Christianity is the predominant religion in the Philippines, with Roman Catholicism being its largest denomination. Sizeable minorities adhering to Islam, Indian religions, and indigenous Philippine folk religions are also present.
Religion in Russia is diverse, with Orthodox Christianity being the most widely professed faith, but with significant minorities of non-religious people and adherents of other faiths. A 1997 law on religion recognises the right to freedom of conscience and creed to all the citizenry, the spiritual contribution of Orthodox Christianity to the history of Russia, and respect to "Christianity, Islam, Buddhism, Judaism and other religions and creeds which constitute an inseparable part of the historical heritage of Russia's peoples", including ethnic religions or paganism, either preserved, or revived. According to the law, any religious organisation may be recognised as "traditional", if it was already in existence before 1982, and each newly founded religious group has to provide its credentials and re-register yearly for fifteen years, and, in the meantime until eventual recognition, stay without rights.
Religion in Egypt controls many aspects of social life and is endorsed by law. The state religion of Egypt is Islam, although estimates vary greatly in the absence of official statistics. Since the 2006 census religion has been excluded, and thus available statistics are estimates made by religious and non-governmental agencies. The country is majority Sunni Muslim, with the next largest religious group being Coptic Orthodox Christians. The exact numbers are subject to controversy, with Christians alleging that they have been systemically under-counted in existing censuses.
Moldova's constitution provides for freedom of religion and complete separation of church and state, though the constitution cites the "exceptional importance" of Eastern Orthodox Christianity. Discrimination on the basis of religious affiliation is illegal, and incitement to religious and ethnic hatred was made illegal in May 2022. Religion in Moldova is dominated by the Eastern Orthodox branch of Christianity. According to the 2014 Moldovan census, 90 per cent of the country reported to be of the Eastern Orthodox Christian faith. Of this number, around eighty to 90 per cent of Orthodox Moldovans belong to the Moldovan Orthodox Church which is subordinate to the Russian Orthodox Church, and has played a powerful role in deepening Russia's influence in Moldova. The remaining 10–20 per cent of Orthodox Moldovans belong to the Metropolis of Bessarabia, which is subordinate to the Romanian Orthodox Church.
Religion has been a major influence on the societies, cultures, traditions, philosophies, artistic expressions and laws within present-day Europe. The largest religion in Europe is Christianity. However, irreligion and practical secularisation are also prominent in some countries. In Southeastern Europe, three countries have Muslim majorities, with Christianity being the second-largest religion in those countries. Ancient European religions included veneration for deities such as Zeus. Modern revival movements of these religions include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and others. Smaller religions include Indian religions, Judaism, and some East Asian religions, which are found in their largest groups in Britain, France, and Kalmykia.
The Catholic Church in Greece is part of the worldwide Catholic Church, under the spiritual leadership of the Pope in Rome. Indigenous Roman Catholic Greeks numbered about 50,000-70,000 in 2022 and were a religious and not an ethnic minority. Most of them are a remnant of Venetian and Genoese rule in southern Greece and many Greek islands from the early 13th until the late 18th century, Greeks who converted to Catholicism or descendants of the thousands of Bavarians that came to Greece in the 1830s as soldiers and civil administrators, accompanying King Otto. One very old but still common term to reference to them is Φράγκοι, or "Franks", dating to the times of the Byzantine Empire, when medieval Greeks would use that term to describe all Catholics.
Christianity is the predominant religion in Mexico, with Catholicism being its largest denomination representing around 78% of the total population as of 2020. In recent decades the share of Catholics has been declining, due to the growth of other Christian denominations – especially various Protestant churches, Jehovah's Witness and Mormonism – which now constitute larger shares of the population. Conversion to non-Catholic denominations has been considerably lower than in Central America, and central Mexico remains one of the most Catholic areas in the world.
Minorities in Greece are small in size compared to Balkan regional standards, and the country is largely ethnically homogeneous. This is mainly due to the population exchanges between Greece and neighboring Turkey and Bulgaria, which removed most Muslims and those Christian Slavs who did not identify as Greeks from Greek territory. The treaty also provided for the resettlement of ethnic Greeks from those countries, later to be followed by refugees. There is no official information for the size of the ethnic, linguistic and religious minorities because asking the population questions pertaining to the topic have been abolished since 1951.
As of 2011, most Armenians in Armenia are Christians (97%) and are members of the Armenian Apostolic Church, which is one of the oldest Christian churches. It was founded in the 1st century AD, and in 301 AD became the first branch of Christianity to become a state religion.
