Pope Benedict will honour the 16th century Protestant reformer Martin Luther on his state visit to Germany next month, but Roman Catholic officials are warning Lutherans not to expect breakthroughs on issues dividing them. During the Sept 22-25 visit, the German-born pontiff plans to stress ecumenical cooperation, meet Protestant leaders and tour a monastery in Erfurt where Luther once worked and prayed. He will also address the German parliament in Berlin.
