President John F. Kennedy stands with Pope Paul VI at an audience in the Vatican July 2, 1963. Kennedy's meeting with Pope Paul VI at the Vatican was historic: the first Roman Catholic president of the United States was seeing the Roman Catholic pontiff only days after his coronation. Kennedy _ who struggled against anti-Catholic bias during his presidential campaign _ only shook hands with the pope rather than kissing his ring, as is the usual practice for Catholics. (AP Photo)
