Prayer books risk becoming spiritual fossils - repositories of mechanically recited words rather than vessels of living worship. Drawing from his experience editing the Rabbinical Assembly's High Holy Day Mahzor, Harlow explores how innovative design and careful translation can reanimate Jewish liturgical texts for contemporary congregants. The project employed strategic two-color printing (black and purple) to distinguish liturgical elements and enhance visual navigation, while modernizing archaic English translations without compromising theological accuracy. By integrating historical and contemporary sources, including newly discovered medieval liturgical poetry, the editorial process revealed an unexpected finding: ancient and medieval texts often resonated more powerfully than modern compositions. The methodology balanced aesthetic considerations, scholarly research, and practical worship needs, developing solutions like color-coded Sabbath passages and seamlessly integrated devotional commentary. Through collaborative relationships with modern composers and writers, the project achieved its core aim: preserving authentic Jewish liturgical tradition while making it accessible to modern worshippers, many of whom lack Hebrew fluency and struggle with traditional prayer forms. The findings offer broader insights into maintaining spiritual vitality within formalized religious practice.
