An artwork of Father Junipero Serra with Native Americans is displayed at the Carmel Mission in Carmel, California May 5, 2015. Pope Francis intends to declare Serra a saint at a Mass celebrated at the National Shrine in Washington on Sept 23 during his U.S. visit. The Franciscan friar built a series of missions along the Pacific coast in the latter 18th century, in what is now California, to spread the faith among Native Americans. REUTERS/Michael Fiala
