Abstract
The Supreme Court's recent embrace of "historical practices and understandings" in interpreting the Establishment Clause has emboldened states to challenge forty-five years of precedent prohibiting Ten Commandments displays in public schools. Yet, these states advance a version of history that mistakenly ignores European religious persecution that shaped how the Founders understood the establishment of religion. This Essay remedies that error through a novel historical analogy: sixteenth-century Catholic processions that forced Protestants to choose between betraying their conscience or marking themselves for persecution. Like modern students confronting state-mandated religious texts, Reformation-era dissenters faced orchestrated tests of faith designed to identify and marginalize religious minorities. By recovering this history, this Essay demonstrates that classroom religious displays violate not just modern sensibilities but a historical understanding of religious freedom that refugees carried to American shores.
