The Vatican today announced the one-day trip on October 31, the first papal visit to Sweden since 1989 when Pope John Paul II visited.
The Lutheran World Church said in a separate release that the event, being held ahead of the Reformation anniversary in 2017, was meant to highlight "the solid ecumenical developments between Catholics and Lutherans."
Celebrations will include a common worship based on a recently published Catholic Lutheran liturgical guide. Martin Luther's challenge to the Catholic doctrine of indulgences in 1517 is remembered as the start of the Reformation.
