How did Peter the Great limit the power if the church in russia?

Peter the Great limited the power of the Russian Orthodox Church by abolishing the position of Patriarch in 1721 and replacing it with the Holy Synod, which placed church governance under state control. This move centralized religious authority in the hands of the state, allowing Peter to appoint bishops and control church policies. Additionally, he reduced the church's influence in governance and implemented reforms that emphasized secularism, aligning the church more closely with his vision of a modernized Russia.
