RESTORATION OF THE ARMENIAN CHURCH HIERARCHY UNDER ANANIA MOKATSI (942-965) – 2023-3 Vardan A. Aleksanyan During the long reign of the famous leader of the 10th century, Anania Mokatsi, the Armenian Church faced various internal and external challenges directed against the national-church structures. Anania Mokatsi ascends the throne of the spiritual ruler during the period (during the 40s of the 10th century) of the weakening of the Catholicos power, when national and spiritual unity was threatened. The restoration of the spiritual and religious unity of the country, the establishment of social solidarity were the main guarantees of national security.
