A demonstrator opposing the visit of Pope Benedict XVI to Germany, wearing a T-shirt reading 'Never again', takes part in a protest rally in front of the Brandenburg Gate in Berlin September 22, 2011. Pope Benedict appealed to Catholics not to leave the Catholic Church as he arrived on Thursday for a four-day visit to Germany, where record numbers of the faithful have quit the pews in protest against clerical sex abuse scandals.
