Finnish Orthodox Church
The Finnish Orthodox Church (; ), or Orthodox Church of Finland, is an autonomous Eastern Orthodox archdiocese of the Ecumenical 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 60,000 members that account for 1.1 percent of the native population of Finland. The parish of Helsinki has the most adherents.
