The concept of the public welfare is broad and inclusive. The values it represents are spiritual as well as physical, aesthetic as well as monetary. It is within the power of the legislature to determine that the community should be beautiful as well as healthy, spacious as well as clean, well-balanced as well as carefully patrolled. . . . If those who govern the District of Columbia decide that the Nations Capital should be beautiful as well as sanitary, there is nothing in the Fifth Amendment that stands in the way.

No government shall impose or implement a land use regulation in a manner that imposes a substantial burden on the religious exercise of a person, including a religious assembly or institution, unless the government demonstrates that imposition of the burden on that person, assembly, or institution (A) is in furtherance of a compelling government interest; and (B) is the least restrictive means of furthering that compelling government interest.

[N]umerous state laws, such as the zoning regulations at issue here, impose a substantial burden on a large class of individuals. When the exercise of religion has been burdened in an incidental way by a law of general application, it does not follow that the persons affected have been burdened any more than other citizens, let alone burdened because of their religious beliefs.

If the holding in Keelerthat where the government provides an exception to its landmark preservation laws for secular reasons, it must also extend exceptions for religious reasonswas correct, then the holding in Smith would surely have been that where government exempts from prohibition certain secular, medical uses of drugs, it is required to exempt religious uses as well.
