Central Ukraine
According to a 2016 survey of religion in Ukraine held by the Razumkov Center, approximately 73.5% of the population of central Ukraine declared to be believers, while 4.8% declared to be non-believers, and 2.6% declared to be atheist. Of the total population, 86.5% were Christians (76.7% Eastern Orthodox, 6.5% simply Christians, 1.9% Latin Rite Catholics, 1.0% members of various Protestant churches, and 0.4% members of the Ukrainian Greek Catholic Church), 0.3% were Jewish, and 0.1% were Muslims. Not religious and other believers not identifying with any of the listed major religious institutions constituted about 12.8% of the population.
Ukrainian Orthodox Church (Moscow Patriarchate)
The Ukrainian Orthodox Church (UOC; ; ), commonly referred to as the Ukrainian Orthodox Church of the Moscow Patriarchate (UOC-MP, ) is a member of the Eastern Orthodox communion. It is one of two major Eastern Orthodox ecclesiastical bodies in modern Ukraine. It is a constituent part of the Russian Orthodox Church (ROC); however, the Ecumenical Patriarchate, the senior-most of all the Orthodox Churches and the mother church for the historical Russian Church, disputes the legality of the ROC's ecclesiastical jurisdiction over Ukraine, which in the modern era dates back to 1686. The current statutes of the ROC define it as a "self-governing [church] with the rights of wide autonomy". the status of the UOC-MP within the Moscow Patriarchate meant that it enjoyed full administrative independence from the ROC's Holy Synod, whereas the Primate of the UOC-MP was the most senior permanent member of the ROC's Holy Synod and thus had a say in its decision-making in respect of the rest of the ROC, including its administration in the Russian Federation.
