01The Toledan Anonymous

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. 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.

02Before Donin and Barcelona

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. 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.

Context

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.

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.
