He interpreted the spiritual connection of St. Eleazar of Anzersky, a native of Koezelsk, with Patriarch Nikon, his tonsured, as a relationship between an elder and a disciple.

The article is devoted to the embodiment of these ideas in the concept of the Museum of Patriarch Nikon and in other forms of veneration of Archimandrite. Leonidas of the great Archpastor.
