On Sunday 29 October, The King attended a celebratory service at Uppsala Cathedral in connection with the Reformation anniversary year. 2017 is the 500th anniversary of when Martin Luther posted his 95 theses against indulgence to the door of All Saints' Church in Wittenberg on 31 October 1517.
At Uppsala Cathedral, The King was welcomed by Archbishop Antje Jackelén, Chief Court Chaplain Bishop Johan Dalman and Dean Annica Anderbrant. In the vestibule, The King wrote in the cathedral's guest book.
The theme for the service was "I am not ashamed of the gospel – the 500th anniversary of the Reformation". The service was opened by Jakob Schwarz, children from the Church of Sweden and Archbishop Antje Jackelén.
Chief Court Chaplain Bishop Johan Dalman assisted the archbishop in administering the Holy Communion.
During the service, Prime Minister Stefan Löfven gave an address.
The Reformation is the name given to the movements within Western Christianity that lasted for several centuries beginning in the 13th century, and resulted in various Protestant or Reformed communions such as the Lutheran, Reformed and Anglican churches, as well as Radical Reformation groups such as the Anabaptists and the Unitarians, who branched away from the Roman Catholic Church in the 16th century. The word 'reformation' comes from the Latin 'reformatio', meaning 'to restore something to its original form' or 'to renew'.
