September 1 - Pope Francis U.S. Visit 2015 Schedule and Dates: Pontiff Invites Rick Warren To Speak at Philadelphia Conference on Family 

Rick Warren, senior pastor of Saddleback Church, has announced he will be speaking in Philadelphia later this month at the World Meeting of Families event to commence Pope Francis' highly anticipated visit to the United States. Warren announced his plans to attend the event during the Sunday morning worship service at the Lake Forest, CA church.
 
"Next month, Pope Francis is coming to America for a world gathering on families," he told the congregation. "I'm not a Catholic, and we have many differences with Catholics. But they love the Lord and we have much in common with that - we believe in the Bible, and the Trinity, and in Jesus and the resurrection." "There are probably going to be a million people in Philadelphia at this final event with Pope Francis, and he's asked me to be the final speaker," the Purpose Driven Life author continued amid cheering and applause.
