In Obergefell, I warned that the Court’s decision would “inevitabl[y] . . . come into conflict” with religious liberty, “as individuals . . . are confronted with demands to participate in and endorse civil marriages between same-sex couples.” 576 U. S., at ___ (dissenting opinion) (slip op., at 15). This case proves that the conflict has already emerged. Because the Court’s decision vindicates Phillips’ right to free exercise, it seems that religious liberty has lived to fight another day. But, in future cases, the freedom of speech could be essential to preventing Obergefell from being used to “stamp out every vestige of dissent” and “vilify Americans who are unwilling to assent to the new orthodoxy.” Id., at ___ (ALITO, J., dissenting) (slip op., at 6). If that freedom is to maintain its vitality, reasoning like the Colorado Court of Appeals’ must be rejected.
