Russian culture
Christianity, Islam, Buddhism, and Judaism are Russia's traditional religions, deemed part of Russia's "historical heritage" in a law passed in 1997.
Estimates of believers widely fluctuate among sources, and some reports put the number of non-believers in Russia as high as 16–48% of the population. Russian Orthodoxy is the dominant religion in Russia. 95% of the registered Orthodox parishes belong to the Russian Orthodox Church while there are a number of smaller Orthodox Churches. However, the vast majority of Orthodox believers do not attend church on a regular basis. Nonetheless, the church is widely respected by both believers and nonbelievers, who see it as a symbol of Russian heritage and culture. Smaller Christian denominations such as Roman Catholics, Armenian Gregorians, and various Protestants exist.
