The English translations of Alonso de Cartagena’s Defense of Christian Unity.


Alonso de Cartagena, bishop of Burgos in the Spanish kingdom of Castile, wrote the Defense of Christian Unity in 1449-50 in response to a violent uprising in Toledo that targeted conversos—baptized Jews and their descendants. While responding directly to adversaries’ claims about the perpetual, stiff-necked, deicidal animosity toward “Old” Christians that inevitably characterized conversos of Jewish lineage, Cartagena crafted one of the most articulate defenses of the conversos as legitimate Christians not in spite of but precisely because of their kinship with the Apostle Paul according to the flesh. The first-ever English translation of the Latin treatise appears in this volume, with a side-by-side Latin edition, along with the first English translation of the Castilian (Spanish) Appeal and Supplication of the Bachelor Marcos García de Mora, the spokesman of the conversos’ enemies, as an appendix. On the cusp of the era of European exploration and colonization, we hear Spanish Christian authors arguing about the nature of Israel and its relationship to the Church, the authority to read biblical and legal texts, the relationship between religious and national identity, the meaning of baptism, and the prospect that spiritual and cultural characteristics could be inherited in the body and affect civic and Christian status for generations. These texts allow readers to explore such urgent theological and political questions as they emerged out of the converso debate and reflect on how they appear in the present day, when we have yet to settle the relationship between the spirit and the flesh.
