Pope Francis travels to Sweden Monday on a trip that marks the start of yearlong observances for the 500th anniversary of the Reformation. He will be meeting with the Lutheran World Federation, which was founded in Lund, Sweden 70 years ago. Some 10,000 people are expected to attend a joint Catholic-Lutheran conference and prayer service under the theme From Conflict to Communion – Together in Hope.

Francis will attend a Catholic-Lutheran prayer service at the Protestant cathedral of Lund on Oct. 31, the anniversay of Martin Luther nailing his 95 Theses to the door of a German cathedral, which questioned the sale of indulgences and the Gospel foundations of papal authority and sparked the Reformation.
