Samuel David Luzzatto's approach to biblical interpretation defies simple categorization as "strictly traditional," revealing instead a nuanced methodology that merged fundamentalist beliefs with critical scholarship. Through close textual analysis of Luzzatto's writings, particularly his discussions of scriptural emendation and prophetic authorship, a more complex picture emerges. While maintaining the inviolability of the Pentateuchal consonantal text, Luzzatto consistently emended biblical texts from the Prophets and Writings based on historical rather than dogmatic reasoning. His stance on Isaiah's authorship stemmed not from traditional authority but from his commitment to prophetic veracity and his belief in the possibility of foretelling distant future events. The investigation reveals Luzzatto's biblical approach as "scholarly, non-traditional fundamentalism" - fundamentalist in his belief in scriptural inerrancy, yet non-traditional in his willingness to challenge accepted views through rigorous historical and philological analysis. These findings reshape our understanding of nineteenth-century Jewish biblical scholarship and position Luzzatto within the broader tradition of classical Jewish biblical exegesis, suggesting his potential significance for contemporary Jewish biblical interpretation.
