Pope Benedict XVI greets U.S. cardinal Bernard Law after his weekly general audience in the Paul VI Hall at the Vatican, Wednesday Feb. 13, 2013. Looking tired but serene, Pope Benedict XVI told the thousands who gathered for his weekly audience that he was resigning for "the good of the church", an extraordinary scene that unfolded in his first appearance since dropping the bombshell announcement. The 85-year-old Benedict basked in more than a minute-long standing ovation when he entered the packed hall for his traditional Wednesday catechism lesson. He was interrupted repeatedly by applause, and many in the audience of thousands had tears in their eyes. (AP Photo/Alessandra Tarantino)
