While Orthodox Christianity is the dominant form of religion in Montenegro, there are also sizable numbers of adherents of both Islam and Catholic Christianity. The dominant Church is the Serbian Orthodox Church although traces of a forming Montenegrin Orthodox Church are present.
The results of the Montenegrin census of 2011 by ethnic groups, the latest census in which the indication of identification (whether by confession or as irreligious) in the question for confession was obligatory, are as follows:
Orthodox Christianity is the dominant religion in Montenegro. Adherents of Orthodox Christianity in Montenegro are predominantly Montenegrins and Serbs. Ethnic Serbs in Montenegro are adherents of the Serbian Orthodox Church and its dioceses in Montenegro: Metropolitanate of Montenegro and the Littoral, Eparchy of Budimlja and Nik?i? and Eparchy of Mile?eva. Ethnic Montenegrins are divided between the Serbian Orthodox Church and the Montenegrin Orthodox Church (which is still in its phase of conceivement and is non-canonical and unrecognized).
The current Metropolitan bishop is Amfilohije Radovi?. He is a vocal supporter of Russia and has repeatedly denounced NATO; calling its actions similar to that of the Ottoman Empire and that the organization is a "national fascist pact."
Muslims in Montenegro are divided into two main groups, and further subgroups:
Islam is the dominant religion in the northeastern municipalities, which are part of the Sand?ak geographical region, and in municipalities where Albanians form a majority. Islam is the majority religion in Ro?aje, Plav, Gusinje, Ulcinj and Petnjica.
Catholic Christianity is mostly present in the region of Boka Kotorska, where there is a significant presence of ethnic Croats. Also, a number of ethnic Albanians are adherents of Catholic Christianity.
In 2003 an Apostolic Exarchate was created for Greek Catholics in Serbia and Montenegro, headed by Bishop Djura D?ud?ar (born 1954, appointed 2003). It has 21 parishes and 22,720 faithful, consisting mostly of a group of ethnic Rusyn Greek Catholics in the region of Vojvodina.
In February 2012, the Montenegrin Prime Minister Igor Luk?i? signed an agreement with the Montenegrin Jewish community to grant official recognition of Jews as a minority in Montenegro. The agreement also established Judaism as the country's fourth official religion, along with the Catholic Church, Eastern Orthodox Christianity, and Islam.
The majority of Montenegro's population, 98.69%, declares to belong to a religion, though observance of their declared religion may vary widely.
On the census from 2011, atheists, those who declared no religion, comprised about 1.24% of the whole population, and agnostics 0.07%.
Municipalities with highest share of atheists are Herceg Novi (2.43%), Kotor (2.03%), Podgorica (1.99%) and Tivat (1.7%). In contrast, Ro?aje has the fewest atheists, who make up only 0.01% of its population.
In some municipalities more than half of population are undeclared, however.
