Jewish dietary laws derive their enduring power not from health benefits but from their role in sanctifying daily life and maintaining religious distinctiveness, according to Rabbi Samuel H. Dresner's groundbreaking theological treatise on kashrut. Through critical analysis of contemporary Jewish scholarship, this review examines Dresner's work alongside Rabbi Seymour Siegel's practical observance guide and S.D. Goitein's biblical studies. While Dresner successfully reframes kashrut within Judaism's broader mission of holiness, his argument suffers from polemical attacks on Christianity and apparent discomfort with meat consumption. Siegel's companion guide proves more effective, offering clear halakhic guidance and practical implementation strategies. Goitein's biblical scholarship introduces innovative methodological approaches that place Eretz Israel at the center of biblical narrative while synthesizing traditional rabbinic interpretation with modern literary analysis. Together, these works demonstrate the continued vitality of Jewish intellectual tradition as it engages with modern sensibilities, though challenges remain in addressing interfaith dialogue and contemporary theological questions. The analysis reveals how modern Jewish scholarship successfully bridges theoretical foundations with practical applications of Jewish law and scripture, even as some works struggle to fully reconcile traditional and contemporary perspectives.
