Donetsk separatists consider Christian denominations such as the Ukrainian Orthodox Church – Kyiv Patriarchate, Ukrainian Autocephalous Orthodox Church, Ukrainian Greek Catholic Church and wider Roman Catholic Church, and Protestantism, as all being anti-Russian and see them as obstacles in the path of the separatist goal of uniting the region with Russia. To complement this emphasis on Orthodoxy against churches deemed "heretical" and anti-Russian, the separatists have been successful in enlisting the widespread support of many people in Donetsk belonging to the indigenous Greek Orthodox community. These are mainly Pontic Greeks settled in Donetsk and elsewhere in southern Russia and Ukraine since the Middle Ages, and are in the main descendants of refugees from the Pontic Alps, Eastern Anatolia, and the Crimea, dating to the Ottoman conquests of these regions in the late 15th century. There have been widespread media reports of these ethnic Greeks and those with roots in southern Ukraine now living in mainly Northern Greece fighting with Donetsk separatist forces on the justification that their war represents a struggle for Christian Orthodoxy against the forces of what they often describe as "schismatics" and "fascists".
