People pray during a Mass at Westminster Cathedral, in London, which is the Mother Church for Roman Catholics in England and Wales, Monday, Feb. 11, 2013. Pope Benedict XVI said Monday he lacks the strength to fulfill his duties and on Feb. 28 will become the first pontiff in 600 years to resign. The announcement sets the stage for a conclave in March to elect a new leader for the world's 1 billion Catholics. (AP Photo/Matt Dunham)
