Introduction to Norstrilia (Garden City, NY: Doubleday, 1976), by Alan C. Elms:
In those final years, Linebarger's [Smith] previously unfocused religious feelings intensified. He had grown up nominally Methodist, but had felt little interest in the more spiritual aspects of religion until Genevieve's mother underwent a painful terminal illness. As Linebarger and his wife began to embrace Episcopalianism (a compromise between his Protestant and her Catholic upbringing), the evolving worlds of Norstrilia acquired distinct religious undertones and overtones as well. But although Linebrger welcomed the ceremonial and communal aspects of Episcopalianism, his personal beliefs about salvation and the afterlife remained ambiguously unorthodox--as does the religion of the E'telekeli and his underperson disciples.
