What significance did the Church have in the life of Russian society in the 19th century?

Russia in the 19th century reached the peak of its religious enlightenment. Although it was a religious state, there was a strong religious structure under the protection of the emperor. He was considered the supreme defender of all church dogmas, and the church itself had the right to persecute and eradicate heresies among the people. Since ancient times, the Church has been the richest feudal lord, and by the 19th century it had only strengthened its power and financial condition. In addition, she more and more merged with the power and had pressure on the king.
