Pope Benedict XVI called on Christians to lead a life that's "coherent" with their beliefs in his last public address before becoming the first Roman Catholic pontiff in six centuries to leave power.
The German-born Benedict, 85, addressed a general audience of tens of thousands of pilgrims in St. Peter's Square today. Entering the 17th-century square in the "Popemobile" for a final blessing, he spoke from a stage in front of St. Peter's Basilica. Benedict will become the first pope tomorrow to leave office since Gregory XII in 1415.
