In the scholastic system of education of the Middle Ages, disputations (in Latin: disputationes, singular: disputatio) offered a formalized method of debate designed to uncover and establish truths in theology and in sciences. Fixed rules governed the process: they demanded dependence on traditional written authorities and the thorough understanding of each argument on each side.
A significant category of disputations took place between Christian and Jewish theologians as a form of both theological and philosophical debate and proselytization. Often, the Christian side was represented by a recent convert from Judaism. The only way for the Jewish side to 'win' was to force a draw by drawing the Christian side into a position in which it was necessary to deny the Old Testament to win, committing heresy. According to Michael J. Cook, "Since 'winning' a debate could well jeopardize the security of the Jewish community at large, political considerations certainly entered into what Jewish disputants publicly said or refrained from saying. ... Official transcripts of these proceedings, moreover, may not duplicate what actually transpired; in some places what they record was not the live action, as it were, but Christian polemical revision composed after the fact."
Martin Luther opened the Protestant Reformation by demanding a disputation upon his 95 theses, 31 October 1517. Although presented as a call to an ordinary scholastic dispute, the oral debate never occurred.
During a convention held at Heidelberg in April, 1518, Luther directed a dispute on 28 theological and 12 philosophical theses. He was successful in winning over Johannes Brenz and the Dominican Martin Bucer.
