  Protestants refer to specific groupings of congregations or churches that share in common foundational doctrines and the name of their groups as denominations. The term denomination (national body) is to be distinguished from branch (denominational family; tradition), communion (international body) and congregation (church). An example (this is no universal way to classify Protestant churches, as these may sometimes vary broadly in their structures) to show the difference:
  
  Protestants reject the Catholic Church 's doctrine that it is the one true church, with some teaching belief in the invisible church, which consists of all who profess faith in Jesus Christ. The Lutheran Church traditionally sees itself as the "main trunk of the historical Christian Tree" founded by Christ and the Apostles, holding that during the Reformation, the Church of Rome fell away. Individual denominations also have formed over very subtle theological differences. Other denominations are simply regional or ethnic expressions of the same beliefs. Because the five solas are the main tenets of the Protestant faith, non-denominational groups and organizations are also considered Protestant.
  
  Various ecumenical movements have attempted cooperation or reorganization of the various divided Protestant denominations, according to various models of union, but divisions continue to outpace unions, as there is no overarching authority to which any of the churches owe allegiance, which can authoritatively define the faith. Most denominations share common beliefs in the major aspects of the Christian faith while differing in many secondary doctrines, although what is major and what is secondary is a matter of idiosyncratic belief.
  
  Several countries have established their national churches, linking the ecclesiastical structure with the state. Jurisdictions where a Protestant denomination has been established as a state religion include several Nordic countries; Denmark (including Greenland), the Faroe Islands (its church being independent since 2007), Iceland and Norway have established Evangelical Lutheran churches. Tuvalu has the only established church in Reformed tradition in the world, while Tonga — in the Methodist tradition.
  
  The Church of England is the officially established religious institution in England, and also the Mother Church of the worldwide Anglican Communion.
  
  In 1869, Finland was the first Nordic country to disestablish its Evangelical Lutheran church by introducing the Church Act. Although the church still maintains a special relationship with the state, it is not described as a state religion in the Finnish Constitution or other laws passed by the Finnish Parliament. In 2000, Sweden was the second Nordic country to do so.
