James S. Bielo analyzes a practice of religious replication: re-creations of Holy Land sites in the United States. Such replications invite visitors into an experience of sensorial and imaginative immersion, marshaling indexical techniques for materializing the Bible. Replicating the Holy Land is a strategy for actualizing the virtual problem of authenticity, a problem that animates any and every lived expression of Christianity. To explore this phenomenon, we indulge another national tradition: the great American road trip. This essay emerges from a larger project, Materializing the Bible, curated by Bielo.
