The dominant religion in Slovenia is Christianity, primarily the Catholic Church, which is the largest Christian denomination in the country. Other Christian religions having significant followings in the country are Eastern Orthodoxy, Protestantism (Lutheranism). Islam (2.4%). Judaism and Hinduism are small minorities in Slovenia. About 10% are either agnostic or atheist.
Religion played a significant role in the development of the Slovenian nation and the country of Slovenia. After a centuries-long tradition of a state church, interrupted by the periods of Protestant Reformation in the 16th century and post-World War II socialism ousting religion from the public life, a degree of separation of the state and the church has been reached in the independent Slovenia. In February 2007 a new Religious Freedom Act was passed in Slovenia, with a bias towards the Catholic Church, particularly in regard to state funding and the strict terms for the registration of new religious communities.
There are around 1,471,000 Catholics in the country (about 73,5% of the total population as per the 2002 Census). The country is divided into six dioceses, including two archdioceses. The diocese of Maribor was elevated to an archdiocese by Pope Benedict XVI in 2006. Additionally, the pope created three new sees, namely Novo Mesto, Celje and Murska Sobota.
Protestantism is tightly-knit with the history of Slovenians, with the Slovenian language having been established in the Reformation. Primo? Trubar was a leading early Slovenian author and a Protestant reformer. He contributed to the development of the Slovenian language and Slovenian culture.
The Reformation flourished in the 16th century, accounting for the vast majority of cultural development in Slovenian. Lutheranism was the most popular Protestant denomination among Slovenians, with minorities, most notably Calvinism.
Protestantism among Slovenians was aggressively attempted to be wiped out by the Habsburgs with the Counter-Reformation. The Counter-Reformation was heavily deployed to the majority of Slovenian-speaking territory. Means used involved murder, extradition, book-burning and a general ban of the Slovenian language. Excluded were eastern regions (such as Prekmurje), ruled by Hungarian nobility, often Calvinist. Historically, Hungarians had taken up Lutheranism first, before gradually switching to Calvinism. They did not have a policy of extinguishing Lutheranism.
Protestantism among Slovenians survived the Counter-Reformation scattered. Protestantism is a minority group of Christian denominations in the Republic of Slovenia today. The largest community of Protestant Slovenians lives in the Prekmurje region, most of them are Lutheran.
Eastern Orthodoxy maintains a significant presence in the country and is practised in majority by Slovenians of Serbian heritage. Eastern Orthodox Christians in Slovenia are under ecclesiastical jurisdiction of the Serbian Orthodox Metropolitanate of Zagreb and Ljubljana.
The Muslims in Slovenia are ethnically mostly Bosniaks and other Slavic Muslims. In 2014, there were 48,266 Muslims in Slovenia, making up about 2.4 percent of the total population. The Muslim community of Slovenia is headed by Ned?ad Grabus.
According to the published data from the 2002 Slovenian census, out of a total of 47,488 Muslims (2.4% of the total population) 2,804 Muslims (5.90% of the total Muslims in Slovenia) declared themselves as ethnic Slovenian Muslims.
There are also Muslims from Central, South and Southeast Asia, who are not counted in the census because they are migrant workers.
The small Jewish community of Slovenia (Slovene: Judovska skupnost Slovenije) is estimated at 400 to 600 members, with the Jewish community of Slovenia suggesting 500 to 1000 members. Around 130 are officially registered, most of whom live in the capital, Ljubljana. The Jewish community was devastated by the Shoah, and has never fully recovered. Until 2003, Ljubljana was the only European capital city without a Jewish place of worship.
