Is there a so-called god in Russia? What do they believe in?

Russia is mostly practicing Orthodox Christianity.

The Orthodox Church emphasizes orthodoxy, so it is also called Orthodox Christianity. It differs from Catholicism in the following ways:

1. Conservatism: it adheres to the ancient teachings and liturgy, and basically does not make any adjustments.

2. Closedness: less emphasis was placed on missionary work, and there was little enthusiasm for exchanges and dialogue with Catholicism and Protestantism.

3. Dependence: historically, it has always been strongly dependent on the secular regime and subject to its strict control, unlike the Catholic Church which has always been secular and secular.

4. Decentralization: There has never been a unified global head of the Church. Nominally, the Patriarch of Constantinople (i.e., present-day Istanbul) was in the chief position, but in practice the Patriarch of Moscow, the Patriarch of Jerusalem, the Patriarch of Antioch, and the Patriarch of Alexandria were not subject to his control, and the influence of these Patriarchs on non-national Orthodox jurisdictions was also very limited.

5. Mystical: Emphasizing direct communion with God through contemplative meditation in prayer, much attention is paid to this individual and unrepeatable experience of faith.

Clergy below the level of bishop may marry (except for friars and nuns). But those clergy at the lower levels who have families, such as priests, have no chance of rising to bishoprics and above.

Orthodox churches have no statues inside or outside, as a result of the "iconoclasm" in Byzantium in the 8th and 9th centuries. However, there are a large number of frescoes in the churches, which reflect the religious content. Orthodox churches are richer in other decorations than Catholic churches, and the religious ceremonies are more elaborate.

Orthodox churches generally do not have pews, and parishioners are expected to stand for religious services. This is in stark contrast to Catholic and Protestant churches.

Orthodoxy has far less international influence than Catholicism and Christianity.
