People receive the communion as Pope Francis celebrates Mass at the National Shrine of the Immaculate Conception for the Canonization Mass for Friar Junipero Serra in Washington September 23, 2015. Pope Francis took one of the most controversial steps of his U.S. visit on Wednesday when he canonized an 18th-century missionary known by admirers as the "Apostle of California" but accused by Native Americans of helping to eradicate their culture.
