The Disputation of Barcelona

1263 CE

Biblical Narrative

On the twentieth of July 1263, in the royal palace of Barcelona, in the presence of King James I of Aragon (Jaume el Conqueridor), his court, the bishops of Catalonia, and a large delegation of Dominican friars, the most distinguished rabbi of Spain rose to defend Judaism against the charge that the Talmud itself confessed Jesus to be the Messiah. He was Rabbi Moshe ben Nachman of Girona — Nachmanides, known by his Hebrew acronym as the Ramban (1194–1270) — physician, kabbalist, biblical commentator, and acknowledged spiritual leader of Catalan Jewry. His opponent was Friar Pablo Christiani, a Jew of Montpellier who had converted to Christianity and become a Dominican, and who had spent years scouring rabbinic literature for passages that could be turned against the faith of his birth.

The disputation lasted four sessions, spread over a week. The format had been imposed by the Dominicans: only Pablo would attack; Nachmanides would defend; the agreed weapons were the Hebrew Bible, the Talmud, and the midrashim. Pablo's strategy was novel and dangerous. Earlier Christian polemics against the Jews had argued from the Hebrew Scriptures alone; Pablo argued from the Talmud and Midrash, claiming that the rabbis themselves, in their sacred and authoritative texts, had testified that the Messiah had already come, that he had suffered, and that he was divine. The implication was devastating: Jews who refused to accept Christianity were not merely wrong but dishonest, denying the testimony of their own teachers.

Nachmanides answered with a method as bold as Pablo's was clever. He distinguished sharply between halakhah — the binding legal core of rabbinic literature — and aggadah, the homiletical and narrative material in which the cited passages mostly stood. Aggadot, he argued, were sermons; one was free to receive them or not. He demolished individual proof-texts by reading them in context and by adducing parallel passages that pointed in other directions. And he made — extraordinary for a Jew speaking in a Christian royal court — bold theological assertions of his own: that the Christian Messiah, dead at the hands of Rome, had not in fact done what Isaiah had promised the Messiah would do. The wolf had not laid down with the lamb. Swords were not yet ploughshares. The world was not yet redeemed.

King James, by all accounts including Nachmanides's own, conducted himself fairly. At the close of the proceedings he gave Nachmanides a gift of three hundred solidi and dismissed him with a remark that the Christian friars in their fury would not let pass: that he had never heard a wrongful cause so well defended. Some weeks later Nachmanides composed his Vikuah — his Hebrew account of the disputation — and sent a copy to the bishop of Girona who had requested it. When the Dominicans saw it, they accused him of blasphemy and the king, no longer free to protect him, ordered him into exile. In 1267 he sailed to the Land of Israel.

We possess two contemporary accounts of the disputation: a Hebrew narrative composed by Nachmanides himself within months of the event, and a Latin protocol prepared by the Dominicans for the king and the church authorities. They disagree, predictably, on who won. They also disagree more interestingly on what was said. The standard scholarly edition that establishes both texts and their relationship is Hyam Maccoby's Judaism on Trial: Jewish-Christian Disputations in the Middle Ages (1982), which prints English translations side by side. The most thorough recent monograph is Nina Caputo's Nahmanides in Medieval Catalonia: History, Community, Messianism (2007).

The Disputation of Barcelona was the second of the great medieval Jewish-Christian disputations, after the Disputation of Paris in 1240 (which had ended with the burning of the Talmud). It was followed by the Disputation of Tortosa in 1413–14, the longest and most systematic of the three. Robert Chazan's Daggers of Faith: Thirteenth-Century Christian Missionizing and Jewish Response (1989) traces how the Dominican strategy pioneered by Pablo Christiani — using rabbinic literature to attack Jewish belief — was developed by Raymond Martini in his Pugio Fidei (c. 1280) into a systematic missionary apparatus that shaped Christian-Jewish polemic for the next three centuries.

The friars and the Jews — Jeremy Cohen's 1982 book of that title — argued that the rise of the mendicant orders (Franciscans and Dominicans) marked a fundamental shift in medieval Christianity's posture toward Judaism. Earlier Christian thought, drawing on Augustine, had treated the Jews as living witnesses to the truth of Scripture, to be tolerated as such. The Dominicans, equipped with growing knowledge of Hebrew and rabbinic literature, increasingly treated the Jew as a deviant from a Judaism the Jew himself supposedly betrayed. Pablo Christiani's argument — 'Your own Talmud testifies' — is the inflection point.

Nachmanides's literary legacy from the period after Barcelona is immense. His commentary on the Pentateuch, completed in Acre and Jerusalem in his final years, weaves peshat, midrash, and Kabbalah into a single sustained reading; it became one of the four indispensable medieval Pentateuch commentaries (alongside Rashi, Ibn Ezra, and Sforno). His epistle to his son ('Iggeret ha-Ramban'), counseling humility in the practice of Torah, is among the most copied private letters in Jewish history; it is still recited in some communities every week.

We have heard much of the man Bonastruc da Porta, that he is wise and learned; but we never thought he could say what he has said before us.King James I of Aragon, addressing Nachmanides at the close of the disputation (Vikuah, §117)
