Romanian Orthodox Church in the context of "Petru Groza"

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. Moldovans are overwhelmingly adherents of Eastern Orthodoxy. According to the 2024 Moldovan census, 95.2 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 (formally known as Metropolis of Chișinău and All Moldova) 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.

Christianity is the main religion in Romania, with Romanian Orthodoxy being its largest denomination.

The National Cathedral (Romanian: Catedrala Națională), also known as the People's Salvation Cathedral (Romanian: Catedrala Mântuirii Neamului), is an Eastern Orthodox cathedral in Bucharest, Romania, built to serve as the patriarchal cathedral of the Romanian Orthodox Church. It is located in central Bucharest on Spirea's Hill (Arsenal Square), facing the Palace of Parliament. At 127 metres (417 ft) tall, the cathedral occupies a dominant position in Bucharest's cityscape, being visible from all approaches to the city.

It is the tallest and largest Eastern Orthodox church building by volume, and area, in the world. The People's Salvation Cathedral will have the largest collection of church mosaics (interior decoration) in the world when it is completed, having about 25,000 square meters. Also the People's Salvation Cathedral has the world's largest Orthodox iconostasis (23.8 meters long and 17.1 meters high) and the world's largest free-swinging church bell.

The Patriarch of All Romania (Romanian: Patriarh al Întregii Românii; Romanian pronunciation: [patriˈarh al ɨnˈtred͡ʒi romɨˈni]) is the title of the head of the Romanian Orthodox Church. The Patriarch is officially styled as Archbishop of Bucharest, Metropolitan of Muntenia and Dobruja, Locum tenens of the throne of Caesarea Cappadociae and Patriarch of the Romanian Orthodox Church. The current patriarch Daniel acceded to this position on 12 September 2007.

The Metropolis of Chișinău and All Moldova (Romanian: Mitropolia Chișinăului și a întregii Moldove; Russian: Кишинёвско-Молдавская митрополия, romanized: Kishinyovsko-Moldavskaya mitropoliya), also referred to as the Moldovan Orthodox Church (Romanian: Biserica Ortodoxă din Moldova; Russian: Православная церковь Молдовы, romanized: Pravoslavnaya tserkov Moldovy), is an autonomous metropolitanate under the Russian Orthodox Church. Its canonical territory is the Republic of Moldova.

The Metropolis of Chișinău and All Moldova is the largest church in the country, and one of the two main Orthodox churches in Moldova, along side the Metropolis of Bessarabia, an autonomous metropolitanate of the Romanian Orthodox Church. In the 2004 census in Moldova 3,158,015 people or 95.5% of those declaring a religion claimed to be Eastern Orthodox Christians of all rites.

The Metropolis of Bessarabia (Romanian: Mitropolia Basarabiei), also referred to as the Bessarabian Orthodox Church, is an autonomous Eastern Orthodox Metropolitan bishopric of the Romanian Orthodox Church, situated in Moldova. Its canonical jurisdiction is the territory of the Republic of Moldova, and over the Moldovan and Romanian Orthodox diaspora from the former USSR.

The Metropolis of Bessarabia was created in 1918, as the Archbishopric of Chișinău, and organized as a Metropolis, in 1927. Inactive during the Soviet occupation of Bessarabia (1940–1941) and the Soviet rule in Moldova (1944–1991), the Metropolis of Bessarabia was re-activated on 14 September 1992, and raised to the rank of exarchate, in 1995. The current Metropolitan of Bessarabia is Petru (Păduraru).

The Orthodox Cathedral (Romanian: Catedrala Ortodoxă), also known as the Metropolitan Cathedral (Romanian: Catedrala Mitropolitană), is a Romanian Orthodox church in Timișoara. The cathedral is the seat of the Archbishopric of Timișoara and the Metropolis of Banat. It is dedicated to the Three Holy Hierarchs, Basil the Great, Gregory the Theologian and John Chrysostom.

Built on an area of 1,542 m, it has 11 towers, of which the central one has a height of 90.5 m, making it the second tallest church in Romania, after the People's Salvation Cathedral in Bucharest. The cathedral is listed in the National Register of Historic Monuments.

A suffragan diocese is one of the dioceses other than the metropolitan archdiocese that constitute an ecclesiastical province. It exists in some Christian denominations, in particular the Catholic Church, the Coptic Orthodox Church of Alexandria, and the Romanian Orthodox Church.

In the Catholic Church, although such a diocese is governed by its own bishop or ordinary, who is the suffragan bishop, the metropolitan archbishop has in its regard certain rights and duties of oversight. He has no power of governance within a suffragan diocese, but has some limited rights and duties to intervene in cases of neglect by the authorities of the diocese itself.

Bulgarians (Romanian: bulgari) are a recognized minority in Romania (Bulgarian: Румъния, Rumaniya), numbering 7,336 according to the 2011 Romanian census, down from 8,025 in 2002. Despite their low census number today, Bulgarians from different confessional and regional backgrounds have had ethnic communities in various regions of Romania, and during the Middle Ages Bulgarian culture has exerted considerable influence on its northern neighbour. According to one Bulgarian estimate, Romanian citizens of Bulgarian origin number around 250,000. According to the Romanian census of 2021, among the 5,975 ethnic Bulgarians, 3,583 were Roman Catholics, 1,977 were Romanian Orthodox and 21 were Serbian Orthodox.

Historically, Bulgarian communities in modern Romania have existed in Wallachia (Bulgarian: Влашко, transliterated: Vlashko), Northern Dobruja (Bulgarian: Северна Добруджа, translit. Severna Dobrudzha) and Transylvania (Bulgarian: Седмиградско, translit. Sedmigradsko). Currently, however, the Bulgarian community in present-day Romania that has retained most efficiently its numbers, social integrity and strong ethnic identity is that of the Banat Bulgarians, a Roman Catholic minority in the Banat who account for the bulk of the Bulgarian-identifying population of Romania. In Wallachia, there are only few Bulgarians who have preserved their national identity, though the numbers of those who speak Bulgarian and affirm to have Bulgarian ancestors is still high.
