Readers are offered the book "Sylvester II, Prince Svyatopolk-Chetvertinsky, Bishop of Mogilev, and the state of the Orthodox Church in the Mogilev Diocese" by Ivan Mikhailovich Petropavlovsky, spiritual writer, teacher of the Mogilev Theological Seminary. The book is dedicated to the time of the bishopric of Sylvester II, 1704-1728. This time attracts attention by the fact that its beginning coincides with the events of the great Northern War, which, taking place in Belarus, caused many disasters of the Orthodox Church in the Mogilev diocese in general and especially in its main city - Mogilev. It begins the strongest persecution of the Orthodox of Belarus, undertaken with special energy by the Latins of Poland to implement the long-conceived and by that time in full and final form drawn up and printed plan for the eradication of the Russian faith and nationality in Poland.
