In “Federalist 51,” James Madison wrote, “In a free government the security for civil rights must be the same as that for religious rights.” He went on to explain that for religious rights to be secure, pluralism is needed. Religious rights, he explained, “consists in the one case in the multiplicity of interests, and in the other in the multiplicity of sects. The degree of security in both cases will depend on the number of interests and sects…” Put simply, greater religious diversity equals greater religious liberty.
