VATICAN CITY (CNS) – Pope Francis will attend two ecumenical events and celebrate Mass with Catholics when he visits Sweden October 31, according to organizers. The pope’s attendance at an ecumenical commemoration of the 500th anniversary of the Protestant Reformation in Lund, Sweden, will include a prayer service in Lund Cathedral and a public event at Malmo Arena, said a joint press release June 1 from the Lutheran World Federation and the Pontifical Council for Promoting Christian Unity. However, the pope’s complete itinerary “will be published at a later date,” Jesuit Father Federico Lombardi, Vatican spokesman, told journalists June 1. “It was important that no one would think that just because we released the joint statement, that they were the only events in the pope’s schedule,” Father Lombardi said. Pope Francis, alongside Bishop Munib Younan, president of the Lutheran World Federation, and the Rev. Martin Junge, the federation’s general secretary, will lead a common prayer service “based on the recently published Catholic-Lutheran “Common Prayer” liturgical guide. The guide is based on “From Conflict to Communion,” a joint document that highlights the ecumenical developments between the two churches.
