Religion in Slovenia

The dominant religion in Slovenia is Christianity, primarily the Catholic Church, which is the largest Christian denomination in the country. Other Christian groups having significant followings in the country include Eastern Orthodoxy and Protestantism (Lutheranism). Islam, Judaism and Hinduism are small minorities in Slovenia. About 18% of the population are either agnostic or atheist.
Religion played a significant role in the development of the Slovenian nation and of 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 (which ousted religion from the public life), a degree of separation of the state and the church has been reached in independent Slovenia. In February 2007 Slovenia passed a new Religious Freedom Act with a bias towards the Catholic Church (particularly in regard to state funding) and strict terms for the registration of new religious communities.

The Catholic Church in Slovenia is part of the worldwide Catholic Church, under the spiritual leadership of the Pope in Rome.
There are around 1,135,626 Catholics in the country (about 57.8% 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.
Protestantism is tightly-knit with the history of Slovenians, with the Slovenian language having been established in the Reformation. Primož 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.

Religious freedom.
Slovenia's laws guarantee the freedom of religion and establish a separation between church and state, as well as prohibiting religious discrimination and religious hatred. Religious groups may easily register with the government in order to receive some privileges, largely consisting of various forms of monetary compensation.
Slovenia's laws prohibit circumcision for non-medical reasons and animal slaughtering practices that are necessary for meat to be considered kosher or halal. Members of the Jewish and Muslim communities observe these practices outside of the country (importing meat, and traveling to neighboring countries for religious circumcision) without obstruction from Slovenia's government.
