Phillip Munoz has a worthy article in First Things on religious freedom and freedom of speech. His first paragraph (thanks to The Remedy):
"If conservative and liberal church-state scholars agree on one thing, it is that the Supreme Court’s religious liberty jurisprudence is a disaster. No single rule exists to guide decision making. The various doctrines employed are, at best, inconsistent and, at worst, blatantly contradictory. Divisions on the Court run so deep that actions demanded by “free exercise” according to some Justices violate “no-establishment” according to others. The result is an ever shifting, case-by-case jurisprudence based on narrow factual questions that encourages neither the rule of law nor a robust protection of religious freedom."
You might also take a look at Ken Blackwell’s (Ohios Secretary of State) piece called "Religious LIberty: The Most Precious of Our Liberties," in the current issue of On Principle.
