National church

A national church is a Christian church associated with a specific ethnic group or a nation-state. This concept links religious identity with national or cultural identity. It is not just about personal faith. It is about how a group of people defines itself through its traditions. The idea became especially prominent during the 19th century. This was a time when modern nationalism was emerging across the world. People were beginning to see their religion as a core part of their national character.

There are different ways a church can be considered "national." One way is through the role of a state church, also known as an established church. In this system, the government may officially recognize and protect a specific denomination. For example, the Church of Greece is recognized by the constitution. It is described as the prevailing religion of the country. You might see the Greek flag or coat of arms displayed at these church properties. Another way is through the concept of a "folk church." This is common in some Lutheran traditions in Scandinavia. These churches are seen as national in an ethnic sense rather than a legal state sense. This movement grew in the second half of the 19th century following the ideas of Grundtvig.

Historical thinkers have debated what a national church actually means. In 1828, Samuel Taylor Coleridge wrote about the relationship between church and state. He suggested that a national church could exist even without Christianity. He pointed to older religious structures as evidence. He mentioned the Levitical Church in the Hebrew Constitution. He also noted the Druidical traditions of the Celts. Later, in 1911, John Wordsworth, the Bishop of Salisbury, wrote about this concept too. He interpreted the Church of Sweden and the Church of England as national churches. He saw them as specific institutions for the Swedish and English peoples.

Many countries have high percentages of people belonging to these national churches. In Armenia, 95.2% of the population belonged to the Armenian Apostolic Church in 2022. The Church of Cyprus had an 89.1% membership rate in 2011. In Greece, the Church of Greece had 90% membership in 2017. Other examples include the Church of Denmark, which had 74.3% membership in 2020. In Iceland, the Lutheran Church had 59% membership in 2022. The Church of Tuvalu is also very large, with over 91% membership in 2012. These numbers show how deeply these churches are woven into the population.

Data regarding religious membership can sometimes vary based on how it is collected. In Russia, there is no official census for religion. Researchers must rely on different surveys to find estimates. In 2012, an organization called ARENA found that 46.8% of Russians were Christian. However, other groups found much higher numbers. The Levada Center found 76% in late 2012. The Public Opinion Foundation found 65% in June 2013. Other studies from Pew and VTSIOM found numbers between 73.3% and 77%. This shows how complex it can be to measure religious identity in large nations.

National churches also connect to specific ethnic groups across different regions. For example, various groups in Indonesia have distinct Christian traditions. The Javanese, Balinese, and Batak people all have different church affiliations. Some of these groups follow Calvinist traditions, such as the Karo Batak. Others, like the Dayak people, follow the Evangelical Church in Kalimantan. In the Middle East, many ethnic groups are tied to specific denominations. The Copts are linked to the Coptic Orthodox Church of Alexandria. Maronites are associated with the Maronite Catholic Church. These connections help preserve the unique history of each ethnic group.

Not all thinkers believe that linking religion to a nation is a positive thing. Some have argued that this connection can cause problems. The theologian Karl Barth was a notable critic of this idea. He called the tendency to "nationalize" the Christian God heretical. He was particularly concerned during World War I. He feared that national churches might sanction warfare against other Christian nations. This critique highlights the tension between religious faith and national loyalty. It remains a significant topic in the study of how religion and politics interact.
