4 statements

01Voluntary converts in Toledo

In seventh-century Visigothic Spain, Skarsaune distinguishes forced conversions (a temporary survival strategy) from permanent voluntary ones, which Jews themselves treated as apostasy. Under Bishop Aurasius of Toledo (603 to 615), Rabbi Isaac, Joseph, Naphtali and other prominent Jews converted; the synagogue head Levi Samuel reacted harshly, and Count Froga even carried out internal Jewish 'justice' against the converts.

02Julian, Jewish-believing primate

Julian of Toledo (c. 642 to 690), son of Jews and not a convert himself, became the most powerful primate of the Visigothic church. Skarsaune treats him as the most prominent named Jewish believer in that church: trained under Eugenius II, he marked Spain as an independent archbishop until March 690. 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.

Context

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.

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.
