The 19th century German Jewish reformers' embrace of "temple" terminology reflected deep anxieties about acceptance in Christian society, marking a deliberate attempt to reframe Judaism as a familiar religious institution rather than a foreign cultural presence. Through comparative historical analysis spanning from the French Revolution to the post-Holocaust era, this research examines how institutional nomenclature intersected with architectural choices and liturgical practices to shape Jewish religious identity. The shift from "synagogue" to "temple" inadvertently replicated the hierarchical, passive worship structure of Solomon's ancient Temple, diverging sharply from the participatory nature of traditional synagogue worship. In today's context of religious freedom and cultural pluralism, American Jews no longer require such accommodations to Christian sensibilities. Conservative Judaism would better serve its constituency by embracing authentic synagogue practices characterized by participatory worship, egalitarian principles, and intellectual honesty in textual study, while maintaining movement consciousness and educational excellence. This transformation would particularly resonate with educated, successful Jewish professionals seeking meaningful religious engagement in an era of unprecedented Jewish security and prosperity.
