What is the key religion of Russia?

Answer 1

It is a form of Christianity known as the Russian Orthodox Church. It is a conservative religion that is not part of the Roman Communion; it is not under the authority of the Bishop of Rome. Russian Orthodoxy is an important religion in Russia, but it is not the official religion of Russia. There is no official connection between Orthodoxy and the Russian government as there was prior to the revolution. During the height of communist power in Russia, the church was severely restricted.
