[T]he Roberts Court, having worked assiduously over the last 10 years to elevate the First Amendment’s Free Exercise Clause at the expense of its First Amendment twin, the Establishment Clause, is now approaching a moment of truth. To accept the claims being made here is to plunge into a world where conviction clothed in religious garb, no matter how untethered from reality, can be permitted to impair the rights of non-adherents to the benefits designed by a secular government to apply to all. Such a “sweeping understanding” of the Religious Freedom Restoration Act, Solicitor General Verrilli’s brief tells the court, “is inconsistent with our nation’s traditions and finds no support in this court’s precedents.”
