"We were hoping the court would realize that we are not a threat," said Robert Warren, a spokesman for the Witnesses based in their New York world headquarters. "But now the environment is worse than ever."
The court decision, say Jehovah's Witnesses officials and human rights experts, has not been fully enforced. Worship, reports from the country indicate, continues at some of the "Kingdom Halls" that serve Russia's more than 100,000 Witnesses.
But the possibility that the government will completely shut down the Jehovah's Witnesses looms.
While Jehovah's Witnesses prepare an appeal — and take heart in the condemnation of the court ruling from national and international bodies, including the U.S. State Department — they are not optimistic about a reversal of the ruling. And they worry for their brethren over the border in Kazakhstan, a former Soviet republic.
"In some ways the situation in Kazakhstan has deteriorated even faster," said Felix Corley, an Norway-based religious rights activist who edits the Forum 18 News Service, which tracks abuses in the former Soviet Union and Eastern Europe.
Earlier this month, a 61-year-old Jehovah's Witness from Kazakhstan — a retired bus driver battling cancer — was sentenced to five years in prison and banned from preaching for three years after he gets out.
A court convicted Teymur Akhmedov of inciting "ethnic, social, religious, family, and racial hatred." Jehovah's Witnesses said he peacefully shared his beliefs with a group of young men who asked him questions about his faith.
Witnesses are working on Akhmedov's appeal and say that since the Russian Supreme Court decision, anti-Witness propaganda has spread in Kazakhstan. Recently a popular television channel there reported that Jehovah's Witnesses in Russia plan a bombing, and speculated that the same could happen in Kazakhstan, said Bekzat Smagulov, a Jehovah's Witness and spokesman on the Akhmedov case.
"Most people are afraid," Smagulov said of Kazakhstan's 18,000 Witnesses.
In Russia, where authorities have officially declared the group illegal, fears run even higher. The surveillance and prosecution of the Witnesses began decades ago and involves all levels of government and law enforcement — from the Justice Ministry to the FSB (the successor to the KGB) to local police.
But Russia can't honestly fear violence from the Jehovah's Witnesses, said Corley. "I cannot believe they think they're going to go out and kill people."
Yet the court last month, after six days and 30 hours of testimony, deemed the Jehovah's Witnesses a threat to the state, commanded a halt to all their activity and allowed for the seizure of their property.
Rachel Denber, deputy director of the Europe and Central Asia division at Human Rights Watch, the international nonprofit, called the case against the Witnesses "absurd."
Specifically, Russian prosecutors accused the group of breaking a 2002 anti-extremism law — a statute human right activists say the government uses to harass groups Putin and his allies disfavor.
That law prohibits any group, except the Orthodox Church and a few other traditions, from claiming the true path to salvation. The Jehovah's Witnesses, like many denominations, make such a claim, Denber said, but not in a way that should land them on the same list of outlaws that includes al-Qaida and the Islamic State group.
The Witnesses' Western ties are also particularly suspect in today's Russia, which seeks to challenge the West as an international power broker, Denber said.
