Canonical Principles of the Autocephalous System of the Ecumenical Church in the Administrative Structure of the Byzantine Empire

The article analyzes the body of legal norms of church law, which regulates the autocephalous principle of the church. The vector of modern transformation of autocephalous issues determines the revision of traditional approaches and reflects the ecclesiological dimension of modern Orthodoxy. The article reveals the essence of the earthly rule of the "heavenly Church", which is subordinated to the church's mission in finding the way to salvation. It is proved that the internal church system is of practical importance for the process of autocephaly of the new national local churches, which gained independence in the late nineteenth and twentieth centuries. The article examines that the church canons adopted and endorsed by the emperor in the Code of Justinian the Great in the era of the Ecumenical Councils, are relevant today. These rules, which are universally binding, may be repealed by the new All-Orthodox Council. This is important for a number of modern national churches that defend their canonical rights for independence and universal recognition. The study found that since the Byzantine Empire, state power has imposed its own principle of administrative division and management methods. Already in the II-III centuries a clear hierarchical structure of church management was formed, which led to the formation of ancient patriarchates. However, the founding of the first apostolic communities took place solely on the basis of the autocephalous principle.

It is concluded that Orthodox ecclesiology offers an alternative approach to churchadministrative management. It is proved that only the autocephalous system is the only acceptable variant of the existence of the Universal Orthodoxy. Therefore, the struggle of a number of national churches for independence and recognition is fair. The lack of clear regulation of the procedure for proclamation of a new autocephalous church is specified. Therefore, further scientific explorations of autocephalous topics and the canonical work of the Holy Fathers will complement the research.
