The Finnish Orthodox Church is an autonomous Orthodox archbishopric of the Patriarchate of Constantinople. The Church has a legal position as a national church in the country, along with the Evangelical Lutheran Church of Finland. With its roots in the medieval Novgorodian missionary work in Karelia, the Finnish Orthodox Church was a part of the Russian Orthodox Church until 1923. Today the church has three dioceses and 58,000 members that account for 1.1% of the population of Finland. The parish of Helsinki has the most adherents.
