Pope Francis, Catholics and Lutherans Will Recall Reformation

Nearly 500 years ago, Martin Luther nailed his 95 theses to the door of a German church, beginning the Protestant Reformation that led millions to break with the Roman Catholic Church and ushered in more than a century of conflict and war.
On Monday, the Vatican announced that Pope Francis will participate in a joint Lutheran-Catholic worship service in Sweden this October, kicking off a series of events planned for 2017 to commemorate the 500th anniversary of the Reformation. NY Times
