Whether the Establishment Clause permits government use of religious symbols whenever the government does not coerce religious observance.
Holding
No. Coercion is not a necessary element of an Establishment Clause violation; government may not endorse, favor, or promote religious belief.
Reasoning
The Court applied the familiar Lemon framework, focusing on whether a government practice has the effect of advancing religion. In symbolic-display cases, that effects inquiry asks whether the government’s action would reasonably be understood as endorsing or disapproving religion.
Drawing on Justice O’Connor’s concurrence in Lynch v. Donnelly, the Court explained that endorsement makes religious adherence relevant to a person’s standing in the political community. It sends nonadherents the message that they are outsiders and adherents the message that they are favored insiders.
The meaning of a religious symbol depends on its context and particular physical setting. A religious object does not lose its religious content merely because government places it in a holiday display, but surrounding circumstances may affect whether a reasonable observer would attribute an endorsement of the symbol’s religious message to the government.
