The De Arcanis Catholicae Veritatis (Orthona Maris, 1518) by Pietro Galatino stands as one of the most influential yet controversial products of the intellectual movement known as Christian Kabbalah. From the time of its publication, the work was met with accusations of forgery and plagiarism. Nevertheless, the Franciscan's extensive compilation and organization of sources profoundly shaped the Christian understanding of Jewish history, literature, and exegetical tradition. Even when criticized, Renaissance and early modern scholars frequently relied upon it. Galatino's distinctive contribution to the debate lay in his methodological proposal: he sought not only to refute Jewish thought but also to establish criteria for discerning what elements of Jewish tradition could be appropriated for Christian theology and exegesis and what should instead be regarded as doctrinally dangerous. Such a concern was not unique to Galatino but was shared by other humanists, most notably Johannes Reuchlin. Yet the answers they formulated were far from identical, and the taxonomies through which Jewish history and literature were classified were still in the process of being constructed and negotiated. Through an analysis of Galatino's treatment of the biblical Tiqqunê ha-Sofrim ("corrections of the scribes") in Book I of the De Arcanis, and by comparing his interpretation with both his medieval sources and his contemporary interlocutors within Christian Kabbalah, this paper highlights the originality of his taxonomy. It examines his strong distinction between judaei antiquiores and judaei recentiores, as well as his simultaneous conceptual overlap between Talmudists and Kabbalists, as a framework for reconfiguring the Jewish contribution to the Christian biblical and exegetical paradigm.
