(RNS) — Days after the Supreme Court ruled that Boston had violated a Christian group's rights by denying a request to fly its flag over Boston's City Hall Plaza, the Satanic Temple, a religious freedom advocacy group, has applied to fly its flag during "Satanic Appreciation Week" later this summer.

The Satanic Temple's aim is to test whether the city's court-ordered acceptance of flags from religious groups includes a commitment to plurality.

"A public forum that allows for religious expression can either announce a dedication to religious pluralism," said Lucien Greaves, Satanic Temple's co-founder and president, "or it can signal a decline into theocracy by allowing public representatives to dictate limits on the civic capacities of some religious identities by exercising exclusive preference for others."

The city did not respond to a request for comment.

In July 2017, Harold Shurtleff, director of Camp Constitution, a New Hampshire-based organization that seeks to teach families about "(America's) Judeo-Christian moral heritage," applied to fly a Christian flag in City Hall Plaza during an hour-long ceremony commemorating Constitution Day, September 17. In the past the city has flown flags honoring various countries, groups and causes. Boston did not have any guidelines on what flags can be flown.

Shurtleff's request was declined by Boston officials on the grounds that the religious flag would violate the First Amendment's establishment clause, disallowing support for any religion by the federal government. Shurtleff sued, and while intermediate courts sided with the city, on Monday, the Supreme Court concluded that "the city's refusal to let Shurtleff and Camp Constitution fly their flag based on its religious viewpoint violated the Free Speech Clause of the First Amendment."

Justice Kavanaugh, in a concurring opinion, wrote, "Under the Constitution, a government may not treat religious persons, religious organizations, or religious speech as second-class."

Shortly after the decision was announced, there were calls on social media for The Satanic Temple to apply to hoist a flag in Boston. The Salem-based organization did not disappoint.

"Far from being an arbitrary exercise in hilarity — as we often see our claims for equal access contextualized in the press," Greaves told Religion News Service, "our demands that the government respect viewpoint neutrality in a public forum has profound consequences for anybody concerned with the preservation of their civil liberties, regardless of their religious identification."
