From Donin and Barcelona to Iberian coercion

Date

1236CE

1236–1497

After Julian, Alvarus, Petrus Alfonsi and the Toledo Anonymous, the thirteenth to sixteenth centuries bring the 'discovery' of the Talmud, convert polemicists (Donin; Pablo Cristiani) and, after 1391, masses of conversos. Thematic continuity on the strand, without lineage from Nazoraeans or Ebionites.

10 statements

01Talmud and Dominican mission

Skarsaune links the ecclesiastical 'discovery' of the Talmud in the thirteenth century (Paris, 1240s) to a new Dominican missionary strategy: proving Jesus's messiahship from rabbinic literature. That prepares the public debates (Barcelona 1263) in which converts such as Pablo Cristiani confront rabbis with the Talmud itself. In later medieval Europe some Jews who converted to Christianity became polemicists against Judaism. Nicholas Donin brought the pope, in 1236, thirty-five charges against the Talmud; the Paris trial (1242) ended with the public burning of manuscripts. Pritz cites Donin and, later, Pfefferkorn as examples of converts hostile to the tradition they left.

02Convert polemicists

In 1263 in Barcelona, King James I forced Nahmanides to debate Pablo Cristiani, a Jewish convert to Christianity. It was the best known of medieval Spain's staged debates: two accounts survive (a Christian Latin one and Nahmanides's Hebrew reply). In later medieval Europe some Jews who converted to Christianity became polemicists against Judaism. Nicholas Donin brought the pope, in 1236, thirty-five charges against the Talmud; the Paris trial (1242) ended with the public burning of manuscripts. Pritz cites Donin and, later, Pfefferkorn as examples of converts hostile to the tradition they left.

031391 and the conversos

In summer 1391 riots that began in Seville killed or drove to baptism tens of thousands of Jews across Iberia. The Tortosa disputation (1413 to 1414) further increased conversions and consolidated the social class of conversos, whose ambiguous identity (and the charge of 'Judaizing') would shape Spain and Portugal in the fifteenth and sixteenth centuries. These medieval and early modern converts and conversos are Jews (or descendants of Jews) linked to the Christian faith, in the ethnic sense of this strand. They do not, however, form a continuous 'Nazarene' church from antiquity: they are phenomena of mission, coercion, polemic and social pressure inside Latin Christendom, distinct from the patristic sects.

04Continuity?

Claiming unbroken communal continuity from ancient Nazarenes to contemporary Messianic Judaism is a fragile position. What historiography supports more securely is the recurrence, across centuries, of Jews who believed in Jesus, under different names and conditions. In ancient sources the usual division is ethnic: believers 'from the Jews' and 'from the Gentiles'. Over time 'Christian' came to sound, to many Jewish ears, like something Gentile and non-Jewish; for that reason many modern Jewish believers resent the label 'Jewish Christian'.

Context

08

In this strand, 'Jewish believers in Jesus' means people Jewish by birth or by conversion who, somehow, held Jesus to be their savior. The criterion is ethnicity, not a single package of theology or praxis. That includes both those who kept a Jewish way of life and those who assimilated into mixed communities with a Gentile majority.

09

Petrus Alfonsi (formerly Moses), a Jew of Arabic culture from al-Andalus, was baptized at Huesca in 1106. His Dialogue between the Jewish self 'Moses' and the Christian self 'Petrus' is, for Skarsaune, better informed about Jewish faith and praxis than earlier adversus iudaeos tradition; he also translated from Arabic into Latin and mediated among the three worlds of Iberian convivencia.

10

In the second half of the twelfth century an anonymous Jewish convert of Toledo wrote a defense of the Trinity, the Incarnation and the fulfilment of prophecy; the work survives only because a Muslim polemicist of Córdoba (al-Imam al-Qurtubi) refuted it. Skarsaune places him in the Toledan circle of translators and polemicists, after Petrus Alfonsi and before the thirteenth-century Dominican turn.

Does modern Messianic Judaism continue the ancient Jewish-believing sects?

  1. A

    Claimed communal continuity

    Some modern adherents

    Part of the modern movement claims continuity of community across the centuries in varied forms and places.

  2. B

    Recurrence without institutional lineage

    Pritz and this strand's critical historiography

    Unbroken continuity is hard to sustain. Julian of Toledo, Petrus Alfonsi, Donin, Levertoff and the Messianic renaming show Jews linked to faith in Jesus under different names and conditions, without an institutional lineage from Nazoraeans or Ebionites.

The source’s assessmentZakhorium places ancient sects, medieval converts and modern Messianic Judaism on the same thematic strand, but distinguishes periods and avoids merging fourth-century Nazarenes with Iberian conversos or with the 1970s movement.
