The reasons for the disagreement between the ecclesiastical and secular authorities of the 17th century?

In the 17th century, anti-church movements were outlined in Russia. At the same time, in conditions of war, the government needed funds and labor resources. The Christian Church in Russia was a rich organization, so it was from its foundation that the tsars began to draw resources when ordinary people could not provide the front. Under Alexei Mikhailovich Nikon carried out church reform, which met with dissatisfaction on the part of the majority of the people. After it was held, the patriarch began to claim supremacy over secular power. This affected the relationship.