Religion in Italy has been historically characterised by the dominance of the Catholic Church since the East–West Schism, but, over the years, due to immigration, the influx of Muslims, Orthodox Christians, Protestants, Buddhists and Hindus, as well as proselytism, religious pluralism has increased. Italy also features a pre-Christian Jewish community and one of the largest shares of Jehovah's Witnesses in the world.
Christianity is the main religion in Romania, with Romanian Orthodoxy being its largest denomination.
Christianity is the predominant religion in Ukraine, with 85% of the population identifying as Christian according to a 2022 survey conducted by the Kyiv International Institute of Sociology (KIIS). Seventy-two percent of the population avowed fidelity to an Eastern Orthodox Church: 54% of Ukrainians proclaimed adherence to the autocephalous Orthodox Church of Ukraine; 14% identified as Orthodox Christian without specifying a church affiliation; 4% associated with the Moscow Patriarchate. Another 9% of Ukrainians professed devotion to the Catholic Church in Ukraine: 8% Ukrainian Greek Catholics and 1% Latin Catholics. Two percent of the population declared affiliation to a mainstream Protestant Church, and a further 2% identified with some alternative sect of Christianity.
Religion in Sweden has, over the years, become increasingly diverse. Christianity was the religion of virtually all of the Swedish population from the 12th to the early 20th century, but it has rapidly declined throughout the late 20th and early 21st century.
Christianity in Russia is the most widely professed religion in the country. The largest tradition is the Russian Orthodox Church. According to official sources, there are 170 eparchies of the Russian Orthodox Church, 145 of which are grouped in metropolitanates. There are from 500,000 to one million Old Believers, who represent an older form of Russian Orthodox Christianity, and who separated from the Orthodox Church in the 17th century as a protest against Patriarch Nikon's church reforms.
Christianity is the main religion in Belarus, with Eastern Orthodoxy being the largest denomination. The legacy of the state atheism of the Soviet era is evident in the fact that a part of the Belarusians are not religious. Moreover, other non-traditional and new religions have sprung up in the country after the end of the Soviet Union.
In 2020, 85.84% of the population in Georgia adhered to Christianity, 11% were Muslim, 0.1% were Jewish, 0.04% were Baha'i and 3% had no religious beliefs. Other religious groups include Jehovah's Witnesses and Yazidis. Orthodox churches serving other non-Georgian ethnic groups, such as Russians and Greeks, are subordinate to the Georgian Orthodox Church.
According to various polls, the majority of Kazakhstan's citizens, primarily ethnic Kazakhs, identify as Sunni Muslims. In 2020, Shia Muslims made up 0.55% of the population.
The Turkmen of Turkmenistan, are predominantly Muslims. According the U.S. Department of State's International Religious Freedom Report for 2022,
According to U.S. government estimates, the country is 89 percent Muslim, 9 percent Eastern Orthodox, and 2 percent other. There are small communities of Jehovah's Witnesses, Shia Muslims, Baha’is, Roman Catholics, the International Society for Krishna Consciousness, and evangelical Christians, including Baptists and Pentecostals. Most ethnic Russians and Armenians identify as Orthodox Christian and generally are members of the Russian Orthodox Church or Armenian Apostolic Church. Some ethnic Russians and Armenians are also members of smaller Protestant groups. There are small pockets of Shia Muslims, consisting largely of ethnic Iranians, Azeris, and Kurds, some located in Ashgabat, with others along the border with Iran and in the western city of Turkmenbashy.
The Constitution of Armenia as amended in December 2005 provides for freedom of religion; however, the law places some restrictions on the religious freedom of adherents of minority religious groups, and there were some restrictions in practice. The Armenian Apostolic Church, which has formal legal status as the national church, enjoys some privileges not available to other religious groups. Some denominations reported occasional discrimination by mid- or low-level government officials but found high-level officials to be tolerant. Jehovah's Witnesses reported that judges sentenced them to longer prison terms for evasion of alternative military service than in the past, although the sentences were still within the range allowed by law. Societal attitudes toward some minority religious groups were ambivalent, and there were reports of societal discrimination directed against members of these groups.
Estonia, historically a Lutheran Christian nation, is today one of the "least religious" countries in the world in terms of declared attitudes, with only 14 percent of the population declaring religion to be an important part of their daily life. This is thought to largely be a result of the Soviet occupation of Estonia in 1940, prior to which Estonia had a large Christian majority.
