Christian polemics and apologetics in the Middle Ages

The Crusades also formed the background to medieval Christian criticism of Islam and medieval Islamic criticism of Christianity, resulting in conflicting responses from Christian authors of chivalrous epics and hostile theological polemics.^[1][2] Peter the Venerable's commission of a Latin translation of the Qur'an, was followed by polemical writings from Pedro Pascual, Riccoldo da Monte di Croce Contra legem Sarracenorum "Against the Quran of the Saracens" (1300), and Ramon Llull.^[3][4][5]

Virulent antisemitism in medieval Europe obviated the need for any debate or discussion in most periods and most countries. However, during the 12th Century converted Jews such as Petrus Alfonsi and Pablo Christiani, well versed in Jewish religion, initiated the Contra Iudaeos (or Adversus Iudaeos) literature either from missionary or polemic reasons. This was both an impetus to and response to Jewish apologetics answering Christians, and more robust polemical writings (where safe to publish) among the community as a guard against conversion.^[6]
