On October 2, 2013, the Synodal Hall of the official Patriarchal and Synodal Residence in the Danilov Stavropol Monastery in Moscow, chaired by His Holiness Patriarch Kirill of Moscow and All Russia, hosted a regular meeting of the Holy Synod of the Russian Orthodox Church.

At this meeting, it was decided to form the Gorno-Altai Diocese within the administrative borders of the Altai Republic, separating it from the Barnaul diocese. This decision was made on the basis of a report filed by Bishop Sergius of Barnaul and Altai addressed to His Holiness Patriarch Kirill of Moscow and All Russia, which, in particular, says: "I respectfully appeal to you with a request for the creation of an independent diocese by the Holy Synod on the territory of the Altai Republic. The Altai Republic is a dynamically developing subject of the Russian Federation, which is part of the Barnaul Diocese in ecclesiastical terms. In this regard, it seems very difficult, given the vastness of the territory, to carry out the spiritual and administrative management of two independent regions and at the same time fruitfully implement the decisions of the Bishops' Councils of 2011 and 2013 on increasing the number of parishes, clergy and the approach of the bishop to his flock. The population of the Altai Republic as of 2013 is 209 thousand people."
