the Jewish apologetics" In the early centuries following the emergence of Christianity from Judaism, but before Emperor Constantine's legalization of Christianity, mutual Jewish-Christian debate, polemics and apologetics occurred as for example in the words of Rabbi TarfonEssential papers on Judaism and Christianity in conflict: from Late Antiquity to the Reformation ed.

Middle Ages The Middle Ages is generally counted as covering Europe from the 5th to 15th centuries.
Under Islam During the Middle Ages many polemical texts originated outside Catholic Europe in lands where Jews and Christians were on an even footing as subjects of Islam. Among the oldest anti-Christian texts with polemic intent is the Toledot Yeshu "Life of Jesus" (7th century), although this does not follow the reasoned format of argument found in a true polemic or apologetic work. The earliest true polemic is the Sefer Nestor Ha-Komer "The Book of Nestor the Priest" (c. 600 CE).Joel E. Rembaum, The Influence of "Sefer Nestor Hakomer" on Medieval Jewish Polemics, in: Proceedings of the American Academy for Jewish Research, Vol. 45, (1978) The book represents itself as the arguments for Judaism of a former Christian (possibly Nestorian) priest.Daniel J. Lasker, "Jewish-Christian Polemics at the Turning Point: Jewish Evidence from the Twelfth Century", in: The Harvard Theological Review, Vol. 89, No. 2 (Apr., 1996) The need for apologetics emerged as national boundaries were in flux.Cursing the Christians?: A History of the Birkat Haminim Page 66 Ruth Langer - 2011 "These commonalities extend as well to the rabbinic discussions about the prayer and to many elements of the Christian polemics and Jewish apologetics that emerge in the late medieval world, particularly as national boundaries become ..."
Saadia's Kitab al-Amanat wal-I'tikadat "Book of Belief and Opinions" (933) includes refutations of the Christian Trinity, and more restrainedly against Hiwi al-Balkhi's arguments against the Jewish scriptures.Daniel Frank The Jews of medieval Islam: community, society, and identity 1995 Institute of Jewish Studies (London, England) page 176 "... obvious reluctance to polemicize against other Islamic tenets while exercising no such restraint vis-a-vis Christianity, it would seem that the discussion of naskh should be seen in the context of Saadya's anti-Christian polemic." The Cairo Genizah fragments include polemics against Samaritans, Christianity, and Islam, as well as Jewish sects, from the early 10th century.Encyclopaedia Judaica Volume 3 Cecil Roth 1972 "Fragments from the Cairo Genizah attest to the polemics directed in this period against the Samaritans, Christianity, and Islam, as well as Jewish schismatic sects, apparently from the beginning of the tenth century" cites J. Mann, Genizah Fragments of the Palestinian Order of Service (HUCA, 1925). Both Jews and Christians under Islam were careful in criticism of, or proselytizing to, their host's religion, in response to Muslim proselytizing of Jews and Christians.Religious apologetics - philosophical argumentation Yossef Schwartz, Volkhard Krech 2004 Page 240 "At the same time, however, the Qur'an defined for the Muslim polemist the areas of polemical activity, which differed for Judaism and for Christianity. In general, the disagreement with Judaism was limited to the charge of altering the.. " Page 204: "Joseph van Ess has suggested Hiwi al-Balhi's Questions concerning the Bible as a source of inspiration for a Jewish polemicist.51 These Questions prove indeed that criticism of the scriptures was not foreign to the Medieval Jewish.." Judah Halevi's Arabic Kitab al Khazari "Book of the Khazars" (c 1120), subtitled "The book of refutation and proof on behalf of the despised religion," included apologetics to Islam alongside Christianity and Greek philosophy.The Oxford Dictionary of the Jewish Religion Page 60 Adele Berlin, Maxine Grossman - 2011 "Later Jewish apologetics reasserted Judaism against Greek philosophy, Christianity, Islam (*Yehuda ha-Levi's Kuzari dealt with all three), "Holy people of the world: a cross-cultural encyclopedia Volume 1 - Page 342 Phyllis G. Jestice - 2004 "The book's subtitle, Kitab al-Hujja wa-al-Dalil fi Nasr al-Din al-Dhalil (The book of refutation and proof on behalf of the despised religion), identifies it as a work of religious apologetics."
In Catholic Europe Jews in Europe began to write polemical works in the 12th century.Berger David Jewish-Christian Debate in the High Middle Ages Philadelphia: Jewish Publication Society of America, 1979 in Jewish history and Jewish memory: essays in honor of Yosef Hayim Yerushalmi 1998 Page 26 "By the twelfth century, when European Jews began to write polemical works, they had far more information, which made their task easier in some respects and more complex in others. The Milhamoth ha-Shem "Wars of the Name" of Jacob ben Reuben (12th century) is an apologetic text against conversion by Christians, notable in that it contains questions and answers based on selected Hebrew translations of the Latin Gospel of MatthewWilliam Horbury Hebrew study from Ezra to Ben-Yehuda 1999 128 and appears to have served as a precedent for the full Hebrew translation and interspersed commentary on Matthew found in Ibn Shaprut's Touchstone (c. 1385).J. Rosenthal (ed.), Jacob b. Reuben, Milhamoth ha-Shem (Jerusalem, 1963), pp. 141-52
Joseph Kimhi's Sefer ha-Berit "Book of the covenant" (c. 1150) follows Jacob ben Reuben's format of an apologetic response to Christian argument,Susan Janet Ridyard The medieval crusade 2004 Page 37 "Both Jacob ben Reuben's Milhamot ha-Shem and Joseph Kimhi's Sefer ha-Berit begin with the Christian spokesman adducing a series of arguments to show that reason dictates the truth of Christianity. Once again, the Jewish participants in these dialogues assume a largely defensive position, although the Jewish defense is portrayed as spirited and convincing.1." but does not only refute Christian challenges, Kimhi also identifies weaknesses of Christian belief.Chazan 2004 "While the obligation of the Jewish polemicist begins with rebutting Christian challenges, it does not end with such defensive maneuvers. The responsibility of medieval Jewish polemicists, as perceived by Joseph Kimhi, extends to identifying weaknesses in the opposing camp and bringing them forcefully to the attention of Jewish readers. This aggressive thrust of medieval Jewish polemics is well documented in Sefer ha-Berit, and we shall cite this first of "
