This study combines rhetoric, ritual studies, and comparative scriptures studies to open new avenues for understanding both biblical texts and their cultural history as a scripture. Labelling commentary as ritual, specifically as a ritualized genre of text, leads to the observation that commentary not only contributes to the Bible’s status as a scripture, it depends on that status as well. Ritual theories provide explanations for the dynamic interaction of tradition and innovation in commentary writing. Analysis of commentary writing and reading as a form of ritualizing the semantic dimension of a scripture provides a step forward in understanding how religious and academic communities use scriptures both to conserve a tradition and to adapt it to new circumstances.
